Implementation

Future<void> cancel() async {
  final BasicMessageChannel<Object?> channel = BasicMessageChannel<Object?>(
      'dev.flutter.pigeon.mapbox_maps_flutter.MapSnapshotter.cancel', codec,
      binaryMessenger: _binaryMessenger);
  final List<Object?>? replyList = await channel.send(null) 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;
  }
}
