[Flutter] - macOS Support

[Ahmadre]

Hi there :)

hope you're all doing good.

I implemented Google Sign in for Flutter with the actual plugins repo, but I am getting this:

[!] The platform of the target `Runner` (macOS 10.15.0) is not compatible with `GoogleSignIn (5.0.2)`, which does not support `macOS`.

I assume that this error is related to this repo, but some other issues here saying, that it's working for Big Sur....

any idea someone?

Edit:

[!] The platform of the target `Runner` (macOS 10.15.0) is not compatible with `GoogleSignIn (6.0.2)`, which does not support `macOS`

It looks like Flutter is still building against our previous 5.x binary release and not the recent 6.x source release you see in this repo. Neither release will build for a macOS target as we don't currently support macOS.
