Waiting for another flutter command to release the startup lock

When I run my flutter application it show

Waiting for another flutter command to release the startup lock

this messages and not proceed further.

Solution

  • In my case, the following command in Terminal helped (as suggested by Günter Zöchbauer's comment):

    killall -9 dart

    On Windows, run the following in a Command Prompt or PowerShell window (as suggested by upupming's comment):

    taskkill /F /IM dart.exe

    (You can read about taskkill flags in Windows here)
