When putting the application in the background and switch to another app, onMapCreated is called. Indeed it is called twice...

  _onMapCreated(MapboxMap mapboxMap) async {
    print("onMapCreated");
}

EDIT:

import 'package:flutter/material.dart';
import 'package:mapbox_maps_flutter/mapbox_maps_flutter.dart';

void main() async {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: MapView(),
    );
  }
}

class MapView extends StatefulWidget {
  const MapView({super.key});

  @override
  State<MapView> createState() => _MapViewState();
}

class _MapViewState extends State<MapView> {
  
  _onMapCreated(MapboxMap mapboxMap) async {
    print("onMapCreated");
  }

  @override
  Widget build(BuildContext context) {
    return MapWidget(
      cameraOptions: CameraOptions(
          padding: MbxEdgeInsets(
              bottom: (MediaQuery.of(context).size.height -
                      kBottomNavigationBarHeight -
                      MediaQuery.of(context).padding.top) *
                  0.15,
              left: 0,
              right: 0,
              top: 0),
          zoom: 4,
          center: {
            "coordinates": [9.142084916929944, 49.97744579860142]
          }),
      resourceOptions: ResourceOptions(
          accessToken:
              "XXX"),
      onMapCreated: _onMapCreated,
    );
  }
}

Is it possible to opt-out of sending telemetry data via code, e.g. to include this setting in the app settings? Currently the only way I'm finding is via the attribution button.

If it is not currently possible, are you planning to provide that option? When reading about telemetry on the Mapbox-Website it is being stated often that this should also be possible via settings in the app aside from the attribution button?

The Mapbox community Flutter plugin (originally the official predecessor of this plugin) has this option: https://pub.dev/documentation/mapbox_gl/latest/mapbox_gl/MapboxMapController/setTelemetryEnabled.html

It also looks like both the native SDKs support the option to opt-out programmatically:

• Android: https://docs.mapbox.com/android/maps/api/10.10.1/mapbox-maps-android/com.mapbox.maps.module/-map-telemetry/set-user-telemetry-request-state.html
• iOS: https://docs.mapbox.com/help/getting-started/attribution/#mapbox-maps-sdk-for-ios ("Integrate the setting directly into your app. Hook a UISwitch control up to the MGLMapboxMetricsEnabled standard user defaults key, which should be true by default. Then set MGLMapboxMetricsEnabledSettingShownInApp to YES in your app’s Info.plist file.")

Can i somehow make a nice looking circle marker with a text on top of it directly in the map without giving it an image?

How can I update the source when it's already in the map? Do I have to remove it first? I wrote such a method:

  Future<void> _removeSourceIfExists(String sourceId) async {
    if (!mounted) return;
    if (await mapController.style.styleSourceExists(sourceId)) {
      await mapController.style.removeStyleSource(sourceId);
    }
  }

  Future<void> _addSource(String sourceId, Map<String, dynamic> geojson) async {
    await mapController.style
        .addSource(GeoJsonSource(id: sourceId, data: json.encode(geojson)));
  }

But when removing a source, I get the error :

PlatformException (PlatformException(Throwable, java.lang.Throwable: Source 'markerSource' is in
use, cannot remove, Cause: null, Stacktrace: java.lang.Throwable: Source 'markerSource' is in use, 
cannot remove

I also tried just adding the updated source, without removing it beforehand, but then I get the following error:

PlatformException (PlatformException(Throwable, java.lang.Throwable: Source markerSource already exists, 
Cause: null, Stacktrace: java.lang.Throwable: Source markerSource already exists
at com.mapbox.maps.mapbox_maps.StyleController.addStyleSource$lambda-21(StyleController.kt:256)

Why is this printing null to the console?

