google_mlkit_face_detection: ^0.13.1
google_mlkit_commons: ^0.11.0
camera: ^0.11.2

[MikhaelGerbet]

exactly the same trouble with exactly the same config

[log] CameraImage format: ImageFormatGroup.yuv420, raw: 35
[log] Erreur dans applyFilter: PlatformException(InputImageConverterError, ImageFormat is not supported., null, null)

google_mlkit_face_detection: ^0.13.1
google_mlkit_commons: ^0.11.0
camera: ^0.11.2

_controller = CameraController(
_cameras![cameraIndex],
ResolutionPreset.high,
enableAudio: true,
imageFormatGroup: ImageFormatGroup.yuv420,
);

On pixel 9 Pro or Samsung s10+

Same as mine in QR and Barcode Scanners

google_mlkit_barcode_scanning: ^0.14.1

[darielkurt]

I fixed it by doing this

final inputImageFormat =
    Platform.isIOS ? InputImageFormat.bgra8888 : InputImageFormat.nv21;


final inputImageData = InputImageMetadata(
  size: size,
  rotation: imageRotation,
  format: inputImageFormat,
  bytesPerRow: bytesPerRow,
);

this is where I got the "fix"

try this code with google_mlkit_face_detection: ^0.13.1 and camera: ^0.11.2
without google_mlkit_commons , It works well for me. Pixel 7a & Samsung Tab A8

final format = Platform.isAndroid
        ? InputImageFormat.nv21
        : InputImageFormat.bgra8888;

final plane = image.planes.first;
    final WriteBuffer allBytes = WriteBuffer();
    for (final Plane plane in image.planes) {
      allBytes.putUint8List(plane.bytes);
    }
 final inputImage = InputImage.fromBytes(
      bytes: allBytes.done().buffer.asUint8List(),
      metadata: InputImageMetadata(
        size: Size(image.width.toDouble(), image.height.toDouble()),
        rotation: rotation,
        format: format, 
        bytesPerRow: plane.bytesPerRow, 
      ),
    );
