Using two modules

This is a small project to demonstrate the power of this lib.

Use the common navigation of Flutter to create this project. The first file is main.dart when have all controll of navigation and FlutterInjections to provide a client Http for anywhere need this, this is a example of Global Injection.

main.dart

import 'package:dio/dio.dart';
import 'package:example/modules/home/widgets/home_alert_dialog/home_alert_dialog.dart';
import 'package:example/modules/splash/splash_injections.dart';
import 'package:flutter/material.dart';
import 'package:flutter_injections/flutter_injections.dart';

import 'modules/home/home_injections.dart';
import 'shared/services/custom_dio/custom_dio.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return FlutterInjections(
        injections: [
          Inject<Dio>((i) => CustomDio()),
        ],
        child: MaterialApp(
          title: 'Flutter Offline First',
          theme: ThemeData(
            primarySwatch: Colors.green,
          ),
          initialRoute: "/splash",
          routes: {
            "/splash": (context) => const SplashInjections(),
            "/home": (context) => const HomeInjections(),
            "/alert": (context) => const HomeAlertWidget()
          },
        ));
  }
}

Now to create a SplashInjections to add any dependencies this page use and pass the SplashPage on child parameter.

splash_injections.dart

import 'package:example/modules/splash/splash_page.dart';
import 'package:flutter/material.dart';
import 'package:flutter_injections/flutter_injections.dart';

import 'splash_controller.dart';

class SplashInjections extends StatelessWidget {
  const SplashInjections({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return FlutterInjectionsWidget(
      builder:(_) => const SplashPage(),
      injections: [
        Inject<SplashController>.singleton((i) => SplashController())
      ],
    );
  }
}

Now to create a HomeInjections to add any dependencies this page use and pass the HomePage on child parameter. This use a method find to recovery a global or parent injection and put on instance of the new object.

home_injections.dart'

import 'package:dio/dio.dart';
import 'package:flutter/material.dart';
import 'package:flutter_injections/flutter_injections.dart';

import 'home_controller.dart';
import 'home_page.dart';
import 'home_repository.dart';

class HomeInjections extends StatelessWidget {
  const HomeInjections({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return FlutterInjectionsWidget(injections: [
      Inject<HomeRepository>((i) => HomeRepository(client: i.find<Dio>())),
      Inject<HomeController>(
          (i) => HomeController(repository: i.find<HomeRepository>())),
    ], builder: (_) => const HomePage());
  }
}
