Can someone tell me what does this flutter error means?-CodePudding

while I was running my Flutter app this error appear out of nowhere and I don't really understand it.

The relevant error-causing widget was: FutureBuilder FutureBuilder:file:///home/chayut/flutter-quiz-app/lib/widgets/image/image_container.dart:292:12

Does this mean my error is cause at line 292 and what does the number 12 mean?

Update: Here is the full error log. I don't know what's causing this error.
