Background coolor change

Hi there! I wanted to ask if anyone knew how to have a settings screen where there is an option for the user to change the background color of the entire app and to modify the volume of the sound effects.

PLEASE HELP ASAP

Hello @22-036to1y Welcome to the community.
You can use TinyDB to save values of the settings that user will make and then apply those to other screens very easily by getting those values from the TinyDB on each screen.
