iOS

If you need to implement screen capture on iOS, I have also developed two helpful plugins:

1. ReplayKit Launcher: A flutter plugin of the launcher used to open RPSystemBroadcastPickerView for iOS

2. Shared preferences with App Group: Shared preference supporting iOS App Group capability (using -[NSUserDefaults initWithSuiteName:])

Usage

To use this plugin, add media_projection_creator as a dependency in your pubspec.yaml file.

Example

• Flutter

int errorCode = await MediaProjectionCreator.createMediaProjection();
if (errorCode == MediaProjectionCreator.ERROR_CODE_SUCCEED) {
    print('createMediaProjection succeed');
}

• Android

public class MainActivity extends FlutterActivity {

    private static MediaProjection mediaProjection;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        /// Example: developers should call this method to set callback,
        /// when dart call `createMediaProjection`, it would be return a MediaProjection through this callback
        RequestMediaProjectionPermissionManager.getInstance().setRequestPermissionCallback(mediaProjectionCreatorCallback);

        /// Customize the media projection foreground notification style (available since Android Q)
        /// If not set, it will be the system default style
        RequestMediaProjectionPermissionManager.getInstance().setForegroundServiceNotificationStyle(R.mipmap.ic_launcher, "Screen is being captured");
    }

    private final MediaProjectionCreatorCallback mediaProjectionCreatorCallback = new MediaProjectionCreatorCallback() {

        @Override
        public void onMediaProjectionCreated(MediaProjection projection, int errorCode) {
            if (errorCode == RequestMediaProjectionPermissionManager.ERROR_CODE_SUCCEED) {
                Log.i("MEDIA_PROJECTION_CREATOR", "Create media projection succeeded!");
                mediaProjection = projection;
            } else if (errorCode == RequestMediaProjectionPermissionManager.ERROR_CODE_FAILED_USER_CANCELED) {
                Log.e("MEDIA_PROJECTION_CREATOR", "Create media projection failed because can not get permission");
            } else if (errorCode == RequestMediaProjectionPermissionManager.ERROR_CODE_FAILED_SYSTEM_VERSION_TOO_LOW) {
                Log.e("MEDIA_PROJECTION_CREATOR", "Create media projection failed because system api level is lower than 21");
            }
        }
    };
}

Please see the example app of this plugin for a full example.
