Flutter - Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null,

I am trying to use Hive database in my flutter project. In order to use hive db I will have to use path_provider package. I installed that too. but when I run the app again or restart it is neither running nor restarting and getting this error.

enter image description here

 Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

E/flutter (15905): #0
PathProviderApi.getApplicationDocumentsPath

ANDROID MANIFEST FILE PERMISSIONS

 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
   />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
  />

MY CODE

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final document = await getApplicationDocumentsDirectory(); // ERROR AT THIS LINE
  Hive.init(document.path);
  runApp(const MyApp());
}
Solution

  • Actually, I didn't put any uses-permission in Maneifest file to use Hive. Instead of Hive.init(), I would like to suggest to use Hive.initFlutter(). But without

    final document = await getApplicationDocumentsDirectory();

    inside initFlutter() method, these actions are already done by itself.

    Future<void> main() async {
 WidgetsFlutterBinding.ensureInitialized();
 Hive.initFlutter();
 runApp(const MyApp());
}
