setMetadata method

Future<void> setMetadata(
  1. Uint8List arg_metadata
)

Sets arbitrary binary region metadata for the region.

Note that this setter is asynchronous and the given metadata is applied only after the resulting callback is invoked with no error.

@param metadata The metadata associated with the region. @param callback Called once the request is complete or an error occurred.

Implementation

Future<void> setMetadata(Uint8List arg_metadata) async {
  final BasicMessageChannel<Object?> channel = BasicMessageChannel<Object?>(
      'dev.flutter.pigeon.mapbox_maps_flutter.OfflineRegion.setMetadata',
      codec,
      binaryMessenger: _binaryMessenger);
  final List<Object?>? replyList =
      await channel.send(<Object?>[arg_metadata]) as List<Object?>?;
  if (replyList == null) {
    throw PlatformException(
      code: 'channel-error',
      message: 'Unable to establish connection on channel.',
    );
  } else if (replyList.length > 1) {
    throw PlatformException(
      code: replyList[0]! as String,
      message: replyList[1] as String?,
      details: replyList[2],
    );
  } else {
    return;
  }