  await mapboxMap?.style.addStyleSource(
          "chargers",
          json.encode({
            "type": "geojson",
            "data": {
              "type": "FeatureCollection",
              "features": [
                {
                  "id": "39169",
                  "type": "Feature",
                  "properties": {
                    "fastCharger": false,
                    "powerKW": "22 KW",
                    "name": "Rathaus Altona"
                  },
                  "geometry": {
                    "type": "Point",
                    "coordinates": [9.93550387483399, 53.5464387674623]
                  }
                },
              ]
            },
            "cluster": true,
            "clusterMaxZoom": 14,
            "clusterRadius": 50
          }));

      final GeoJsonSource source =
          await mapboxMap.?.style.getSource("chargers") as GeoJsonSource;

      print(await source.data); ==> null

I want to have a limit for the camera zoom, something like maxZoom = 20 and minZoom = 7.

So far I've forced this behaviour in the onCameraChangeListener event by doing this:

 await mapboxMap!.getCameraState().then((value) {
            if (zoom >= minZoom) {
              zoom = value.zoom;
            } else {
              zoom = minZoom;
              mapboxMap!.setCamera(CameraOptions(zoom: minZoom));
            }
          });

But it doesn't feel "clean", because every time I try to go over the threshold, the map starts to "vibrate". Is there a better way to do this? Or am I missing something?

Using mapboxMap.style.getLayer() will throw exception if layer properties are using expressions. In the sample code bellow, which is using default mapbox light style, text-size property is using the following expression, which is List<dynamic> when decoded, but double is expected.

"text-size": [
    "step",
    ["zoom"],
    ["step", ["get", "sizerank"], 18, 5, 12],
    17,
    ["step", ["get", "sizerank"], 18, 13, 12]
],

Reproduction code:

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  late final MapboxMap _map;

  void _mapCreated(MapboxMap map) {
    _map = map;
  }
  
  void _onStyleLoaded(StyleLoadedEventData event) async {
    await _map.style.getLayer('natural-point-label');
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Get Symbol Layer Exception',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        body: MapWidget(
          resourceOptions: ResourceOptions(accessToken: <add access token>),
          styleUri: MapboxStyles.LIGHT,
          onMapCreated: _mapCreated,
          onStyleLoadedListener: _onStyleLoaded,
        ),
      ),
    );
  }
}

When running this code the following exception is thrown:

E/flutter (22989): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: NoSuchMethodError: Class 'List<dynamic>' has no instance method 'toDouble'.

I think this is a major issue because we can add our own layers which are using expressions but can't retrieve the same layer later.

First of all thanks for getting this out and making the source code public!

Whats the timeline for offline support? We would need that feature before we can migrate.

We want to show a selection on the map. With Mapbox GL JS we had different strategies to achieve this. Filter the source data or update the source to represent the selected data.

I don't see how we can represent a selection.

See this example with the filter strategy:
https://docs.mapbox.com/mapbox-gl-js/example/using-box-queryrenderedfeatures/

See this example for the setData method on the source. This could be usefull for multiple scenario like show realtime data
https://docs.mapbox.com/mapbox-gl-js/example/live-update-feature/
map.getSource('trace').setData(data);

Hello.
I got some problems. So I want to share it.
I have 2 screens. They are both using MapWidget. In 1st screen, I created a line layer and source [line_source_view_info] for that layer. It worked.
When I go to the 2nd screen, it throwed this exception "java.lang.Throwable: Source line_source_view_info is not in style". I think that source data is not removed/disposed in the right way.
So could you please take a look. Thank you

When creating multiple map instances all map controllers are working with the data from the map which was created last. The issue can be observed with the following reproduction code.

import 'package:flutter/material.dart';
import 'package:mapbox_maps_flutter/mapbox_maps_flutter.dart';

void main() {
  runApp(const MyApp());
}

      ),
    );
  }
}

class MapPage extends StatefulWidget {
  const MapPage({Key? key}) : super(key: key);

  @override
  State<MapPage> createState() => _MapPageState();
}

class _MapPageState extends State<MapPage> with AutomaticKeepAliveClientMixin {

}

class PageSwitch extends StatelessWidget {
  const PageSwitch({
    Key? key,
    required this.page,
    required this.bgColor,
    required this.onTap,
  }) : super(key: key);

  final int page;
  final Color bgColor;
  final void Function(int) onTap;

  @override

          child: Center(child: Text('$page')),
        ),
      ),
    );
  }
}

Copy the code to main.dart file and run the app.

