abausg / home_widget Goto Github PK

I have been trying to figure out how to add a ListView with programmatically updatable TextViews within the ListView but I am unsure of how to accomplish this. Does anyone have any suggestions?

Thank you

In HomeWidgetPlugin.kt#L79 a call to result.success is missing.

So when you await updateWidget like below it doesn't finish.

await HomeWidget.updateWidget(
    name: 'WidgetProvider',
    androidName: 'WidgetProvider',
    iOSName: 'WidgetProvider',
);

I haven't personally tested this. If you prefer, I can test and send a PR.

@ABausG When we expect the click from widget to app?

Hello! I am having problems with the library. I tried to integrate the example from the library into my project, but I got the following problem:

I am new to android development. I would really appreciate your help

i have an error when i click the arrow back on android and then i open the app with the home screen widget.

[ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: type 'bool' is not a subtype of type 'String?' in type cast
E/flutter (14900): #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:158:41)
E/flutter (14900): .

this is the erro, i try to check this, but i can't resolved, it just happen when you go back and then u click the widget to open the app again cause android destroy the app, and then idk why cannot rebuild well.
Destroying service.
D/FlutterLocationService(14900): Creating service.
D/FlutterLocationService(14900): Binding to location service.

Right now Platform name needs to be the same for iOS and Android. Add a option to add separate names to be more flexible on naming the Widgets however it suits the platform best

Fairly new to all of this. I had Android working perfectly and tried to add an ios widget. I'm using workmanager to try to update the widget in the back ground. However I am getting this error.

The error also occurs on the example app.

For me this error occurs when I try to get data from an api using the http package.

As I'm new to this - please let me know what you need.

Is it possible to update an ImageView in the widget from Flutter assets? I have a weather app and looking to update the weather forecast icon on the widget, but I'm struggling to figure out how to do it. I can update a resource file, but I'd prefer not to have to have two copies. I'm only a beginner, so using this to learn. Any help would be appreciated. Thanks.

Improve the hints and error messages of the example app indicating that the appGroupId needs to be set on iOS.

We have a widget that shows the current state, filllevel, ... of an energy storage Unit, and we would like to show either Status: OK in black or Status: ERROR in red?

The data for this widget comes from a rest api, is there any way to programmatically update the textfield to red background as soon as the api returns an error? As far as I could see there is only support for updateWidget and set the text and nothing else?

When the user long presses the HomeWidget, the Event selector will be displayed, and then select the corresponding value to display
How should it be achieved?
like this:

I have a fully working IntentTimelineProvider that allows me to choose content for the widget to show from inside my flutter application. This works great.

The only issue is I can no longer seem to update the widget using HomeWidget.update am I missing something or is this a limitation?

Hello,

I applied this library success,
I add more feature when using this.

• Show title & message (done)
• A button for integrate : Play button (doing)
  

I did not found any document details the method like setOnClickListener() (or setTextViewText()) to apply (Even Ctril+Space does not help me also)
So how I implemented a clicked button success?

Please help me indicate that?

As per Flutter engine implementation UIApplication:open is suppose to return false if link is not handled by the plugin.

https://github.com/flutter/engine/blob/138c91c614d742c52aa5432b4cb921f0ff9fdee2/shell/platform/darwin/ios/framework/Source/FlutterPluginAppLifeCycleDelegate.mm#L313-L327

But in home_widget plugin it is always returning true and this blocks plugins like uni_links to get the URL.

I have a fix in #46 that properly returns the flag.

Does this handle multiple instances of same widget?

Is it possible to have multiple widgets that update in the background? I have managed to get two widgets, but cannot get one of them to update in the background.

I have two HomeWidgetProvider Classes, two widget info xml's, two layout xml's, and have two receivers in the manifest. I only have one of the following - I'm assuming this is okay?
<receiver android:name="es.antonborri.home_widget.HomeWidgetBackgroundReceiver"> <intent-filter> <action android:name="com.resortstylebeanbags.localweatherau.action.BACKGROUND" /> </intent-filter> </receiver> <service android:name="es.antonborri.home_widget.HomeWidgetBackgroundService" android:permission="android.permission.BIND_JOB_SERVICE" android:exported="true"/>

We have tried to use a custom Font called Rubik:
https://fonts.google.com/specimen/Rubik

Neither by passing the font to the widget itself, nor with attaching a shared resource from flutter to the native android part. Is this a known limit (of the package/ general) for android as the home widget always inherits the system font?

Could you please add an example of a configurable widget on Android, using flutter activity to configure the widget ?

After following set up instructions and comparing with example app, I'm not sure what the issue might be.

In my AndroidManifex.xml I have:

       <receiver android:name="HomeWidgetExampleProvider" >
           <intent-filter>
               <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
           </intent-filter>
           <meta-data android:name="android.appwidget.provider"
               android:resource="@xml/home_widget_example" />
       </receiver>

And in my android/app/src/main/kotlin/com/someName/app/anotherName/HomeWidgetExampleProvider.kt I have the same code from the example project.
I did add Kotlin support to my Flutter app which was originally configured as Java. After sorting our some build issues, MainActivity.kt path seems to be working, but HomeWidgetExampleProvider.kt in the same directory is not?

