Steps to Reproduce

This process has happened 3 times this morning. Does not matter whether or not IntelliJ is open.

• in app root folder, open a terminal window
• "git pull origin master"
• when it's finished, run a clean script
• in new terminal window, "flutter packages get" (sticks if not in new window)
• wait 10 minutes, nothing seems to be happening
• kill terminal
• open new terminal, "flutter packages get"

... get message "Waiting for another flutter command to release the startup lock..."

have to reboot to try again.

Logs

Can not "flutter run", get message "Waiting for another flutter command to release the startup lock..."

Flutter Doctor

What platform?
If you reboot, can you run flutter doctor -v? What does it say?
What does ps aux say?

In older Flutter versions this was common when build_runner was used #17422

update
#14703 is similar and still open. I thought this was fixed already.

Hello guys,
I was also facing this issue in Android studio .And solved it by uninstalling both flutter and dart plugins. When we reinstall them issue is gone .
Good luck .

Open your task manager then check for adb.exe processes running and end them.... That worked for me
