class ShowMapPage extends BasePage {
  ShowMapPage(String title, String subTitle) : super(title, subTitle);
  @override
  Widget build(BuildContext context) {
    return _ShowMapPageBody();
  }
}

class _ShowMapPageBody extends StatefulWidget {
  @override
  State<StatefulWidget> createState() => _ShowMapPageState();
}

class _ShowMapPageState extends State<_ShowMapPageBody> {
  static final CameraPosition _kInitialPosition = const CameraPosition(
    target: LatLng(39.909187, 116.397451),
    zoom: 10.0,

      ),
    );
  }

  AMapController _mapController;
  void onMapCreated(AMapController controller) {
    setState(() {
      _mapController = controller;
      getApprovalNumber();
    });
  }

  /// Get the review number
  void  getApprovalNumber () the async {
     // general map plan approval number 
    String mapContentApprovalNumber = 
        the await _mapController ? . getMapContentApprovalNumber ();
     // satellite map plan approval number 
    String satelliteImageApprovalNumber = 
        the await _mapController ? . getSatelliteImageApprovalNumber ();
     setState (() {
       IF ( null  != mapContentApprovalNumber) {
        _approvalNumberWidget.add(Text(mapContentApprovalNumber));
      }
      if (null != satelliteImageApprovalNumber) {
        _approvalNumberWidget.add(Text(satelliteImageApprovalNumber));
      }
    });
    print ( 'Map review number (normal map): $ mapContentApprovalNumber ' );
     print ( 'Map review number (satellite map): $ satelliteImageApprovalNumber ' );
  }
}

Known issues:

1. When the Flutter plug-in is on the iOS side, when the MapView is destroyed, it will trigger the alarm of the Main Thread Checker with a certain probability. After comparison tests, it is confirmed that it is caused by a Flutter bug; https://github.com/flutter/flutter/issues/68490 (compare 1.25.0 -8.1.pre version has been fixed. According to github issues, there are feedback from other developers that 1.24.0-6.0.pre has been fixed; this issue depends on Flutter upgrade and repair)
