FlutterNavigator

FlutterNavigator is a dart library for dealing with the Navigator API without a build context. This package wraps the NavigatorKey and provides a cleaner service for navigating without context in your flutter application.

Installation

Use the pubspec.yaml file to install the dependency.

flutter_navigator: ^0.1.2

Usage

Adding the Navigator Key

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Navigator Key',
      navigatorKey: FlutterNavigator().navigatorKey,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const PageOne(),
    );
  }
}

You need to provide the navigator key to your MaterialApp as that is how the service will communicate with the navigator state without the build context.

Using the FlutterNavigator

final FlutterNavigator _flutterNavigator = FlutterNavigator();

_flutterNavigator.push(PageTwo.route());

The FlutterNavigator is a singleton service so it will always keep the same instance throughout the lifetime of the application. You can call the Navigator API methods through the service (like 'push', 'pop', 'pushAndRemoveUntil', etc)... It's that simple!

Using the FlutterNavigator Observers

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Observers',
      navigatorKey: FlutterNavigator().navigatorKey,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      navigatorObservers: [
        FlutterNavigator().routeObserver,
      ],
      home: const PageOne(),
    );
  }
}

As with the navigator key, you can use the route observer provided by the service and this can be accessed throughout the application.

Creating your own implementation

class CustomFlutterNavigator implements IFlutterNavigator

To create your own implementation, all you need to do is implement the interface IFlutterNavigator and provide all the needed methods and properties.
