Flutter is not loading devices and says 'Waiting for another flutter command to release the startup lock...'

Question

My Flutter project is not loading devices and says 'Waiting for another flutter command to release the startup lock. Here is what I've done so far but it didn't work:

I've removed this file:

/bin/cache/lockfile

I've opened the terminal and wrote:

killall -9 dart

Please let me know what else I could try to get this working?

If you are using Android Studio, go to Preferences and inside framework go in Flutter, then set the SDK path. It may be not there.

It often happens when we upgrade or downgrade SDK, it removes the path. Also try Flutter clean and Flutter doctor before setting the Flutter SDK path.
