Answer 2

Nothing of ALL these answers didn't helped me.

The only one solution was to remove whole flutter stuff (and reinstall flutter from git):

<flutter directory>
<user>/.flutter_tool_state
<user>/.dart
<user>/.pub-cache
<user>/.dartServer
<user>/.flutter

In Android Studio, It's Work for me

Stop your app if it still runs on the phone or disconnect the your testing device.

Then try to install the package again.

Answer 4

1. Turn off Android Studio.

2. Open flutter installation directory /bin/cache.

3. Delete lockfile.

4. At this point, you can execute the flutter related command on the command line to solve the problem perfectly.
