update deprecated code

[maxiicodes]

I fixed the following deprecations which were reported by the dart analyzer:

• removed the androidOverscrollIndicator property since this is the default behavior in material 3 now
• renamed bodyText1 to bodyLarge

Hi. Theme.of(context).textTheme.bodyLarge!.color has to be replaced with Theme.of(context).colorScheme.onSurfaceVariant. Since the Material 3 implementation I decided to pick the colors from the colorScheme object, which is generated by Flutter based on a given color, or based on the dynamic theme of the system.

Ok, I've done that too. Is there anything else I can update? ^^

Merged! Thanks for your work. Greetings from Spain.
