Unable to run flutter -v or flutter doctor in command prompt on Windows 10

Question

I come to this issue whenever I try to run Flutter command on command prompt on Windows 10 Pro.

PS C:\src\flutter> flutter doctor
Building flutter tool...
Running pub upgrade...

Error: Unable to create dart snapshot for flutter tool.

Looking like it gets stuck at

running pub upgrade

How can this be fixed?

Answer 1

Navigate to the flutter install directory and run the following commands

git clean -xfd
git stash save --keep-index
git stash drop
git pull
flutter doctor

And your problem should be fixed.

Note:

For those on windows, if you use git bash you'll have a problem like: Downloading Dart SDK from Flutter engine fee001c93f25a1e7258e762781a7361f122d29f5... Unknown operating system. Cannot install Dart SDK.

Use windows terminal directly.
