Unable to build flutter app. git clone failed

Describe the bug
Unable to debug a flutter app with a Mac for days. Every run ends with this error

**Installing AppAuth (1.5.0)

[!] Error installing AppAuth
[!] /usr/local/git/bin/git clone https://github.com/openid/AppAuth-iOS.git /var/folders/sp/bt0ltdxd4mnf5tp3l_608l880000gn/T/d20220407-18938-1unjube --template= --single-branch --depth 1 --branch 1.5.0

Cloning into '/var/folders/sp/bt0ltdxd4mnf5tp3l_608l880000gn/T/d20220407-18938-1unjube'...
fatal: protocol '”git' is not supported
**
I currently have git installed on the Mac and it works fine

To Reproduce
Steps to reproduce the behavior:

1. Add firebase_auth and google sign in to your flutter project
2. Resolve flutter dependecies
3. Run "pod install" or try to run debug with ios emulator
4. See error

Expected behavior

Everything resolves except AppAuth

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Mac OS Big Sur
• Version: 12.3,1

Start with the reported pod install or iOS debug flow and inspect the AppAuth 1.5.0 git clone command, especially the malformed protocol shown in the error. Reproduce with firebase_auth and Google Sign-In on macOS Big Sur; done means AppAuth resolves successfully and the Flutter iOS app builds.
