Step 2:

Go to project root and execute the following command in console to get the required dependencies:

flutter pub get 

Step 3:

This project uses inject library that works with code generation, execute the following command to generate files:

flutter packages pub run build_runner build --delete-conflicting-outputs

or watch command in order to keep the source code synced automatically:

flutter packages pub run build_runner watch

Hide Generated Files

In-order to hide generated files, navigate to Android Studio -> Preferences -> Editor -> File Types and paste the below lines under ignore files and folders section:

*.inject.summary;*.inject.dart;*.g.dart;

In Visual Studio Code, navigate to Preferences -> Settings and search for Files:Exclude. Add the following patterns:

**/*.inject.summary
**/*.inject.dart
**/*.g.dart

Folder Structure

Here is the core folder structure which flutter provides.

flutter-app/
|- android
|- build
|- ios
|- lib
|- test

Here is the folder structure we have been using in this project

lib/
|- constants/
|- data/
|- stores/
|- ui/
|- utils/
|- widgets/
|- main.dart
|- routes.dart

Now, lets dive into the lib folder which has the main code for the application.

1- constants - All the application level constants are defined in this directory with-in their respective files. This directory contains the constants for `theme`, `dimentions`, `api endpoints`, `preferences` and `strings`.
2- data - Contains the data layer of your project, includes directories for local, network and shared pref/cache.
3- stores - Contains store(s) for state-management of your application, to connect the reactive data of your application with the UI. 
4- ui — Contains all the ui of your project, contains sub directory for each screen.
5- util — Contains the utilities/common functions of your application.
6- widgets — Contains the common widgets for your applications. For example, Button, TextField etc.
7- routes.dart — This file contains all the routes for your application.
8- main.dart - This is the starting point of the application. All the application level configurations are defined in this file i.e, theme, routes, title, orientation etc.

Constants

This directory contains all the application level constants. A separate file is created for each type as shown in example below:

constants/
|- app_theme.dart
|- dimens.dart
|- endpoints.dart
|- preferences.dart
|- strings.dart

Data

All the business logic of the application will go into this directory, it represents the data layer of the application. It is sub-divided into three directories local, network and sharedperf, each containing the domain specific logic. Since each layer exists independently, that makes it easier to unit test. The communication between UI and data layer is handled by using central repository.

data/
|- local/
    |- constants/
    |- datasources/
    |- app_database.dart
   
|- network/
    |- constants/
    |- exceptions/
    |- rest_client.dart
    
|- sharedpref
    |- constants/
    |- shared_preference_helper.dart
    
|- repository.dart

Stores

The store is where all the application state lives in flutter. The Store is basically a widget that stands at the top of the widget tree and passes it's data down using special methods. In-case of multiple stores, a separate folder for each store is created as shown in the example below:

stores/
|- login/
    |- login_store.dart
    |- form_validator.dart

UI

This directory contains all the ui of the application. Each screen is located in a separate folder making it easy to combine group of files related to that particular screen. All the screen specific widgets will be placed in widgets directory as shown in the example below:

ui/
|- login
   |- login_screen.dart
   |- widgets
      |- login_form.dart
      |- login_button.dart

Utils

Contains the common file(s) and utilities used in a project. The folder structure is as follows:

utils/
|- encryption
   |- xxtea.dart
|- date
  |- date_time.dart

Widgets

Contains the common widgets that are shared across multiple screens. For example, Button, TextField etc.

widgets/
|- app_icon_widget.dart
|- empty_app_bar.dart
|- progress_indicator.dart

Routes

This file contains all the routes for the application.

import 'package:flutter/material.dart';

import 'ui/home/home.dart';
import 'ui/login/login.dart';
import 'ui/splash/splash.dart';

class Routes {
  Routes._();

  //static variables
  static const String splash = '/splash';
  static const String login = '/login';
  static const String home = '/home';

  static final routes = <String, WidgetBuilder>{
    splash: (BuildContext context) => SplashScreen(),
    login: (BuildContext context) => LoginScreen(),
    home: (BuildContext context) => HomeScreen(),
  };
}

Main

This is the starting point of the application. All the application level configurations are defined in this file i.e, theme, routes, title, orientation etc.

import 'package:boilerplate/routes.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

import 'constants/app_theme.dart';
import 'constants/strings.dart';
import 'ui/splash/splash.dart';

void main() {
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown,
    DeviceOrientation.landscapeRight,
    DeviceOrientation.landscapeLeft,
  ]).then((_) {
    runApp(MyApp());
  });
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: Strings.appName,
      theme: themeData,
      routes: Routes.routes,
      home: SplashScreen(),
    );
  }
}
