PR Summary

• Introduction of a 'WithTheme' Method A new method has been added into two of the project files, ViewInterface and ViewTrait. This function, named withTheme, allows a specific theme to be applied within the application by passing this theme into the function. The output of this function is a new version of the view with the chosen theme applied.

• Testing of the 'WithTheme' Method For ensuring reliability and correctness, a test case has been established for the 'withTheme' method. This specific test, which resides within the ViewTest.php file, verifies that when a theme is applied through the 'withTheme' method, it accurately generates a fresh instance of the view with the chosen theme. Furthermore, it double-checks to ensure that the initial view remains unmodified.
