BFastUI - Introduction

State and architecture management library for flutter

Installation

Open your project's pubspec.yaml and add bfastui as a dependency:

dependencies:
  bfastui: any

You can also provide the git repository as source instead, to try out the newest features and fixes:

dependencies:
  bfastui:
    git:
      url: https://github.com/fahamutech/bfast-ui-flutter.git

Module

You organised your domain in your application in modules. Module is a top level abstraction of your application.

MainModule

This is the bootstrap module for your application. Is only defined once your application. You will required to implement initRoutes and initStates method

• initRoutes - You will add all routes of the pages your module will use

• initStates - You will add all states you will use in your module

class MyApp extends MainModuleAdapter{
  @override
  void initRoutes(String moduleName) {
      // TODO: implement initRoutes
    }
  
    @override
    void initStates(String moduleName) {
    // TODO: implement initStates
  }

}

ChildModule

This is the feature module to enclose your specific business logic. Your will required to impelement the following methods

• initRoutes - You will add all routes of the pages your module will use

• initStates - You will add all states you will use in your module

• moduleName - This will return your module name, name can be any String of your choice

class MyApp extends ChildModuleAdapter{
  @override
  void initRoutes(String moduleName) {
      // TODO: implement initRoutes
    }
  
    @override
    void initStates(String moduleName) {
    // TODO: implement initStates
  }

  @override
  String moduleName() {
    // TODO: implement moduleName
    return 'your-module-name';
  }

}

Page

Page is what your see presented by your mobile phone. i.e login page. Page belongs to a specific module and characterised with url to navigate to. Page can have one or more components which make the whole page functional. To create a page you extend BFastUIPage and you will required to implement build method which return a Widget represent that page.

• build(var args) - your must provide implementation for this method. args parameter your will use it to extract information of that page i.e url parameters. args has the following properties

    final Map<String, dynamic> params;
    final dynamic data;  
  

class MyPage extends PageAdapter{
  @override
  Widget build(var args) {
    // TODO: implement build
    throw UnimplementedError();
  }

}

State

State call information of the current view of your page ( s ). State is a ChangeNotifier class to be used with provider state management under the hood.

class MyState extends StateAdapter{
  
}

to notify listerner for changes your will just call notifyListeners() as you would in ChangeNotifier class.

Route

A Route carry information of where to navigate to in your application and whether to allow someone access or not. You can navigate to another Page or Module.

Route Guard

To create a route guard

class MyRouteAuthGuard extends RouterGuardAdapter{
  @override
  Future<bool> canActivate(String url) {
    // TODO: implement canActivate
    throw UnimplementedError();
  }
}

when canActivate resolve to true the page or a module someone navigate to will be activated otherwise will return to previous route if available

Example

class MyHomePage extends PageAdapter{
  @override
  Widget build(args) {
    return Scaffold(
      body: Container(
        color: Colors.red,
      ),
    );
  }

}

class MyState extends StateAdapter{
  int count = 0;

  increase(){
    count += 1;
    notifyListeners();
  }
   decrement(){
    count -= 1;
    notifyListeners();
  }
}

class MyAppModule extends MainModuleAdapter{
  @override
  void initRoutes(String moduleName) {
      BFastUI.navigation(moduleName: moduleName)
      .addRoute(RouterAdapter('/home', page: (content,args)=>MyHomePage()));

    }
  
    @override
    void initStates(String moduleName) {
      BFastUI
      .states(moduleName: moduleName)
      .addState((i) => MyState());
  }

}


void main(){
  runApp(
    BFastUI.module(module: MyAppModule(), component: MaterialApp(
        initialPath: '/home'
    )).start()
  );
}
