推荐答案

我找到了解决方案.我创建了FAB按钮来更改我的位置"按钮

I found the solution. I create FAB button to change My Location button

GoogleMap(
        mapType: MapType.hybrid,
        initialCameraPosition: _kGooglePlex,
        onMapCreated: (GoogleMapController controller) {
          _controller.complete(controller);
        },
        myLocationEnabled: true,
      ),
      floatingActionButton: FloatingActionButton.extended(
        onPressed: _currentLocation,
        label: Text('My Location'),
        icon: Icon(Icons.location_on),
      ),
    );
  }

还要设置 _currentLocation 方法以调用我的位置

also, set the _currentLocation method to call my location

void _currentLocation() async {
   final GoogleMapController controller = await _controller.future;
   LocationData currentLocation;
   var location = new Location();
   try {
     currentLocation = await location.getLocation();
     } on Exception {
       currentLocation = null;
       }

    controller.animateCamera(CameraUpdate.newCameraPosition(
      CameraPosition(
        bearing: 0,
        target: LatLng(currentLocation.latitude, currentLocation.longitude),
        zoom: 17.0,
      ),
    ));
  }
