playx_navigation 0.0.1

Playx Navigation is a Flutter package that enhances app navigation with advanced features like route lifecycle management, custom transitions, and flexible configuration.

Playx Navigation

Playx Navigation is a robust and flexible Flutter package that enhances the navigation capabilities of your Flutter applications. It builds on the go_router package to provide powerful features like route-specific lifecycle management with bindings, extensive route configuration options, and custom page transitions. With Playx Navigation, you can create a highly modular and maintainable navigation system for your apps.

Features

• Route Bindings: Attach custom logic to specific routes, handling lifecycle events such as entering or exiting a route.
• Advanced Route Configuration: Fine-tune the behavior of your routes with extensive configuration options, including custom transitions, modal behavior, and state management.
• Route Management: Easily navigate to routes, replace routes, and handle navigation stacks without the need for buildcontext.
• Custom Page Transitions: Use predefined transitions or create your own to enhance the user experience.

Installation

Add Playx Navigation to your pubspec.yaml:

dependencies:
  playx_navigation: ^0.0.1 

Then, run:

flutter pub get

Setup

Step 1: Define Your Routes (Optional)

You can optionally define your route names and paths for easier management:

abstract class Routes {
  static const home = 'home';
  static const products = 'products';
  static const details = 'productDetails';
}

abstract class Paths {
  static const home = '/home';
  static const products = '/products';
  static const details = ':id';
}

Step 2: Create Your GoRouter Instance

Use the PlayxRoute to define your app's navigation structure:

final router = GoRouter(
  initialLocation: Paths.home,
  debugLogDiagnostics: true,
  routes: [
    PlayxRoute(
      path: Paths.home,
      name: Routes.home,
      builder: (context, state) => const HomePage(),
      binding: HomeBinding(),
    ),
    PlayxRoute(
      path: Paths.products,
      name: Routes.products,
      builder: (context, state) => ProductsPage(),
      binding: ProductsBinding(),
      routes: [
        PlayxRoute(
          path: Paths.details,
          name: Routes.details,
          builder: (context, state) => 
            ProductDetailsPage(product: state.extra as Product),
          binding: DetailsBinding(),
        ),
      ],
    ),
  ],
);

Step 3: Initialize PlayxNavigationBuilder

Wrap your MaterialApp or CupertionApp in PlayxNavigationBuilder and pass the router instance to it to enable Playx Navigation and manage route changes:

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return PlayxNavigationBuilder(
      router: router,
      builder: (context) {
        return MaterialApp.router(
          title: 'Playx',
          theme: ThemeData(
            colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
          ),
          routerDelegate: router.routerDelegate,
          routeInformationParser: router.routeInformationParser,
          routeInformationProvider: router.routeInformationProvider,
          backButtonDispatcher: router.backButtonDispatcher,
        );
      });
  }
}

PlayxNavigationBuilder simplifies the setup process by providing a centralized way to configure and manage routes, bindings, and other navigation-related settings.

PlayxNavigation Methods and Utilities

The PlayxNavigation class offers a variety of static methods for managing navigation within your Flutter application using the GoRouter package. Before utilizing any of these methods, ensure that PlayxNavigation has been initialized by calling PlayxNavigation.boot() or by including the PlayxNavigationBuilder widget in your widget tree.

Initialization

Before using any navigation methods, initialize PlayxNavigation:

PlayxNavigation.boot(router: yourGoRouterInstance);

Alternatively, use PlayxNavigationBuilder to automatically initialize the navigation system:

return PlayxNavigationBuilder(
  router: router,
  builder: (context) {
    return MaterialApp.router(
      routerDelegate: router.routerDelegate,
      routeInformationParser: router.routeInformationParser,
    );
  });

Methods Overview

• Navigating to Routes No need of BuildContext as you can call the navigation methods from anywhere.

  • to: Pushes a new route onto the navigation stack.

    await PlayxNavigation.to('/details', extra: {'id': 1});
    

  • offAll: Replaces all previous routes in the stack with a new route.

    await PlayxNavigation.offAll('/home', extra: {'clearHistory': true});
    

  • offAndTo: Replaces the current route with a new route.

    await PlayxNavigation.offAndTo('/profile', extra: {'userId': 123});
    

• Named Route Navigation

  • `toNamed: Pushes a named route onto the navigation stack.

    await PlayxNavigation.toNamed('details', pathParameters: {'id': '1'});
    

  • offAllNamed: Replaces all previous routes in the stack with a named route.

    await PlayxNavigation.offAllNamed('home');
    

  • offAndToNamed: Replaces the current route with a named route.

      await PlayxNavigation.offAndToNamed('profile', pathParameters: {'userId': '123'});
    

• Navigation Control

  • goToBranch: Navigates to the current location of the branch at the provided index of StatefulShellRoute.

  • pop([T? result]): Pops the top-most route off the navigation stack.