Any ideas?

EDIT: I forgot to mention, the example widget will build fine and has the time when initially created, but this error is still thrown and also thrown on subsequent updates from Workmanager periodic task. Time will remain the same as when created.

Hi, After your #53 update, I have just started trying to get my app working on iOS. I had done quite a bit of work on it, so I'm not sure if this is still related, but now I am getting this error:

An error was encountered processing the command (domain=IXErrorDomain, code=2):
Failed to create plugin placeholder for /app path/build/ios/iphonesimulator/Runner.app/PlugIns/HomeWidgetExtension.appex

Underlying error (domain=IXErrorDomain, code=2):

Failed to create promise.

Hi, I want update widget showing data from a http get request every hour.

Where should I place this code? in flutter or somewhere?

I tried this but doesn't work:
Workmanager.registerPeriodicTask('1', 'widgetBackgroundUpdate', frequency: Duration(seconds: 1));
get this error:
Interval duration lesser than minimum allowed value; Changed to 900000. That's the 15 default minutes. Is not possible to reduce this limit anyhow?

My app shows how much money you earn/pay by second so I need a widget to show also same info without opening the app (more info: https://play.google.com/store/apps/details?id=com.drodriguez.profits)

Hey!

Sorry for the question, but how can I debug or test this? For example, I am writing code on the flutter side and run the app, but I want to debug the widget and see the information coming to the widget and debug it. How can I achieve this? I have tried running the project on XCode but nothing happens

In IOS 13 and later, to be able to use background refreshing of the app, the BGTaskScheduler should be used and the UIApplication does not work.

Argument 'name' must be the same as your AppWidgetProvider you wish to update, java.lang.ClassNotFoundException: com.ajay.owadio.HomeWidgetExampleProvider at java.lang.Class.classForName(Native Method) at java.lang.Class.forName(Class.java:454) at java.lang.Class.forName(Class.java:379) at es.antonborri.home_widget.HomeWidgetPlugin.onMethodCall(HomeWidgetPlugin.kt:64) at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler.onMessage(MethodChannel.java:233) at io.flutter.embedding.engine.dart.DartMessenger.handleMessageFromDart(DartMessenger.java:85) at io.flutter.embedding.engine.FlutterJNI.handlePlatformMessage(FlutterJNI.java:692) at android.os.MessageQueue.nativePollOnce(Native Method) at android.os.MessageQueue.next(MessageQueue.java:335) at android.os.Looper.loop(Looper.java:183) at android.app.ActivityThread.main(ActivityThread.java:7656) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:592) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:947) Caused by: java.lang.ClassNotFoundException: Didn't find class "com.ajay.owadio.HomeWidgetExampleProvider" on path: DexPathList[[zip file "/data/app/~~ofh_quxw5tSewumlGyuJXQ==/com.ajay.owadio-mgvxU_hG_RGKA8SOFcf_Gg==/base.apk"],nativeLibraryDirectories=[/data/app/~~ofh_quxw5tSewumlGyuJXQ==/com.ajay.owadio-mgvxU_hG_RGKA8SOFcf_Gg==/lib/x86, /data/app/~~ofh_quxw5tSewumlGyuJXQ==/com.ajay.owadio-mgvxU_hG_RGKA8SOFcf_Gg==/base.apk!/lib/x86, /system/lib, /system_ext/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:207) at java.lang.ClassLoader.loadClass(ClassLoader.java:379) at java.lang.ClassLoader.loadClass(ClassLoader.java:312) ... 14 more , null))

I am unable to solve the issue

initiallyLaunchedFromHomeWidget() function never returns result if the launch was not from a widget.

Please change this

 if(initialUrl != nil) {
    result(initialUrl?.absoluteString)
}

to this
result(initialUrl?.absoluteString)

Hello,

I only do one thing,
It is import your library and run app,
After I exit app manually,
I got exception immediately, as image in below :

In case I don't import your library, It's okay

I'm sure this bug appear from previous version until latest version.
Please prevent this bug,

Thanks,
p/s : Please notice that I hasn't declare < receiver > tag in manifest xml yet_

I got these error logs :

Hello!

This is great package for me that not good at Android and iOS.

I want to create home screen widget like gmail ( topbar + listview widget ) in Android

)

Can I create a listview widget with this package?
And if it is possible, how do we do it?

I have an app with 2 pages: Homepage and Quiz. When the user presses the widget on homescreen, the app opens with first screen Homepage and then the code from _checkForWidgetLaunch

  void didChangeDependencies() {
    Debug.d("Homepage didChangeDependencies");
    super.didChangeDependencies();
    //once the app is started from the widget, this is triggered ad infinitum
    //  _checkForWidgetLaunch();
    //  HomeWidget.widgetClicked.listen(_launchedFromWidget);
  }

calls _launchedFromWidget and navigates to Quiz (Navigator.push).