Steps to reproduce:

1. Scroll the map to a random point and click the blue rectangle on the right to get the CameraState.
2. Click the green rectangle on the bottom to switch to the second map and repeat the first step.
3. Click the blue rectangle on the bottom to switch to third map and repeat the first step.

And then go to the first or the second map and click again the blue rectangle to get the CameraState and it will be the state from the map which was created last. This is happening with every action that can be done on the map.

Now I get this trying to launch on Android:

When we have initial screen which contains map, and we push and pop a route with other map, calling functions on map which is on initial screen throws PlatformException. Generally creating and destroying map even without pushing and popping routes is causing the same exception. For example, we have a widget which is initially off screen, and when user clicks a button, widget slides in and displays a map which is destroyed when the user is finished with that widget.

Reproduction code:

void main() {
  runApp(const MaterialApp(
    home: MyApp(),
  ));
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  MapboxMap? _map;
  bool _styleLoaded = false;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('First Map'),
      ),
      body: Stack(
        children: [
          MapWidget(
            resourceOptions: ResourceOptions(accessToken: <add access token>),
            styleUri: MapboxStyles.LIGHT,
            onMapCreated: (MapboxMap map) => _map = map,
            onStyleLoadedListener: (StyleLoadedEventData event) => _styleLoaded = true,
          ),
          Positioned(
            left: 16,

            child: ElevatedButton(
              onPressed: () => Navigator.push(
                context,
                MaterialPageRoute(builder: (context) => const SecondRoute()),
              ),
              child: const Text('Second map'),
            ),
          ),
          Positioned(
            right: 16,
            bottom: 16,
            child: ElevatedButton(
              onPressed: () {
                if(_styleLoaded) {
                  _map!.style.styleLayerExists('layer_id');
                }
              },
              child: const Text('Map action'),
            ),
          ),
        ],
      ),
    );
  }
}

class SecondRoute extends StatelessWidget {
  const SecondRoute({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Second Map'),
      ),
      body: MapWidget(
        resourceOptions: ResourceOptions(accessToken: <add access token>),
        styleUri: MapboxStyles.LIGHT,
      ),
    );
  }
}

Steps to reproduce:

1. Click on Second Map button.
2. Go back to previous screen.
3. Click on Map action button.

I'm using the latest version of the library, but didn't find a way to customize the marker in a particular way, currently it just adjusts to the built-in method which is difficult to customize again.

Only the LogoSettingsInterface is exposed via MapboxMap.logo.

There is no way to hide the ScaleBox via code. However, we can see that the necessary classes and interfaces to modify the ScaleBox and other counterparts are available but not exposed to use.

Please expose MapboxMap.scaleBox and MapboxMap.attributions with the next version.

When will it be possible to view annotations? Next update I hope. Now the fact that this feature is not available yet I can't use the plugin and need to use unofficial that's a bit unstable.

Hello, I have tried to make the settings to show the traffic layer on the map without success, I have followed the indications of the examples but I have not got an example of traffic with flutter.

      mapboxMap.style.addSource(VectorSource(
          id: "traffic", url: "mapbox://mapbox.mapbox-traffic-v1"));

      mapboxMap.style.addLayerAt(
          LineLayer(
            id: "traffic",
            sourceId: "mapbox-traffic",
            sourceLayer: "traffic",
            lineWidth: 1.9,
          ),
          LayerPosition(above: "country-label"));

This is the code I have implemented, following the example of the VectorTileSourcePage class. Please could you help me by telling me what other settings I should apply.

How can I update my clusters, after filtering the layer of single points? The single points are responding to the filter, but the clusters are not updating to reflect the new amount of single points on the map.

