+
+GoRouter Enhancements for Flutter
+
+This package provides a set of utilities to help you use the [GoRouter](https://pub.dev/packages/go_router) package.
+
+## Features
+
+* PageProtection extension to add a protection to a page
+* currentRoute method to get the current route anywhere in the app
+* GoRouterRefreshStream to refresh the router when needed
+* RouteBase flattenization to get a list of all the routes in the router
+
+## Usage
+
+If you want to protect a page, you can use the PageProtection extension:
+
+```dart
+GoRoute(
+ path: '/sign_in',
+ ...
+)..setPublic(),
+```
+
+If you want to get the current route, you can use the currentRoute method:
+
+```dart
+final route = GoRouter.of(context).currentRoute;
+// or
+final route = context.currentRoute;
+```
+
+If you want to refresh the router, you can use the GoRouterRefreshStream:
+
+```dart
+GoRouterRefreshStream(
+  context.read<AuthenticationCubit<Session>>().stream,
+)
+```
+
+If you want to get a list of all the routes in the router, you can use the RouteBase flattenization:
+
+```dart
+final routes = GoRouter.of(context).flattenedRoutes;
+```
