Answers 2 : of Waiting for another flutter command to release the startup lock

Remove this file:

<YOUR FLUTTER FOLDER>/bin/cache/lockfile

This releases the occupied lock and anycodings_command makes you able to run other commands.

Answers 3 : of Waiting for another flutter command to release the startup lock

1. Stop all running dart instances

If you're using Android Studio save your anycodings_command work and close it. And open your anycodings_command terminal to kill running dart instances.

Those commands will kill all dart anycodings_command instances including the ones created by anycodings_command editors for code analysis and debug anycodings_command instances. So be careful before anycodings_command executing

Linux:

killall -9 dart

Windows:

taskkill /F /IM dart.exe

2. Remove lockfile

You can find lockfile inside flutter anycodings_command installation directory.

<flutter folder>/bin/cache/lockfile

Answers 5 : of Waiting for another flutter command to release the startup lock

You can try to kill all flutter anycodings_command processes.

TL;DR - go to point 4)

1) List of the processes:

ps aux

2) Search name containing with flutter:

ps aux | grep flutter

where output can be like there:

stackoverflow 16697 1.5 0.0 4288316 704 ?? S 10:02PM 0:15.80 bash /flutter_path/flutter/bin/flutter --no-color build apk stackoverflow 2800 1.5 0.0 4288316 704 ?? S 9:59PM 0:18.49 bash /flutter_path/flutter/bin/flutter --no-color pub get stackoverflow 1215 1.5 0.0 4280124 700 ?? S 9:58PM 0:18.89 bash /flutter_path/flutter/bin/flutter --no-color config --machine stackoverflow 8449 1.5 0.0 4296508 716 ?? S 10:00PM 0:17.20 bash /flutter_path/flutter/bin/flutter --no-color pub get stackoverflow 1326 1.4 0.0 4288316 708 ?? S 9:58PM 0:18.97 bash /flutter_path/flutter/bin/flutter daemon stackoverflow 16687 0.0 0.0 4279100 820 ?? S 10:02PM 0:00.01 bash /flutter_path/flutter/bin/flutter --no-color build apk stackoverflow 8431 0.0 0.0 4288316 804 ?? S 10:00PM 0:00.02 bash /flutter_path/flutter/bin/flutter --no-color pub get stackoverflow 2784 0.0 0.0 4288316 704 ?? S 9:59PM 0:00.01 bash /flutter_path/flutter/bin/flutter --no-color pub get stackoverflow 1305 0.0 0.0 4280124 712 ?? S 9:58PM 0:00.01 bash /flutter_path/flutter/bin/flutter daemon stackoverflow 1205 0.0 0.0 4279100 788 ?? S 9:58PM 0:00.01 bash /flutter_path/flutter/bin/flutter --no-color config --machine stackoverflow 11416 0.0 0.0 4268176 536 s000 R+ 10:18PM 0:00.00 grep --color flutter

3) Get processes ID

We need content from second column (from anycodings_command above output):

ps aux | grep flutter | awk '{print $2}'

4 a) Kill "automatically":

To list, search and kill all of them you anycodings_command can use

kill $(ps aux | grep flutter | grep -v grep | awk '{print $2}')

(you can run it also with sudo)

or

ps aux | grep flutter | grep -v grep | awk '{print $2}' | xargs kill -15

4 b) Kill manually

You can kill processes one-by-one using:

sudo kill -15 <process_ID>

e.g. to kill process with id 13245 use:

sudo kill -15 13245

If -15 will not work, you can try -2 or anycodings_command -1.

Final option it is -9 which should not anycodings_command be used because it prevents the process anycodings_command from doing any cleanup work.

For me, the issue's root cause on my Mac anycodings_command device was a version of the flock binary anycodings_command it was not expecting. Removing it from anycodings_command the path did the trick; probably a BSD anycodings_command vs GNU syntax issue.

For Newbies

The simplest solution, although a little anycodings_command time consuming would be to restart your anycodings_command computer or simple logout from the anycodings_command current user and login again.

Answers 20 : of Waiting for another flutter command to release the startup lock

You can remove flutter and "install anycodings_command again", so fastest way is to:

1) Check where you have flutter (as executable)

To check it, you can run:

which flutter

And you can expect such output:

/your_user/your_path/flutter/bin/flutter

2) Go to this directory

Above path is directly to flutter, but anycodings_command we would like to go to directory so "one anycodings_command earlier" in path:

cd /your_user/your_path/flutter/bin

3) Check is it git repository

It should be, but it's worth to check.

Run one of the git command e.g.

git status

or

git branch

When it's git repository you will anycodings_command receive some info about it or correct anycodings_command list of branches.

4) Remove all of the files

rm -R *

5) "revert" removal to have only necessary files:

git co -- .

6) Voila!

You can run just flutter version and anycodings_command commands should work (and Flutter will anycodings_command fetch some necessary data).