When close Quiz/back button, the Homepage.didChangeDependencies() is called and the Quiz is stared again! This is an infinite cycle.

I managed to fix this by adding to Homepage.initState()

    // //https://stackoverflow.com/questions/49466556/flutter-run-method-on-widget-build-complete
    WidgetsBinding.instance.addPostFrameCallback((_) => _afterInit());

and in afterInit call the code

 _afterInit() async {
    _checkForWidgetLaunch();
    HomeWidget.widgetClicked.listen(_launchedFromWidget);
  }

I hope this helps other people as well. Maybe consider testing and updating documentation?

Thank you very much for your great effort, it's truly a wonderful and incredibly useful component.

Hi,

At the moment I am registering a workmanager periodic task in my app's initstate to update my widget in the background. This works but it is registering & running the task even though there may be no widgets on the home screen for my app. I'm not sure if there is a way to know when the user adds a widget to the home screen so the workmanager task can be registered at that moment? Or is there another point I should be registering the workmanager task? Your example app uses a button, but that wouldn't work in this instance. So the outcome I'd like is to register the workmanager periodic task when a widget is added.

Thankyou!

Hi, first of all thanks for your package!

When working with home screen widgets on Android, I realized that the background intent (HomeWidgetBackgroundIntent.getBroadcast) sometimes suddenly gets into a delayed state. I thought I implemented something wrong, but after checking, it seems to also happen with the sample from the package (change title on click).

I tested on emulator (API 29) and also on my phone (API 30), it shows the same behaviour.

If it enters the delayed state, the next update happens >10 seconds after a click, sometimes earlier, or sometimes when you click on the widget to open the app (HomeWidgetLaunchIntent.getActivity).

I tried to find something in the logs but without any success.
So I was wondering if you maybe know, what is causing the delays (and maybe how to avoid them) ?

I found it was really hard to make this image be round radius!!

any suggestions?

But plugin was added, flutter get was called many times.

home_widget: ^0.1.5

I see that the registerBackgroundCallback feature released in 0.1.2 version is not available in iOS. Is there a limitation in iOS platform?
I have seen that widgets click in iOS can just open app using DeepLink (like already implemented in that plugin) but I am not sure about it.

I appreciate any answer.

Please consider updating the documentation to remove flutter_workmanager as it looks unmaintained and it straight up crashes on the emulator S as per fluttercommunity/flutter_workmanager#352.

An easy replacement could be https://pub.dev/packages/android_alarm_manager_plus.

I have to say, the code in example can't compile at all, I found that

environment:
  sdk: ">=2.12.0 <3.0.0"

and I have goggled but found there are only one useful tutorial about using home_widget https://medium.com/@ashishgarg1998/how-to-create-home-screen-app-widgets-in-flutter-ce3458f3638e
can you give more example for using home_widget?

When I try clicking on a part of a home widget I get an error:

E/HomeWidgetBackgroundService(11269): No callbackHandle saved. Did you call HomeWidgetPlugin.registerBackgroundCallback?

And then the app crashes.

I think I found a solution for this problem.
If I change

val dispatcher = (call.arguments as Iterable<*>).toList()[0].toString().toLong()

val callback = (call.arguments as Iterable<*>).toList()[1].toString().toLong()

The issue with casting is gone and app registers a background callback and everything works as expected.

Best regards,
Aljosa

Is there any way or example for update widget data on interval when app is killed.

The sample code is not working properly on ios.

There is no way to refresh data from widget using button.

I see code: name: 'HomeWidgetExampleProvider', iOSName: 'HomeWidgetExample');

I don't see about clase HomeWidgetExampleProvider
Where are this?
Thank you for support

I copied files in kotlin/es/antonborri/home_widget_example and launched main.dart but it says Unresolved reference: R

I think that this line makes error.

val views = RemoteViews(context.packageName, R.layout.example_layout).apply {

Do I have to import R to my project?

Hello bro,

I can reload home widget for platform Android,
while platform iOs is not.

I can replace content "..." by other content in platform Android, while can not in platform iOs.

Please tell me what I need to do more.

Code sample :

I used this in main widget as guide told me.

@override
  void initState() {
    super.initState();
    // HOME_SCREEN_WIDGET_ID : nct_home_widget
    HomeWidget.setAppGroupId(Constants.HOME_SCREEN_WIDGET_ID); 
  }

I'm using these code for update data (it works for platform Android)

iOs files structure: (HomeWidgetExample created as Widget Extension in Xcode)

    }

    func getSnapshot(in context: Context, completion: @escaping (ExampleEntry) -> ()) {
        let data = UserDefaults.init(suiteName:widgetGroupId)
        let entry = ExampleEntry(date: Date(), title: data?.string(forKey: "title") ?? "No Title Set", message: data?.string(forKey: "message") ?? "No Message Set")
        completion(entry)
    }

Hey,
is there a way to setup pendingIntentTemplate with background click. If I use
"HomeWidgetBackgroundIntent.getBroadcast(context)"
for setPendingIntentTemplate, then data sent with setOnClickFillInIntent is empty
