flutter-错误：无法将类型“ PermissionStatus”的值分配给类型“ bool”的变量

Question

最近更新频繁后出现错误消息（我三个月都没有更新代码，但是上次构建成功）。

lib / src / blocs / home / home_bloc.dart：141：23：错误：不能将类型为“ PermissionStatus”的值分配给类型为“ bool”的变量。 < / p>

• “ PermissionStatus”来自“ package：location / location.dart”（“ ../ programs / flutter / .pub-cache / hosted / pub.dartlang.org / location-2.5.4 / lib / location.dart'）。

  _permission =等待_locationService.requestPermission（）;

有什么想法吗？

Answer 1

https://pub.dev/packages/location_permissions

import 'package:location_permissions/location_permissions.dart';
PermissionStatus permissionStatus = await LocationPermissions().requestPermissions();

PermissionStatus permission = await LocationPermissions().checkPermissionStatus();

Answer 2

尝试

PermissionStatus permission  =  await location.hasPermission();


    if(permission==PermissionStatus.GRANTED){
      return location.getLocation();
    }else{
      location.requestPermission();
    }

Answer 3

  if (result == PermissionStatus.GRANTED) {
    location.onLocationChanged().listen((locationData) {
      if (locationData != null) {
        _locationController.add(UserLocation(
          latitude: locationData.latitude,
          longitude: locationData.longitude,
        ));
      }
    });
  }
