Beside needing to add WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE to your android/app/src/main/AndroidManifest.xml

You also need Runtime Request Permission, by using simple_permissions package:

import 'package:simple_permissions/simple_permissions.dart';

PermissionStatus permissionResult = await SimplePermissions.requestPermission(Permission. WriteExternalStorage);
if (permissionResult == PermissionStatus.authorized){
  // code of read or write file in external storage (SD card)
}

Note:

1. when running SimplePermissions.requestPermission for the First Time， app will popup a window, you MUST click ALLOW:

to give permission.

2. If you already clicked DENY, then uninstall debug app and re-debug it to install and fix this -> trigger the popup window and give you chance to click ALLOW.
