Add Firebase SDK

[buttonsrtoys]

Feature
Add Firebase SDK to Functions Framework so native Dart in GCP can call Firebase/Firestore.

Use Case
Flutter developers using Firestore would be much more productive if they used Dart in their backend with calls to a Firestore API. Stack would be Dart/Flutter on the front end and Dart/Firestore on the backend.

When debugging backend code, the ability to add breakpoints and step through Dart code while observing the Firestore emulator would be a game changer.

Just add Googleapis to your project dependencies to communicate to any Google API like Firestore. No need for the Dart Functions Framework to depend on it.

When will this be available?
A game changer must be introduced urgently!

@Patrick386 It makes no sense for the Functions Framework to be dependent on any Firebase specific SDK. You project should depend on something like a Firebase SKD instead.

I agree with you. I can't wait to use this function. Do you have any update on when to supported?
