takeru/fluro

Fluro is a Flutter routing library that adds flexible routing options like wildcards, named parameters and clear route definitions.

English | Português

The brightest, hippest, coolest router for Flutter.

Features

• Simple route navigation
• Function handlers (map to a function instead of a route)
• Wildcard parameter matching
• Querystring parameter parsing
• Common transitions built-in
• Simple custom transition creation
• Follows beta Flutter channel
• Null-safety

Example Project

There is a pretty sweet example project in the example folder. Check it out. Otherwise, keep reading to get up and running.

Getting started

First, you should define a new FluroRouter object by initializing it as such:

final router = FluroRouter();

It may be convenient for you to store the router globally/statically so that you can access the router in other areas in your application.

After instantiating the router, you will need to define your routes and your route handlers:

var usersHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
  return UsersScreen(params["id"][0]);
});

void defineRoutes(FluroRouter router) {
  router.define("/users/:id", handler: usersHandler);

  // it is also possible to define the route transition to use
  // router.define("users/:id", handler: usersHandler, transitionType: TransitionType.inFromLeft);
}

In the above example, the router will intercept a route such as /users/1234 and route the application to the UsersScreen passing the value 1234 as a parameter to that screen.

Navigating

You can use FluroRouter with the MaterialApp.onGenerateRoute parameter via FluroRouter.generator. To do so, pass the function reference to the onGenerate parameter like: onGenerateRoute: router.generator.

You can then use Navigator.push and the flutter routing mechanism will match the routes for you.

You can also manually push to a route yourself. To do so:

router.navigateTo(context, "/users/1234", transition: TransitionType.fadeIn);

Class arguments

Don't want to use strings for params? No worries.

After pushing a route with a custom RouteSettings you can use the BuildContext.settings extension to extract the settings. Typically this would be done in Handler.handlerFunc so you can pass RouteSettings.arguments to your screen widgets.

/// Push a route with custom RouteSettings if you don't want to use path params
FluroRouter.appRouter.navigateTo(
  context,
  'home',
  routeSettings: RouteSettings(
    arguments: MyArgumentsDataClass('foo!'),
  ),
);

/// Extract the arguments using [BuildContext.settings.arguments] or [BuildContext.arguments] for short
var homeHandler = Handler(
  handlerFunc: (context, params) {
    final args = context.settings.arguments as MyArgumentsDataClass;

    return HomeComponent(args);
  },
);
