ricnaaru / adv_camera Goto Github PK

Thanks for the great work on this library, it was easy to get started with the flash and camera rotation.

One issue I'm having is that when the picture is taken, the path is empty. Happy to provide more details, I'll start with that I'm testing on an Android 10 Samsung Galaxy S9.

Is this something that sounds familiar?

On official camera plugin, I can get all frames by
await _controller.startImageStream((CameraImage image)
and process image like this
FirebaseVisionImage.fromBytes(
_concatenatePlanes(image.planes),
_buildMetaData(image, _rotationIntToImageRotation(imageRotation)),
)

How I can do this with adv_camera?

In Android, when you put multiple pages (navigate from one page to another). each with AdvCamera, in the second one there will be a blank screen instead of the preview.

I believe this is related to: #22

Hi Sir I have error in switch camera front.

Hi,

is it possible to force camera focus on camera preview?
Now we have to tap screen for focus.
Thanks.

I'm attempting to use this package, but it seems to crash as soon as i take an image on android 9 and 10, but works fine on android 8. This is the error I get:

Hello,
Flash functionality doesn't work in any configuration for me with adv_camera.
I tested setting flash type in different configuration and in every configuration nothing happens.

Tried by setting flashtype to FlashType.torch on initialization:

return Positioned(
        top: 0,
        left: 0,
        bottom: 0,
        right: 0,
        child: Center(
            child: AdvCamera(
              initialCameraType: CameraType.rear,
              onCameraCreated: _onCameraCreated,
              onImageCaptured: _onImageCaptured,
              flashType: FlashType.torch,
        )));

Tried to iterate over flash types by clicking on screen button

CameraOptionButton(
        icon: _getFlashIcon(),
        onTapCallback: () {
          FlashType newFlashType;
          switch (this.flashType) {
            case FlashType.off:
              newFlashType = FlashType.auto;
              break;
            case FlashType.auto:
              newFlashType = FlashType.on;
              break;
            case FlashType.on:
              newFlashType = FlashType.torch;
              break;
            case FlashType.torch:
              newFlashType = FlashType.off;
              break;
          }
          setState(() {
            flashType = newFlashType;
          });
          cameraController.setFlashType(FlashType.torch);
        })

Confirmed that button works and values here are changed but nothing happens with flashlight.

Expected result: Flashlight is used according to flashtype value.
Result: Nothing happens, flashlight is disabled and didn't flash when photo is taken.

Tested that on Blackberry Key one and Xiaomi Mi6 (both android devices).
All of other adv_camera api like switchCamera, turnOffCamera works fine. There are no errors in terminal.

Any thoughts?

My project was upgraded from version 1.3.1+1 to version 2.0.0+1-nullsafety , and the following problems occurred after operation. Could you please tell me what might cause this?

Hey there,
As you have mentioned that there is a tap to focus method through which we can get focus but, as i have a use case where i have to use stack and i want focus on some point for a longer duration but when we tap i can get focus for 1 or 2 sec and the the focus is again removed is there any way by which i can customize the way the focus has been test.
Please help me out

I tried running the project example locally but get

error: No profiles for 'com.ric.advCameraExample' were found: Xcode couldn't find any iOS App Development provisioning profiles matching 'com.ric.advCameraExample'. Automatic signing is disabled and unable to generate a profile. To enable automatic signing, pass -allowProvisioningUpdates to xcodebuild. (in target 'Runner' from project 'Runner'

Tried messing around with the pod files to no avail. Am I missing something for the setup?

I've got this error after picking an image from gallery using image_picker package on iOS simulator running iOS 14.3:
Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value: file adv_camera/AdvCamera.swift, line 371

This is the line 371 in AdvCamera.swift:
let devicePoint: CGPoint = (self.videoPreviewLayer).captureDevicePointConverted(fromLayerPoint: touchPoint)

I can't seem to comprehend what is the link between picking an image with image_picker and this package, but thought you may need to know about this.

This code opens rear camera:

child: AdvCamera(
                            initialCameraType: CameraType.front,
                            onCameraCreated: _onCameraCreated,
                            onImageCaptured: (String path) {
                              setState(() {
                                imagePath = path;
                              });
                            },
                            cameraPreviewRatio: CameraPreviewRatio.r16_9,
                          ),

I'd been trying to implement some custom controls for a camera view and tried calling controller.setFlashType with both FlashType.on and FlashType.torch values, but it seems like it isn't working. controller.captureImage() does not trigger any flash whatsoever. I've tested it on multiple android devices, yet no luck getting it to work.

How do I stop the camera after capturing an image?

For error handling it will be great to have external initializer that you can run in initState or by pressing a button and creating a controller.

I get this error after I take a photo. Camera freezes and can't take pictures again.

