Simple exemple to use Module Provider

On main.dart, i will informed that the 'AppModule' is my root module, so the component returned from 'build' function inside the module will be showed.

import 'app_module.dart';

void main() {
	runApp(MaterialApp(
		title: 'Module Provider',
		theme: ThemeData(primarySwatch: Colors.blue,),
		home: AppModule()
	));
}

app_module.dart

import 'package:flutter/material.dart';

class AppModule extends Module {
	@override
	List<Inject<Service>> get services => [
		Inject((m, arg) => AppService(m)),
		Inject((m, arg) => AuthService(m, this.service<AppService>())),
	];

	@override
	List<Inject<Module>> get modules => [
		Inject((m, arg) => HomeModule(m)),
		Inject((m, arg) => RegistrationModule(m, arg)),
	];

	@override
	List<Inject<Component>> get components => [
		Inject((m, arg) => MainPage(m)),
		Inject((m, arg) => SplashScreenPage(m)),
	];

	AppModule() : super(null);

	@override
  	Widget build(BuildContext context) => component<MainPage>();
}