I checked source of SymbolLayer. But it seems it does not contain any properties to set text value. I am very confusing because we had all other properties for text like textColor, textSize,... But no definition for setting value for text.
Thank you.

Would be great to have desktop (MacOs/Windows/Linux) support for maps

If in addition to mapbox_maps_flutter add another mapbox plugin(in my case flutter_mapbox_navigation) it throws this error.
Any idea on what might be done to fix it would be highly appreciated. Thanks.

During testing on a Samsung galaxy A52S 5g I have noticed the phone heating a lot when the mapbox default location marker is enabled compared to if it is disabled.

I am using the following to set the location enabled:
_mapController?.location.updateSettings(LocationComponentSettings(enabled: true));

Have someone else noticed similar behaviour?

I'm trying to get my location from the map to avoid using external libraries like geolocator, but I can't find any option nor listener for the user location.

At the start of my view I want to center the camera at the current user location. Is there any way to do that in the current version of the plugin?

I need to update the data on my map if it possible at the end of, for example, the camera movement, to avoid getting too much data from my API. I've already done this in web by using onDragEnd but I can't find a simple way to do this in this plugin. I basically need something like these Events, or the equivalent for the camera position.

Is there a way to do this? I found mapboxMap.addListener() but I'm not sure about how it works and if it can listen to those events.

Hi, and firstly, well done with the plugin. It is phenomenal!
Our team has been using the other unofficial plugin for a few years now. It was the best there was, but we had extreme performance issues and some difficulty adding custom layers, etc.
We finally hacked in layer/layer-style support, but it's not great.

Your plugin is extremely fast, I've been testing it for viability for the last two days.
So far only this one possible deal breaker.

In our app we use, e.g. symbol layers where the symbols have filters that make them disappear at zoom level 5 and below and also reduces their size linearly based on zoom level. We can also set symbol images on a single layer based on expressions such as the GET expression from the Mapbox docs.

Are there any plans to allow for adding these expressions?
I see currently when creating a layer you can only set a size of type double, as an example.

I'm gonna explore your code a bit and see if I can somehow pass in custom JSON directly somewhere, but the layer data classes do make things a lot easier.

Hi, since I'm migrating from a community driven mapbox package, to this one, I am struggling to find an equivalent for

  void _onMapCreated(MapboxMap mapController) {
    this.mapController.onFeatureTapped.add(_onTappedFeature); // this line
  }
  
    Future<void> _onTappedFeature(
    feature,
    Point<double> point,
    LatLng latlng,
  ) async {
  ...
  }

What is the equivalent or similar thing for that in the official package?

How can I extract the coordinates of the center of the map?

Hello. First of all, I really love this project. Thank you so much for your working on it. I am now stucking with passing custom data through PointAnnotaion.

I have some markers/anotations on the Map. When clicking on a marker, base on the marker's id, it will get data of that marker and display it. But it seems that there is no field for that purpose in PointAnnotation.

Here is my source. How can I do this?

@OverRide
void onPointAnnotationClick(PointAnnotation annotation) async {
Navigator.pushNamed(mapState.context, Routes.viewPinInfo, arguments: annotation.customData.id);
}

This is my Cluster source:

{
  "type": "geojson",
  "data": "https://firebasestorage.googleapis.com/v0/b/charge-club.appspot.com/o/chargers.json?alt=media&token=0146c264-4e84-4af3-a6e0-8bb4992314d1",
  "cluster": true,
  "clusterMaxZoom": 14,
  "clusterRadius": 50
}

This is my Cluster layer:

{
  "id": "clusters",
  "type": "circle",
  "source": "chargers",
  "filter": [
    "has",
    "point_count"
  ],
  "paint": {
    "circle-color": [
      "step",
      [
        "get",
        "point_count"
      ],
      "#54FACF",
      100,
      "#54FACF",
      750,
      "#f28cb1"
    ],
    "circle-radius": [
      "step",
      [
        "get",
        "point_count"
      ],
      20,
      100,
      30,
      750,
      40
    ]
  }
}

