#437 Issue Resolved: App Crash when changing theme on SignUp Screen

New MR has been created Link !474 (merged)

Fixes #440 (closed)

Changes : In the below screenshots in the second image (previous code) the onItemSelected() function has 4 parameters and the View Parameter is expecting a not-null value but in the first screenshot we can see the fun is passing a null value which is causing the App crash. So to make the view parameter nullable type I added '?' after it in the third image (updated code). WhatsApp_Video_2023-03-23_at_5.48.41_PM
