Best way to override single method in Illuminate\Foundation\Application through service provider - laravel

Question

I just made changes to the application structure for my Laravel application. It works well when runnning tests (for the Http controllers). The problem is when i try to run artisan commands (that literally need to access "getNamespace()" method), it wont resolve the namespaces.
Here are the composer.json:
"autoload": {
"psr-4": {
"App\\": "app/",
"Database\\Factories\\": "database/factories/",
"Database\\Seeders\\": "database/seeders/",
"Modules\\": "modules/"
},
"files": [
"app/Helpers/app.php",
"app/Helpers/form.php",
"app/Helpers/view.php"
]
},
"autoload-dev": {
"psr-4": {
"Tests\\": "tests/"
}
},
I do aware that i can add Modules\ModuleA, Modules\ModuleB to the composer json, but that put alot of work. So i decided to override the getNamespace() method instead, but what is the best way to override single method illuminate/foundation/xxx classes through service provider?

If you want to override a single method in Illuminate\Foundation\Application through a service provider in Laravel, you can use the following steps:
Create a new service provider by running the command php artisan make:provider YourServiceProvider in your terminal.
In your YourServiceProvider class, extend the Illuminate\Support\ServiceProvider class.
Override the register() method in your YourServiceProvider class. In this method, you can bind your custom implementation of the method you want to override to the container. For example, if you want to override the loadEnvironmentFrom() method, you can do so as follows:
use Illuminate\Foundation\Application;
class YourServiceProvider extends ServiceProvider
{
public function register(){
$this->app->bind(Application::class, function ($app) {
return new class($app) extends Application {
public function loadEnvironmentFrom($file)
{
// Your custom implementation here
}
};
});
}
}
Then in your config.app file, add the service provider to the list of providers:
'providers' => [
// Other service providers
App\Providers\YourServiceProvider::class,
],
This way, the method you've overridden will use your custom implementation instead of the default implementation in Illuminate\Foundation\Application.
Hope this helps
