Flutter Google Maps errror - flutter

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(),

mapType: MapType.normal,
myLocationButtonEnabled: false,

}
