Это AndroidManifest.xml

И я попытался использовать его, отображая его следующим образом

 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,

          ),

        ),

      );
  }
}
 

Я добавил <uses-library android:name="org.apache.http.legacy" android:required="false"/> в AndroidManifest.xml но все равно приложение по-прежнему выходит из строя. Может кто-нибудь мне помочь?

Это работает, если вы измените minSdkVersion на 24 в build.gradle. Пока не удалось выяснить причину.

Кстати, оно работает в java / android studio, даже если minSdkVersion равно 16.

Так что это может быть проблема с конфигурацией flutter.

попробуйте версию Gradle 3.5.0 и минимальный SDK 20

сработало для меня