I also have a layer for the unclustered points:

{
  "id": "unclustered-point",
  "type": "symbol",
  "source": "chargers",
  "filter": ["!", ["has", "point_count"]],
  "layout": {
    "icon-image": [
      "case",
      ["boolean", ["get", "fastCharger"], false],
      "fastCharger",
      "charger"
    ],
    "icon-anchor": "bottom",
    "text-field": ["get", "name"],
    "text-anchor": "bottom",
    "text-offset": [0, -3.3],
    "text-size": 14,
    "text-ignore-placement": true,
    "icon-ignore-placement": true,
    "text-padding": 0
  },
  "paint": {
    "text-color": "#fff",
    "text-halo-color": "#000",
    "text-halo-width": 1,
    "text-opacity": [
      "case",
      ["boolean", ["feature-state", "selected"], false],
      1,
      0
    ],
    "icon-opacity": [
      "case",
      ["boolean", ["feature-state", "selected"], false],
      1,
      0.7
    ]
  }
}

When setting a filter to the unclustered layer, the cluster is not updating. The single points are working correct, but the cluster do not reflect the new amount of single points.

 await mapboxMap?.style.setStyleLayerProperty("unclustered-point", "filter",  '["==", "fastCharger", true]');

The layers and sources are added in the onMapCreated method of the Map Widget:

    mapboxMap?.style.styleLayerExists("clusters").then((value) async {
      if (!value) {
        var layer =
            await rootBundle.loadString('assets/cluster/cluster_layer.json');
       mapboxMap?.style.addStyleLayer(layer, null);

        var clusterCountLayer = await rootBundle
            .loadString('assets/cluster/cluster_count_layer.json');
        mapboxMap?.style.addStyleLayer(clusterCountLayer, null);

        var unclusteredLayer = await rootBundle
            .loadString('assets/cluster/unclustered_point_layer.json');
        mapboxMap?style.addStyleLayer(unclusteredLayer, null);

      }
    });

Hi, I love this plugin and I want to say thank you!

I am looking to implement toScreenLocation() function which is in mapbox-gl.
With this function, you can convert latitude and longitude coordinates to screen coordinates.

/// Returns the point on the screen that corresponds to a geographical coordinate ([latLng]). The screen location is in screen pixels (not display pixels) relative to the top left of the map (not of the whole screen)
  ///
  /// Note: The resulting x and y coordinates are rounded to [int] on web, on other platforms they may differ very slightly (in the range of about 10^-10) from the actual nearest screen coordinate.
  /// You therefore might want to round them appropriately, depending on your use case.
  ///
  /// Returns null if [latLng] is not currently visible on the map.
  Future<Point> toScreenLocation(LatLng latLng) async {
    return _mapboxGlPlatform.toScreenLocation(latLng);
  }

FROM: https://github.com/flutter-mapbox-gl/maps/blob/f505fcf5c79b75c165703028af77f3af62d382ae/lib/src/controller.dart#L1211-L1219

While it appears to be possible to stack annotations relative to each other within the same manager, I am struggling to reorder different annotations; in my specific case I want a PolylineAnnotation to be displayed below some PointAnnotations, however the line remains steadily above the icons:

Notice how the line comes out of the avatar and overlays it; instead I'd like to have the avatar above the line.

I added some feedback in a Github repo before this one was made public: motrieux-thomas/mapbox_maps_flutter-0.3.0#1 (comment).

I think it would be good to address them:

• The API for setting location is quite weird. We don't actually have a toJson function on Point. It's not exactly clear how the Map should look. Please consider using a LatLng (or find a better name) type which you provide the serialization for (rather than asking us to provide a JSON). Instead of:

  /// Coordinate at the center of the camera.
  Map<String?, Object?>? center;

do

LatLng center;

• Package documentation assumes people have turf (https://pub.dev/packages/turf) installed, since that is how they can do Position(-80.1263, 25.7845)).toJson(). This is kind of confusing, since docs don't mention turf. It would be good to avoid asking developers to instead turf though.
  

