Flutter throws an error on application run

Question

I was trying to run my flutter app that worked just fine. But, after an update, it throws the following error.

I've updated the Build.gradle file(app level), added a compile sdk version(31). I've also updated the dependencies there are. But, none seem to help.

Answer 1

After some long surfings, here's what worked for me that enabled me to successfully run the code again.

Run the following commands and that might solve the issue.

flutter pub outdated
flutter pub upgrade

flutter channel master
flutter upgrade

it's likely that it was coming from one of my dependencies, and that it hasn't since been updated to account for the changes to File.
