@bibash28 : is it crashing when scanning the QR code? could you share the QR code as well
No, it is not crashing while scanning. App is crashing after sometime. There is not specific qr code. @fbernaly
@bibash28 : have you try our example app? could you reproduce with our example app? if yes, share detailed steps to reproduce.
Experienced this also. Crash happens after continuously open and close scanner after some 5-8times.

I believe something is wrong with using 'ResolutionPreset.high'
Here's my OPPO Reno 5 Pro 5G memory profile on 'ResolutionPreset.medium'
It hover around 390MB-450MB but never more than this. Very stable. No crash at all. The detection is a little janky however.
Now here's my test on 'ResolutionPreset.high'
Note that the memory remain 1.2GB even after i navigated to different page. And the app will crash shortly after on high preset. Clearly there are some kind of memory leak going on here.
Thanks @famasf1 for debugging this. Now that you have narrow down the issue I think you (or any other volunteer) can look at how the image is passed from CameraImage to InputImage and from InputImage to the native version in the FlutterMethodChannels. I think those Image conversion methods need a second pair or eyes, and a refactor.
I have some workload and I wont be able to work on this for a while, but contributions are always welcome.
@fbernaly I can help with this (see https://github.com/flutter-ml/google_ml_kit_flutter/issues/536). As far as I can tell, the Flutter layer for ML Kit is pretty thin: an InputImage is just converted into JSON data, then passed to custom, closed source native code, if I am not mistaken. I don't see code anywhere using Java code and the native InputImage type.
The Flutter source for ImageLabeler.processImage(InputImage) is the following:
https://github.com/flutter-ml/google_ml_kit_flutter/blob/master/packages/google_mlkit_image_labeling/lib/src/image_labeler.dart
Beyond this point, it is not possible to get access to the source code and hence it is not possible to investigate what's being done with InputImage instances.
/// Processes the given image for image labeling, it returns a List of [ImageLabel].
Future<List<ImageLabel>> processImage(InputImage inputImage) async {
final result = await _channel.invokeMethod(
'vision#startImageLabelDetector', <String, dynamic>{
'options': options.toJson(),
'id': id,
'imageData': inputImage.toJson()
});
final imageLabels = <ImageLabel>[];
for (final dynamic json in result) {
imageLabels.add(ImageLabel.fromJson(json));
}
return imageLabels;
}
@andynewman10: what do you mean with beyond that point? That method uses Flutter Method Channels to call native API depending on the platform, this is what is next after calling that method:
- Android: https://github.com/flutter-ml/google_ml_kit_flutter/blob/master/packages/google_mlkit_image_labeling/android/src/main/java/com/google_mlkit_image_labeling/ImageLabelDetector.java
- iOS: https://github.com/flutter-ml/google_ml_kit_flutter/blob/master/packages/google_mlkit_image_labeling/ios/Classes/GoogleMlKitImageLabelingPlugin.m
Here is more info about Flutter Method Channels: https://docs.flutter.dev/platform-integration/platform-channels
@bibash28 can you please set the camera resolutions to low because as per the camera package, image streaming work smoothly on low resolution. Thank you
