GetX Navigation

Priority: P0 (CRITICAL)

Decoupled navigation system allowing UI transitions without BuildContext.

Implementation Guidelines

• Prefer Named Routes: Use Get.toNamed('/path') for better maintainability. Define routes in a centralized AppPages class.
• No Context Navigation: Leverage Get.to(), Get.back(), etc., directly from controllers.
• Navigation Methods:

- Get.to(): Navigate to next screen. - Get.off(): Navigate and replace current screen (e.g., Splash -> Home). - Get.offAll(): Clear stack and navigate (e.g., Logout -> Login). - Get.back(): Close current screen, dialog, or bottom sheet.

• Bindings Everywhere: Always link routes with Bindings to manage controller lifecycles.
• Middleware: Use GetMiddleware for route guards (Auth, Permissions) instead of logic inside views.

Code Example

// Route Definition
static final routes = [
  GetPage(
    name: _Paths.HOME,
    page: () => HomeView(),
    binding: HomeBinding(),
    middlewares: [AuthMiddleware()],
  ),
];

// Usage in Controller
void logout() {
  _authService.clear();
  Get.offAllNamed(Routes.LOGIN);
}

// Route Guard
class AuthMiddleware extends GetMiddleware {
  @override
  RouteSettings? redirect(String? route) {
    return isAuthenticated ? null : RouteSettings(name: Routes.LOGIN);
  }
}

Anti-Patterns

• Mixing Context and GetX: Do not use Navigator.of(context) when GetX is the primary router.
• Hardcoded Strings: Always use a Routes constant class for names.
• Dialogs without GetX: Use Get.dialog() and Get.snackbar() for consistency.
