[Bug]: Incorrect Theme Toggle Implementation in ThemeCubit (theme_cubit.dart)

[PadmnabhTewari]

The toggle method in ThemeCubit is used to switch between light and dark themes. However, an issue in the logic or implementation may result in the theme not toggling as expected. This task requires reviewing and fixing the theme toggle functionality to ensure it correctly switches between light and dark modes.

Expected behavior

If this method is incorrectly implemented, users may experience unexpected behavior when toggling themes. For example, the theme might not persist between app restarts or may not toggle correctly when the user interacts with the theme switch.

Review the toggle method and ensure it correctly switches the theme state.
