How to access particular variable in another function call in flutter? - flutter

Question

In the below code I want to access 'selectFront' and 'selectBack' variables from onTap() method of InkWell(). If I globally declare variable with late initialization it throws an error. What is the another good way to access those variables in another OnPressed() method of TextButton?
