When I run my flutter application it show
Waiting for another flutter command to release the startup lock
this messages and not proceed further.
回答1:
In my case, following command in Terminal helped (as suggested by Günter):
killall -9 dart
On Windows (as suggested by upupming):
taskkill /F /IM dart.exe
回答2:
Remove this file:
<YOUR FLUTTER FOLDER>/bin/cache/lockfile
This releases the occupied lock and makes you able to run other commands.
回答3:
In Windows :
Press: Ctrl + Alt + Delete
- In task manager find out your editor such as VS Studio or Android Studio
- In that Find "dart" and End that Task
- Then close your editor
- Open editor again
- let editor to complete all things, after that run your query that will work

I use a Mac with Visual Studio Code and this is what worked:
Shutdown your PC and switch it on again. Don't use the restart function. I restarted 2 times and it didn't work. Only shutdown worked.
PS: I tried out the following:
- Delete lockfile;
- Run
killall -9 dart; - Restart my PC.
But they all didn't work.
回答5:
Exit from your IDE, then from start manager stop all dart related files(if any have).
Then go to"FLUTTER DIRECTORY"/bin/cache/lockfile
and delete this lockfile
回答6:
I tried all previous suggestions but without benefit. Finally when I connect my pc to internet and wait flutter to release then 5 minutes solved
回答7:
This also happens when you have opened the flutter project in the Editor. Close the Editor and re-run the command
回答8:
For Ubuntu Linux
killall -9 dart
This worked for me even when IDE was on
回答9:
If you are using Windows, you can open the task manager and under the 'Processes' tab search for processes named 'dart'. End all those tasks.
