A small library that simplifies controls of your app such as page navigation.

Features

• Simplifies app controls such as "Navigator.push" to something easier to use.

Getting started

• Install the package via "flutter pub get app_controller".
• Import the library.
• init the controller in the app's initState function and set the page controller as the child of MaterialApp:

void initState() {
  super.initState();

  app_controller.init(
      refreshFn: setState,
      startPage: const HomePage(),
  );
}

MaterialApp(
  home: const app_controller.PageController(),
);

import 'package:flutter/material.dart';
import 'package:app_controller/app_controller.dart' as app_controller;

import 'page_home.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => MyAppState();
}

class MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();

    app_controller.init(
        refreshFn: setState,
        startPage: const HomePage(),
    );
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const app_controller.PageController(),
    );
  }
}

• You are ready to go.

Usage

Simplify an app control such as Navigator.push by using nav.openSubPage instead:

import 'package:flutter/material.dart';
import 'package:app_controller/app_controller_nav.dart' as nav;

class HomePage extends StatefulWidget {
  const HomePage({
    super.key,
  });

  @override
  State<HomePage> createState() => HomePageState();
}

class HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) =>
      Scaffold(
        body: Column(
          children: [
            const Text("Hello"),

            ElevatedButton(
              onPressed: () {
                nav.openSubPage(MenuPage());
              },
              child: const Text("Open Menu"),
            ),
          ],
        ),
      );
}
