Router Management #
A plugin that wraps the Navigator 2.0 with a syntax sugar for Flutter Developers
Getting Started #

Installing the package manually:

Open the pubspec.yaml file, search for dependencies: and write this below:
dependencies:
router_management: ^3.1.0

Usage #

Create a NavigationWidgetMixin that builds a Router for example:

class App extends StatelessWidget with NavigationWidgetMixin {
App({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return MaterialApp.router(
routeInformationParser: routeInformationParser,
routerDelegate: routerDelegate,
title: 'Router Management Example',
localizationsDelegates: GlobalMaterialLocalizations.delegates,
);
}
}
copied to clipboard

Or

class App extends StatefulWidget with NavigationWidgetMixin {
App({Key? key}) : super(key: key);

@override
_AppState createState() => _AppState();
}

class _AppState extends State<App> {
@override
Widget build(BuildContext context) {
return MaterialApp.router(
routeInformationParser: widget.routeInformationParser,
routerDelegate: widget.routerDelegate,
title: 'Router Management Example',
localizationsDelegates: GlobalMaterialLocalizations.delegates,
);
}
}
copied to clipboard

Create a Widget that represents a page for example:

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

// Declare the path as constant
static const path = '/home/:name';

// Declare the name as constant
static const name = 'Home';

@override
Widget build(BuildContext context) {
final arguments = context.arguments; // Get the page's arguments

return Scaffold(
body: Center(
child: Text(
'Welcome ${arguments.params['name']}',
style: const TextStyle(fontSize: 32, color: Colors.black),
),
),
);
}
}
copied to clipboard

Implements the NavigationRouter into the void main() method for example:

void main() {
runApp(NavigationRouter(
child: App(), // The NavigationWidgetMixin that builds a Router
pages: [
NavigationPage(
path: SplashScreen.path,
builder: () => const SplashScreen(),
name: SplashScreen.name,
),
NavigationPage(
path: HomeScreen.path,
builder: () => const HomeScreen(),
name: HomeScreen.name,
),
], // The pages
initialPage: SplashScreen.path, // The initial page's path. Defaults to "/"
unknownPage: NavigationPage(
path: NotFound.path,
builder: () => const NotFound(),
name: NotFound.name,
), // A page that is built when an unknown path is passed
));
}
copied to clipboard

Use the Navigation instance from NavigationService.instance to controls the Navigator 2.0 with Imperative methods for example:


NavigatorService.instance.pushReplacement('/home/John Doe');
or using Router Management extensions on BuildContext
BuildContext.navigator.pushReplacement('/home/John Doe');


To get the path's arguments use the extension on BuildContext for example:

@override
Widget build(BuildContext context) {
final arguments = context.arguments;
...

Keep coding :)

APIS #
The Router Management has many APIS to ensure that you can handle the Navigator 2.0
NavigationRouter
Is the widget core for Navigator 2.0 implementation

Props




Name
Description
Required




child
Is used to build a Router to handle the Navigator 2.0 implementation
true


pages
Is used to create pages that can be accessed by the Navigator 2.0
true


initialPage
Is used to render the page that has the same path. If the PageWidget.build returns a router without a RouteInformationProvider it will not work correctly. Defaults to "/"
false


navigatorObservers
Is used to observe the Navigator 2.0 when navigating between screens. Defaults to List.empty()
false


useHash
If it is true then will be used the default url strategy that is a path with hash, for example: flutterexample.dev/#/path/to/screen, else will be flutterexample.dev/path/to/screen. Defaults to false
false


restorationScopeId
Is used to save and restore the navigator 2.0 state, if it is null then the state will not be saved. Defaults to null
false


unknownPage
Is used to create an unknown page with the given path. Defaults to null
false


transitionDuration
Is used to controls the animation transition. Defaults to Duration(milliseconds: 400)
false


transitionsBuilder
Is used to build a global custom animation transition when navigating to another page. Defaults: If the platform is web then will not has any transition else will be null
false




Static Methods




Name
Description

NavigationRouterGuard
Is used to validate the page, if the page can't be activated, then will be redirected to another
page.

Props

Description
Required




child
Is used to build the page when it can be activated

true


placeholder
Is used to build a placeholder while is activating. Defaults to SizedBox.shrink()



pathToRedirectOnInvalidate
Is used to redirect to a page when redirectToUnknownPageOnInvalidate is false or if was not set an unknown page in the NavigationRouter. Defaults to "/"
false


redirectToUnknownPageOnInvalidate
Is used to redirect to the unknown page, if it was not set or the value is false, then will be redirect using pathToRedirectOnInvalidate. Defaults to true
false

false


transitionDuration
Is used to controls the animation transition. Defaults to NavigationRouter.transitionDuration
false


validators
is used to controls the page's activation when it must has more than the basics arguments like an id or something else, if it returns false then the page will be redirect to the initial page or use the Navigation to redirect to another page. Defaults to List.empty()
