Fllutter GoogleMap ZoomControl位置

Question

问题是缩放控件。我可以看到显示缩放控件出现，但我想更改Zoomcontrols的位置，以显示在右侧。是否可以更改Zoom控件的位置。

我没有找到任何解决方案，因此我创建了自定义缩放控件，并使用地图控制器将其添加到地图上。

Positioned(
      top: 100,
      left: 5,
      child: Card(
        elevation: 2,
        child: Container(
          color: Color(0xFFFAFAFA),
          width: 40,
          height: 100,
          child: Column(
            children: <Widget>[
              IconButton(
                  icon: Icon(Icons.add),
                  onPressed: () async {
                    var currentZoomLevel = await _controller.getZoomLevel();

                    currentZoomLevel = currentZoomLevel + 2;
                    _controller.animateCamera(
                      CameraUpdate.newCameraPosition(
                        CameraPosition(
                          target: locationCoords,
                          zoom: currentZoomLevel,
                        ),
                      ),
                    );
                  }),
              SizedBox(height: 2),
              IconButton(
                  icon: Icon(Icons.remove),
                  onPressed: () async {
                    var currentZoomLevel = await _controller.getZoomLevel();
                    currentZoomLevel = currentZoomLevel - 2;
                    if (currentZoomLevel < 0) currentZoomLevel = 0;
                    _controller.animateCamera(
                      CameraUpdate.newCameraPosition(
                        CameraPosition(
                          target: locationCoords,
                          zoom: currentZoomLevel,
                        ),
                      ),
                    );
                  }),
            ],
          ),
        ),
      ),
    );

在googlemap（）小部件中添加填充选项

GoogleMap(
               initialCameraPosition: CameraPosition(
               target: _locationCoords, zoom: 12.0),
               markers: Set.from(allMarkers),
               onMapCreated: mapCreated,
               zoomControlsEnabled: true,
               zoomGesturesEnabled: true,
               scrollGesturesEnabled: true,
               compassEnabled: true,
               padding: EdgeInsets.only(
                 bottom:MediaQuery.of(context).size.height*0.25),
         )

PADDING：EDGEINSETS.ONLY（底部：MediaQuery.of（上下文）.Size.Height*0.25），

您还可以使用AnimateCamera方法使用CameraupDate类，例如：

  void zoomIn() async {
    final controller = await _controller.future;
    final zoom = await controller.getZoomLevel();
    controller.animateCamera(CameraUpdate.zoomTo(zoom + 1));
  }

  void zoomOut() async {
    final controller = await _controller.future;
    final zoom = await controller.getZoomLevel();
    controller.animateCamera(CameraUpdate.zoomTo(zoom - 1));
  }
