只有在我的 huawei p10+ 上测试 Flutter 应用时才会出现此错误。我的应用程序在警报对话框上加载 googlemap。地图可以加载几次，然后随机失败。但我注意到 Googlemap 在失败时无法加载到 alertdialog 容器中。这是我的代码：

  _loadMapDialog() {
    try {
      if (_currentPosition.latitude == null) {
        Toast.show("Location not available. Please wait...", context,
            duration: Toast.LENGTH_LONG, gravity: Toast.BOTTOM);
        _getLocation(); //_getCurrentLocation();
        return;
      }
      _controller = Completer();
      _userpos = CameraPosition(
        target: LatLng(latitude, longitude),
        zoom: 14.4746,
      );

      markers.add(Marker(
          markerId: markerId1,
          position: LatLng(latitude, longitude),
          infoWindow: InfoWindow(
            title: 'Current Location',
            snippet: 'Delivery Location',
          )));

      showDialog(
        context: context,
        builder: (context) {
          return StatefulBuilder(
            builder: (context, newSetState) {
              return AlertDialog(
                shape: RoundedRectangleBorder(
                    borderRadius: BorderRadius.all(Radius.circular(20.0))),
                title: Text("Select Your Location"),
                titlePadding: EdgeInsets.all(5),
                //content: Text(curaddress),
                actions: <Widget>[
                  Text(curaddress),
                  Container(
                    height: screenHeight / 2 ?? 600,
                    width: screenWidth ?? 360,
                    child: GoogleMap(
                        mapType: MapType.normal,
                        initialCameraPosition: _userpos,
                        markers: markers.toSet(),
                        onMapCreated: (controller) {
                          _controller.complete(controller);
                        },
                        onTap: (newLatLng) {
                          _loadLoc(newLatLng, newSetState);
                        }),
                  ),
                  MaterialButton(
                    shape: RoundedRectangleBorder(
                        borderRadius: BorderRadius.circular(20.0)),
                    //minWidth: 200,
                    height: 30,
                    child: Text('Close'),
                    color: Colors.blue[500],
                    textColor: Colors.white,
                    elevation: 10,
                    onPressed: () =>
                        {markers.clear(), Navigator.of(context).pop(false)},
                  ),
                ],
              );
            },
          );
        },
      );
    } catch (e) {
      print(e);
      return;
    }
  }

调试控制台产生以下错误

在华为手机以外的不同设备上测试相同的代码似乎工作得很好。如果此错误似乎与设备相关，是否有任何解决方法。

华为不支持谷歌地图。您必须切换到另一个地图提供商，例如。https://pub.dev/packages/huawei_map
