flutter 中的 showModalBottomSheet 有多接近？

Question

class _LoginPageState extends State<LoginPage> with WidgetsBindingObserver{ PersistentBottomSheetController controller; final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>(); @override void initState() { super.initState(); requestPermission(Permission.location); getIdentifierState(); WidgetsBinding.instance.addObserver(this); } Future<void> requestPermission(Permission permission) async { final status = await permission.request(); if(status != PermissionStatus.granted){ _showModalBottomSheet(context); }else{ // how close _showModalBottomSheet Position position = await Geolocator().getCurrentPosition(desiredAccuracy: LocationAccuracy.high); print(position.latitude); print(position.longitude); bloc.coordinate(position.latitude.toString() + position.longitude.toString()); } }

Answer 1

When calling your method, pass the parameter context to be used during modal closing as follow:

Navigator.of(context).pop();

Answer 2

within the sheet add a button with the following action

    ElevatedButton(onPressed: () {
                        Navigator.of(context).pop();
                      },)
