这是 AndroidManifest.xml

我尝试使用它来显示它
class _MyHomePageState extends State<MyHomePage> {
Completer<GoogleMapController> _controller = Completer();
static const LatLng _center = const LatLng(45.521563, -122.677433);
void _onMapCreated(GoogleMapController controller) {
_controller.complete(controller);
}
@override
Widget build(BuildContext context) {
// This method is rerun every time setState is called, for instance as done
// by the _incrementCounter method above.
//
// The Flutter framework has been optimized to make rerunning build methods
// fast, so that you can just rebuild anything that needs updating rather
// than having to individually change instances of widgets.
return Scaffold(
appBar: AppBar(
title: Text('Maps Sample App'),
backgroundColor: Colors.green[700],
),
body: GoogleMap(
onMapCreated: _onMapCreated,
initialCameraPosition: CameraPosition(
target: _center,
zoom: 11.0,
),
),
);
}
}
我在 AndroidManifest.xml 中添加了<uses-library android:name="org.apache.http.legacy" android:required="false"/>，但应用程序仍然崩溃。有人可以帮帮我吗？
【问题讨论】：
-
我正在使用
google_maps_flutter: ^1.0.6。谢谢 -
可能与这个github.com/flutter/flutter/issues/72185（？）有关
-
谢谢我去看看
