Flutter routing library that adds flexible routing options like parameters and clear route definitions.
To use this plugin, add flutter_router as a dependency in your pubspec.yaml file.
// Import package
import 'package:flutter_router/flutter_router.dart';runApp(MaterialApp(
onGenerateRoute: Router({
'/accounts/{id}': (context, match) => Account(id: match.parameters['id'),
'/': (context, match) => Index(),
}).get,
));
Router#get can throw if a route is not found. Because Navigator expects a return value of null if no route is found, it'd be good to wrap the function in a trycatch and return null so that onUnknownRoute can handle the error correctly.
Alternatively, we could provide a special case for a * or noMatch handler so that onGenerateRoute never actually fails to return a value.
Here's my widget and a stack trace for reference:
Navigator(
onUnknownRoute: (settings) {
return MaterialPageRoute(
fullscreenDialog: true,
builder: (context) {
return Container(color: Colors.red);
);
},
settings: settings);
},
initialRoute: "broken",
onGenerateRoute: Router({
"/": (context, match) => MainScreen(),
"/splash": (context, match) => SplashScreen(),
}).get,
),flutter: Bad state: No element
