我找到了解决办法.我创建FAB按钮来更改我的位置按钮
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),
),
);
}
另外,设置_currentLocation
方法来调用我的位置
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,
),
));
}
