Identify Route's Group in Middleware - laravel

Question

My ultimate objective is to limit accesses to the group of routes by validating permissions provided to the user.
These target 'group of routes' have ONE COMMON PARENT GROUP and may have zero or more sub-groups, such that, if access to these target 'group of routes' is permitted/accessible to the user then, all its sub-route groups are also accessible to the user.
To achieve this, I believe I need to differentiate these target group of routes by any uniqueString/parameter in middleware, which is indeed answered here.
But, I want to generalize this further, by applying middleware to common SINGLE PARENT GROUP of all these target group of routes and identify these target group of routes by any means in the middleware.
So, my question is how do I identify/differentiate these target group of routes in the middleware? Is there any way to do so?
Sample Code of what I am trying to describe:
Route::group(['prefix' => 'singleParent','middleware' => 'permissionMiddleware'], function (){
Route::group(['prefix' => 'target-group-1', 'groupUniqueString' => 'tsg1'], function (){
Route::group(['prefix' => 'sub-group-1.1'], function (){
});
Route::group(['prefix' => 'sub-group-1.2'], function (){
});
});
Route::group(['prefix' => 'target-group-2', 'groupUniqueString' => 'tsg2'], function (){
Route::get('route-1','Controller#method-of-Route1');
});
});

So, to specify a route group in your middleware to handle some actions, you can do it in this way :
Route::group(['prefix' => 'singleParent','middleware' => 'permissionMiddleware'], function (){
Route::group(['prefix' => 'target-group-1', 'as' => 'tsg1.'], function (){
//...
});
});
This will generate route names with the prefix : tsg1
Now in your middleware you can do like this to get the route group :
function getCurrentRouteGroup() {
$routeName = Illuminate\Support\Facades\Route::current()->getName();
return explode('.',$routeName)[0];
}
Updated
and to check :
if ($request->route()->named('name')) {
//
}
return $next($request);
Or in another approach you can achieve :
To get the prefix of a route group you can do something like this :
$uri = $request->path();
// this will give you the url path like -> if this is the url :
// http://localhost:8000/foo/bar you will get foo/bar
And then :
$prefix = explode('/',$uri)[0];
// and you will get 'foo'
Let me know if this works for you.
