Android 10 (Q)

In Android 10, you need to add the Following Lines in AndroidManifest file:

<application
      android:requestLegacyExternalStorage="true"

Android 11

From Android 11, you need to manage permission within your app, if you want to write in different folders of external storage.

Steps

1. Add the following Lines in AndroidManifest file

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

2. Add device_info package to check android version
3. Check permission if app can manage external storage if its android 11 or greater Note: This is a runtime permission (might not show it in app info's permission section )

  var status = await Permission.manageExternalStorage.status;
      if (status!.isRestricted) {
        status = await Permission.manageExternalStorage.request();
      }

      if (status!.isDenied) {
        status = await Permission.manageExternalStorage.request();
      }
      if (status!.isPermanentlyDenied) {
        ScaffoldMessenger.of(context).showSnackBar(SnackBar(
          backgroundColor: Colors.green,
          content: Text('Please add permission for app to manage external storage'),
        ));
      }
