How can I change IOS and Android settings in Flutter? - flutter

Question

I'm working on a drawing app that uses Apple Pad and Stylus.
In order to use stylus smoothly in this app, it must disable scribble option in the stylus setting.
If so, how do I access the settings in the IOS or Android on the setting and change the settings options?
And can I check what the current settings value are before I access setting? For example, can I check if the scribble in stylus setting is enabled?

Check out this package:
https://pub.dev/packages/app_settings/example
import 'dart:async';
import 'package:app_settings/app_settings.dart';
import 'package:flutter/material.dart';
/// Main method to return runApp.
void main() => runApp(MyApp());
/// This is the main app stateful widget.
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
/// This is the app state.
class _MyAppState extends State<MyApp> {
#override
void initState() {
/// Call out to intialize platform state.
initPlatformState();
super.initState();
}
/// Initialize platform state.
Future<void> initPlatformState() async {
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
}
/// Widget build method to return MaterailApp.
