Answer 4

1. Delete pubspec.lock file
2. Run "flutter pub get" from terminal or editor shortcut ("get packages" AndroidStudio or this logo Visual Studio) in pubspec.yaml file.
3. Wait for download.
4. If it doesn't work relaunch your editor then repeat step 2..

Answer 5

This also happens when you have opened the flutter project in the Editor. Close the Editor and re-run the command

Answer 6

You can remove flutter and "install 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 we would like to go to directory so "one 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 receive some info about it or correct 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 commands should work (and Flutter will fetch some necessary data).
