Usage

After adding the permissions, you can request them in your Flutter app.

Obtain the instance

RequestPermission requestPermission = RequestPermission.instance;

Request the permissions

ElevatedButton(
    child: Text("request permissions"),
    onPressed: () {
        // 101 is the requestCode
        requestPermission.requestMultipleAndroidPermissions({
            "android.permission.CAMERA",
            "android.permission.CALL_PHONE",
            "android.permission.SYSTEM_ALERT_WINDOW"
        }, 101);
    },
),

Or request just one permission:

ElevatedButton(
    child: Text("request camera permission"),
    onPressed: () {
        // 27 is the requestCode
        requestPermission.requestAndroidPermission("android.permission.CAMERA", 27);
    },
),
ElevatedButton(
    child: Text("request call_phone permission"),
    onPressed: () {
        // 28 is the requestCode
        requestPermission.requestAndroidPermission("android.permission.CALL_PHONE", 28);
    },
),

Listen to the users choice

requestPermission.results.listen((event) {
   event.grantedPermissions.forEach((permission, isGranted) {
      if (isGranted) {
        print("The permission \"$permission\" has been granted!");
      } else {
        print("The permission \"$permission\" has NOT been granted!");
      }
    });
});
