Analysis and Solution for 'Class \'\\App\\User\' not found' Error in Laravel When Changing Namespace
This paper provides an in-depth examination of the 'Class \'\\App\\User\' not found' error that occurs when migrating the User model from the default App namespace to the App\Models namespace in the Laravel framework.