• Please consider renaming the controller type to MapController or MapboxController. It's confusing that the map widget is MapWidget, and the controller is MapboxMap. The convention is to suffix names Controller if they are controllers.

How do I disable the compass, or change it's appearance - since it looks awful on Android)?

Also would like to disable the scale showing up in the upper left corner of the map.

I'm trying to add an image (Uint8List) to the maps style, so that I can reference it later in a feature when I assemble a source geojson. This is what I tried:

    ByteData byteData =
        await rootBundle.load('assets/map_icons/$assetName.png');
    Uint8List image = byteData.buffer.asUint8List();
    // So far everything is okay, the list is correct.
    // But here I struggle with understanding what half of the properties do. The next line throws an error.
    await mapController.style.addStyleImage(
      assetName, // A string (which I later use to reference the image in a geojson source)
      1,
      MbxImage(width: 50, height: 50, data: image),
      true,
      [],
      [],
      null,
    );
    

The error thrown is:

How can I make it impossible for the user to pitch the map using a two finger gesture?

PointAnnotation dimiss when I call annotationManager.update()

I am using a "addOnPointAnnotationClickListener" to allow click on the symbols for a specific screen however when i dispose the current screen and navigate to a different screen with other symbols the listener is still active.

Is there an option to dispose/cancel the listener? Could not find any info in the documentation.

Btw great to see official mapbox support to flutter!

Hi

I used CoodinateBounds with an empty map for southwest and northeast and setting infiniteBounds to true.
Like this:

CoordinateBounds(
        infiniteBounds: true,
        southwest: {},
        northeast: {},
      );

The doc says that for infiniteBounds property: "If set to true, an infinite (unconstrained) bounds covering the world coordinates would be used. Coordinates provided in southwest and northeast fields would be omitted and have no effect."

My problem is that I got this error:
Unhandled Exception: PlatformException(NullPointerException, java.lang.NullPointerException: null cannot be cast to non-null type kotlin.collections.List<kotlin.Double>, Cause: null, Stacktrace: java.lang.NullPointerException: null cannot be cast to non-null type kotlin.collections.List<kotlin.Double>

I suppose that southwest and northeast are not omitted as they would be.

Hello, how can I use data driven properties to pass a color for a line on LineLayer? The LineLayer object takes an int for the line-layer property, so I can't pass the ['get', 'custom-color'] to it :/ Actually that applies to any property in any type of layer...

After turning off the map rotation does not work vertical scrolling on the map. How to solve this problem?

mapboxMap?.gestures.updateSettings(GesturesSettings(rotateEnabled: false));

How to display a info window?

The README states that "Web and desktop are not supported" - I'm wondering if that's a limitation as of this moment, or something that you don't intend to support even if the implementation is done by someone?

flutter run gives an error related to referencing ktlint.gradle.

* Where:
Build file '/Users/praveen/development/flutter/.pub-cache/hosted/pub.dartlang.org/mapbox_maps_flutter-0.3.0/android/build.gradle' line: 57

* What went wrong:
A problem occurred evaluating project ':mapbox_maps_flutter'.
> Could not read script '/Users/praveen/***/android/gradle/ktlint.gradle' as it does not exist.

Upon checking the library, it's referencing these two files on the root directory.

project.apply {
    from("$rootDir/gradle/ktlint.gradle")
    from("$rootDir/gradle/lint.gradle")
}

The end user need not have these files.

Hey there,
as there is no listener for a tap on the map (but not on a marker), how do we do that?
Is there an ordering to the call sequence of listeners? Like, is the onTapListener always called before the onPointAnnotationClick listener? Can we rely on that?

Also: i need to be able to cluster (so i will have to go with a GeoJson source), but how does a onTap work then (i dont have PointAnnotations anymore, so no onPointAnnotationClickListener)... do i have to map the coordinates from onTapListener to a entity from my GeoJson source?

Cheers and thanks!