Android sdk 28 - emulator
flutter 1.9.1.hotfix.5

hi , richardothayeb. with me the adv_camera is very helpful.
I want to be able to get data directly instead of saving it to disk first, which can better optimize the process. I tried to change your source code, but I failed because of lack of ability.
If you don't mind, can you provide some guidance, or provide a method to get the picture data directly for manual processing. Thanks♪(･ω･)ﾉ

no error in the code but it is not showing any preview. I tried with both android emulated and also real device. but its showing only the progress bar. I used the latest version (adv_camera: ^1.1.1+1). android version - 7,8,9

please help...

Will support be added for video recording?

I've tried to run the example you provided without any changes in code.
The problem is detected on iOS on iPhone 6s plus device.

As you can see on the screenshot

below, the camera is not showing a preview, but functionally it works: the camera switch is working and the image capturing is fine.

The only problem is in the camera preview which is not working without any errors in logs.
Here is the Flutter doctor output:

In my application, I use the newest version of adv_camera - 2.0.1.
With Android, it works fine, but when I try to run
flutter run on iOS I've got an error:

[... lot of warnings ...]
/Users/mac/tools/flutter/.pub-cache/hosted/pub.dartlang.org/adv_camera-2.0.1/ios/Classes/AdvCamera.swift:207:17: error: call to method 'setupLivePreview' in closure requires explicit use of 'self' to make capture semantics explicit
[... lot of warnings ...]

It looks like this line is treated as an error with a set to platform :ios, '10.0' . But version 10.0 is the minimum supported version with Firebase libraries version 8 and above.

Any ideas?

I recieve this unhandled exception whenever i open a camera using adv_camera:

I already uninstalled and installed the plugin again and the error continues

Camera preview not showing and when i clicked torch and change to front camera app is crash.

The camera works good except that the front camera is not showing a preview, I have been testing with different phones but I have a Xiaomi MI 9T pro, with a popup camera. So when I call switch camera my front camera comes up so it is being called. But the preview freezes from the backcamera and is not updating to the front camera preview.
Any idea's?

MissingPluginException(No implementation found for method turnOff on channel plugins.flutter.io/adv_camera/2)

When the app is minimized the camera still running at background, the battery is drained and the mobile flashlight is locked.

It will be great to choose where to save the photo if I need to process it for example I don't need to save it to library.

How can i save image by custom path? For example in android not in a ../images/name.jpg , but in a ../some_path/name.jpg .
This is important for my project.

Currently there's no way to dispose of the camera resource after instantiating the cam widget. This leads to the "camera in use" green dot on ios to show up.

Calling "camController.turnOff" doesn't seem to deallocate everything

Please, add new param for JPEG compression quality. Now is static 100

The problem I found out with my app is in these lines in 'checkForPermission' method in AdvCameraPlugin.java:
Dexter.withActivity(activity) .withPermissions(Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE)

I suggest that better approach would be this:
Dexter.withActivity(activity) .withPermissions(Manifest.permission.CAMERA)
Or rather, not requesting storage permission. Here is my reasoning and my personal case:
I implemented a dialog which explain the usage of storage in my app, which is showed before the system dialog of storage permission. The problem is that storage permission for AdvCamera is asked on initialization, so a possible solution is to first show the dialog, then initializate the widget. The problem with this is that storage is not necessary for camera since in a case of permission denial the image could be temporarly saved in a path where storage permission is not required (i.e. Directory.systemTemp), since in my case the image is only used for further processing and upload. But as I checked in the AdvCamera widget, this widget is only initialitied when permissions are successful, which in my case is not good since I would like my users to still take photos even if they don't concede storage permission, if they do the image is just permantly storaged.

So to conclude, for me a better approach would be not to ask storage permissions in both iOS (in this case I didn't check the code) and Android, and leave the duty to ask permissions to the developer with a package like permission_handler (if they need it), or simply just adding an option to disable it in the package.
Thank you and best regards.

Hi when I change initialCameraType to front camera the app opens. but I get a crash and image freeze.
Can you help?

How can i remove the camera initialise Animation in IOS ?

When I set in build.gradle

defaultConfig {
    targetSdkVersion 29
}

camera is oppening but image doesn't taken (or saved). (Play console warn me to set targetSdkVersion to 29)

Hi!

I have this issue with flutter camera plugin and with this too:
flutter/flutter#19038

Can you correct the FPS in this component?
Thanks!

Exception has occurred.

I think there is a solution. They released hybrid composition in Flutter 1.22, which just requires API level 19.

https://flutter.dev/docs/development/platform-integration/platform-views?tab=android-platform-views-kotlin-tab#hybrid-composition

I tried to lower api level but I couldn't do it.
Can you lover min api level to 19?

This is an excellent plugin for using the camera with a flutter.

However I missed an option to enable / disable audio when capturing a photo.

on ios,cant set size and get size.
Is this a question of platform or what? For the first time IOS development, please understand.

Hi, I noticed one possible bug.

My case is as followed:

1. I start my app, and go to camera preview
2. Then I wait, that my phone get LOCKED
3. When I unlock my phone again, I only get white screen in Camera Preview and some weird errors.

Interestingly, that doesn't happen if I put app in the background.

Errors:
