Can't Install Flutter on Windows

I’m trying to install Flutter using VS code and it shows this error:

error installing flutter

What happened:
Firstly, I had Flutter installed and worked fine. All projects build fine, and everything is going well. I tried to install Firebase then Fluuterfire it made some errors, then I cancelled it. I returned to my projects on VS code it had errors building. I tried to uninstall Flutter and reinstall it, I uninstalled but couldn’t reinstall due to these errors.

I tried to uninstall Flutter extension, Dart Extension, VS code, Git, and delete Flutter SDK files and that doesn’t work.

I think some file of Types may be missing, here is a list of environment variables if it can help:

    I found the problem was in the packages installed by pub.dev.

    1- I deleted the cache folder which is located in C:Users<user name>AppDataLocalPub

    2- Deleted flutter SDK folder

    3- restarted my PC

    4- run PowerShell <your project path> flutter clean

    5- run flutter run

    6- worked!

    Note: before I do this, even flutter command or flutter doctor was taking time and not responding.
