The brightest, hippest, coolest router for Flutter.

Version 1.6.0 (and higher) requires Flutter >= 1.12.0 and Dart >= 2.6.0. If you're running an older version of Flutter, use a version < 1.6.0.

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

Version compatability

See CHANGELOG for all breaking (and non-breaking) changes.

Getting started

You should ensure that you add the router as a dependency in your flutter project.

dependencies:
 fluro: "^1.6.3+2"

You can also reference the git repo directly if you want:

dependencies:
 fluro:
   git: git://github.com/fanhero/fluro.git

You should then run flutter packages upgrade or update your packages in IntelliJ.

Example Project

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

Setting up

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

final router = Router();

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, Object arguments) {
  return UsersScreen(params["id"][0]);
});

void defineRoutes(Router 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 the Router with the MaterialApp.onGenerateRoute parameter via the Router.generator function. 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);

Parameters vs. Arguments

The params is a convenient way to pass simple data (in a Map) just using the route.

In addition (/* since 1.5.0 */), you can pass any object instance as argument. This is useful if you need to pass more complex data.

// where `User` is defined class
var userModel = User(id: 1234, name: 'demo');

// using Fluro router
router.navigateTo(context, "/users/1234?action=edit", arguments: userModel);

// alternatively, you can still use the Navigator
Navigator.of(context).pushNamed("/users/1234?action=edit", arguments: userModel);
