Fix exif rotation for flutter

Flutter plugin that fixes the picture orientation for some devices. In some devices the exif data shows picture in landscape mode when they're actually in portrait. This plugin fixes the orientation for pictures taken with those devices.

Every version of Android is supported. iOS implemented by @Bhagatcliffex and currently supported

Android

Add this in your AndroidManifest.xml (you don't need these permissions in case when you manipulate files from internal storage only (file are stored inside the app's directory ( /data/data/{your package}/ )) )

Example

  @override
  _MyAppState createState() => _MyAppState();
}

/// The class with the scaffold
class _MyAppState extends State<MyApp> {
  File _image;
  final picker = ImagePicker();

  Future getImage() async {
    final image = await picker.getImage(source: ImageSource.gallery);
    if (image != null && image.path != null) {
      File rotatedImage =
          await FlutterExifRotation.rotateImage(path: image.path);

      if (image != null) {
        setState(() {
          _image = rotatedImage;
        });
      }
    }
  }
