I am tring to upload file to flutter application but got user did not allowed external storage in application it is not asking for any permission

Answer 1

You must request storage permission first. add read external storage permission in android\app\src\main\AndroidManifest.xml

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

and request it by using permission_handler package.

example for the request:

final status = await Permission.storage.status;
final isGranted = status == PermissionStatus.granted;
if(!isGranted) {
  // alert user: storage permission is required.
}else{
  await pickFile();
}
