How to define a route with a namespace in Laravel?

In Laravel, you can define a route with a namespace by using the namespace method within the Route facade. Here's how you can do it:

Open your routes/web.php or routes/api.php file.
Use the Route facade to define a route with a namespace. The namespace method allows you to specify the namespace for the controller that will handle the route. Here's an example:

use App\Http\Controllers\Admin\AdminController;

Route::namespace('Admin')->group(function () {
    Route::get('/admin', [AdminController::class, 'index']);
});

In this example, we have defined a route with the namespace Admin. The AdminController will handle the /admin route.

You can also add a prefix to your route URL if needed. Here's an example:

use App\Http\Controllers\Admin\AdminController;

Route::namespace('Admin')->prefix('admin')->group(function () {
    Route::get('/', [AdminController::class, 'index']);
    Route::get('/dashboard', [AdminController::class, 'dashboard']);
});

In this example, we have added a prefix /admin to both routes. So, the routes will be /admin and /admin/dashboard, and both will be handled by the AdminController.

That's it! You have defined a route with a namespace in Laravel.
