You can use lazy initialization with late.

BuildContext? myContext;
 
late final foldertitle =....;

Also you can use initState. but you may need to create variable for BuildContext, better will be passing using method.

It was added on null-safety,you can check analysis_options default rules, and [lazy-initialization ](https://dart.dev/null-safety/understanding-null-safety#lazy-initialization) – Md. Yeasin Sheikh Mar 29 '23 at 18:28
