Flutter Google Maps errror

Question

Im just building a google maps with flutter 2.8.1 and google_maps_flutter: ^2.1.4, everytime i save/hot reload it give me this error not always but quite often and im afraid this will cause big problem in future.

note: i cannot change the flutter and maps version because i have to use this version

throw PlatformException(code: errorCode, message: errorMessage as String?, details: errorDetails, stacktrace: errorStacktrace);

this is the full error code

@override
  dynamic decodeEnvelope(ByteData envelope) {
    // First byte is zero in success case, and non-zero otherwise.
    if (envelope.lengthInBytes == 0)
      throw const FormatException('Expected envelope, got nothing');
    final ReadBuffer buffer = ReadBuffer(envelope);
    if (buffer.getUint8() == 0)
      return messageCodec.readValue(buffer);
    final Object? errorCode = messageCodec.readValue(buffer);
    final Object? errorMessage = messageCodec.readValue(buffer);
    final Object? errorDetails = messageCodec.readValue(buffer);
    final String? errorStacktrace = (buffer.hasRemaining) ? messageCodec.readValue(buffer) as String? : null;
    if (errorCode is String && (errorMessage == null || errorMessage is String) && !buffer.hasRemaining)
      throw PlatformException(code: errorCode, message: errorMessage as String?, details: errorDetails, stacktrace: errorStacktrace);
    else
      throw const FormatException('Invalid envelope');
  }

this is my full code

class MapScreen extends StatefulWidget {
  const MapScreen({Key? key}) : super(key: key);

  @override
  State<MapScreen> createState() => _MapScreenState();
}

class _MapScreenState extends State<MapScreen> {
  late GoogleMapController mapController;

  final LatLng _center = const LatLng(45.521563, -122.677433);

  static const CameraPosition _initialCameraPosition = CameraPosition(
    target: LatLng(37.42796133580664, -122.085749655962),
    zoom: 14.4746,
  );

  @override
  void dispose() {
    // TODO: implement dispose
    super.dispose();
    mapController.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: _buildAppBarr(),
      floatingActionButton: _buildCustomFab(),
      body: GoogleMap(
        mapType: MapType.normal,
        myLocationButtonEnabled: false,
        zoomControlsEnabled: false,
        initialCameraPosition: _initialCameraPosition,
        onMapCreated: (controller) => mapController = controller,
      ),
    );
  }

}
