Hi @yashc18. Thanks for your contributions. Can you tell me how you tested that?

Hi @yashc18. Thanks for your contributions. Can you tell me how you tested that?

@amrhossamdev These changes are straightforward one-to-one replacements of equivalent attributes, so no behavioral changes are expected.

I performed the following testing after making the changes:

• Built the application to verify it compiles successfully
• Ran the app on an Android device to verify layouts render correctly
• Tested specific screens with updated layouts to ensure proper appearance
• Verified that functionality of all affected screens remained unchanged
