Answer 1

Try any one of the following steps:

1. Goto Files > Click Invalidate Caches/Restart

2. Restart your machine

3. On terminal write flutter clean and then flutter run

Answer 2

I had the same issue after setting up my flutter project to run on iOS. When I tried to run it back on Android, this error was thrown.

This worked for me (on Windows):

1. Close your project and close your code editor

2. Open Task Manager

3. Finish all vscode-related tasks you see (or related to the IDE you are using)

4. Finish all Java-related tasks, inclidung OpenJDK Platform binary (there are usually two of these; finish both)

5. Go to your project's root folder and delete the build folder

6. Open your project again and run

Good luck!