    PlayxNavigation.pop();`
    

  • canPop(): Returns true if there are routes in the navigation stack that can be popped.

    if (PlayxNavigation.canPop()) {
      PlayxNavigation.pop();
    }
    

Accessing Current Route Information and Managing Route Changes

• currentRoute: Gets the current RouteMatch object representing the current route in the navigation stack.

• currentRouteName: Gets the name of the current route, if available.

• addRouteChangeListener(VoidCallback listener): Adds a listener for route changes.

• removeRouteChangeListener(VoidCallback listener): Removes a previously added route change listener.

Route Bindings

Managing Route Lifecycle with PlayxBinding

PlayxBinding is an abstract class designed to help you manage actions when navigating between routes. Whether you're setting up resources when a user enters a route or cleaning up when they leave, PlayxBinding provides a clean and straightforward way to handle these tasks.

Key Points:

• Customizable onEnter/onExit: Implement onEnter for setup actions when the route is first entered, and onExit for cleanup tasks when the route is removed from the navigation stack.
• Subroute Management: The onExit method of a main route will only be called when the main route and all its subroutes are removed, making it easy to manage resources effectively.

Example:

class MyRouteBinding extends PlayxBinding {
  @override
  Future<void> onEnter(BuildContext context, GoRouterState state) async {
    // Setup logic when the route is entered.
  }

  @override
  Future<void> onExit(BuildContext context) async {
    // Cleanup logic when the route is exited.
  }
}

Configuring Routes

Advanced Routing and Custom Transitions with PlayxRoute

The PlayxRoute class extends the functionality of the GoRoute class, providing advanced features that allow developers to have granular control over routing in Flutter applications. With PlayxRoute, you can implement custom page transitions, bind route-specific lifecycle events, and configure page settings with ease.

Overview of PlayxRoute

PlayxRoute is designed to enhance navigation by offering:

• Lifecycle Management: Attach custom logic that runs when a route is entered or exited, enabling better control over the state and behavior of your app.
• Page Configuration: Customize various settings like page title, transition duration, and modal behavior.
• Custom Transitions: Apply predefined or custom animations for transitioning between pages.

1. Lifecycle Management with PlayxBinding

   • onEnter and onExit: Attach custom logic to handle what happens when a route is entered or exited. This is useful for managing resources, fetching data, or other setup/teardown tasks.
   • Redirection Handling: Implement custom redirection logic that can dynamically change the navigation flow based on your app's state.

   Example:

PlayxRoute(
      path: '/dashboard',
      name: 'dashboard',
      builder: (context, state) => DashboardPage(),
      binding: DashboardBinding(), 
    );

As discussed in the previous Route Bindings section.

2. Custom Page Configuration with PlayxPageConfiguration

The PlayxPageConfiguration class allows you to fine-tune the behavior, transitions, and appearance of routes in your application. Whether you need to customize transition durations, manage the modal behavior of a route, or configure state management, PlayxPageConfiguration has you covered.

Key Configuration Options:

• Flexible Settings: Adjust properties such as transition duration, modal behavior, and whether the route should be maintained in memory (maintainState).
• Comprehensive Configuration: Use PlayxPageConfiguration to set up the page title, key, and other important settings. This allows for detailed customization of each route.

Example:

final config = PlayxPageConfiguration.customTransition(
  transitionsBuilder: (context, animation, secondaryAnimation, child) {
    return FadeTransition(opacity: animation, child: child);
  },
  transitionDuration: Duration(milliseconds: 500),
  opaque: true,
  fullscreenDialog: true,
);

With PlayxPageConfiguration, you have the flexibility to adjust nearly every aspect of how your routes are displayed and managed, ensuring that the navigation experience matches your application's needs.

3. Creating Custom Transitions

One of the standout features of PlayxRoute is its ability to define custom page transitions or leverage existing transition types like Material, Cupertino, and fade transitions.

Predefined Transition Types:

• Material: Standard Android-style transition.
• Cupertino: iOS-style transition.
• Fade: A simple fade in/out transition.
• Native: Automatically selects the appropriate transition based on the platform.
• None: Disables any transition effects.

Creating a Custom Transition: To create a custom transition, use the PlayxPageConfiguration.customTransition constructor. This allows you to define how the route should animate when it is pushed or popped.

Example:

PlayxRoute(
  path: '/custom',
  name: 'customRoute',
  builder: (context, state) => CustomPage(),
  binding: CustomBinding(),
  pageConfiguration: PlayxPageConfiguration.customTransition(
    transitionsBuilder: (context, animation, secondaryAnimation, child) {
      return ScaleTransition(scale: animation, child: child);
    },
    transitionDuration: Duration(milliseconds: 400),
  ),
)

In this example, the route uses a ScaleTransition to animate the page with a custom scale effect. The transition duration is set to 400 milliseconds, providing a smooth and customized animation.
