This is a pattern I came up with when I was working on a fairly large one person app (25k LOC, legal/regulation calculator, lots of unit testing). It is very simple and very effective.

The short version is you have a RootStore that listens to all of it's child stores. Each store has an async initState method and a dispose method. Make observer mixins for platform channel related items like App Lifecycle, Geolocation, Geofencing that add more lifecycle methods to these stores and manage their own initState/dispose.

I realize that a gist is going to look like a bit of a cluster for something of this nature but I bet if you pull it all down into a project and start playing around with it you'll really enjoy it. Especially now that provider has context.select.

Here's an example of my folder structure in lib/features as a bit of a bonus

	# .github/workflows/dart.yml

	name: build

	on:
	push:
	branches: [master]
	pull_request:
	branches: [master]

	import 'dart:convert';
	import 'dart:io';

	class Database {
	/// A simple JSON file database
	Database(String path) : file = File(path);

	final File file;

	var _store = <String, dynamic>{};

	main() {
	BuildContext context;

	final router = NavigationService(context);

	return MaterialApp(
	onGenerateRoute: (settings) => router.handleGenerateRoute(
	settings,
	routes: {
	'/': (params, context) => HomeView(),

	import 'dart:convert';

	void main() {
	final foo = Foo('bar');
	print(foo);
	print(foo.foo);
	print(jsonEncode(foo));
	print(jsonEncode([foo, foo, foo]));

	import 'package:flutter/material.dart';
	import 'package:flutter_portal/flutter_portal.dart';

	class MyApp extends StatelessWidget {
	static const title = 'Spike Overlay TextField';

	/// An example of operations you can do with control flow collections.
	///
	/// They make it very easy to do map, filter, and spread operations, all
	/// while retaining the base class of [List<T>], [Set<T>], and [Map<K,V>]
	void main() {
	final source = [1, 2, 3, null, 4, 5, null];

	/// List control flow, map & filter
	final myList = [
	for (var number in source)

	VERSION = 1.0.0
	BUILD = 8
	CHANGELOG = Added item counts and a celebration when a list is completed.

	.PHONY: clean test build distribute

	clean:
	flutter clean
	flutter pub get
	pod repo update

	data class User {
	String name,

	data class Manager extends User {

	abstract class Detailed {
	String get details;

	void main() {
	final a = 4;

	final truthy = {
	Case(a % 2 == 0): "even",
	Case(a == 3): "three",
	Case(a >= 4): "four or more",
	}.build(
	fallback: 'less than two',
	);
