I have been looking for a solution for about two weeks now, and I still have not found the problem. Thank you for any help!

THE ANSWER IS POSTED IN THE COMMENTS

Solution 1

I resolved the whole problem, by deleting the folder "build" in the project file.

Solution 2

Run flutter clean and flutter pub get commands in your project folder

Looks like your problem could be there: java.nio.file.AccessDeniedException: C:\Users\risha\development\flutter\willtenn\build\app\genera‌​ted\source\buildConf‌​ig\debug\com\example‌​\willtenn , looks like flutter have no permission to write in this directory
