Problem

When I run my flutter application it shows below message

Waiting for another flutter command to release the startup lock

and not proceed further.

Solution

Run the following command in Terminal.

For Mac OS

killall -9 dart

For Windows OS

taskkill /F /IM dart.exe

After Executing the Command in Terminal, Close your VS Code and Reopen the Project and let editor to complete all things. Now run your app it will run without any issue.

That’s All.

Thanks for reading.
