[FR] Type hint the source code

[takos22]

Is your feature request related to a problem? Please describe.
When developing with this library, I constantly have to type hint variables returned by the functions, so my autocompleter suggests the right properties and for cleaner code.

Describe the solution you'd like
It would be great if you could type hint the library or at least the public API in order to help type checkers, autocompleters and collaboration.

Describe alternatives you've considered
None

Additional context
None

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @takos22, Thank you for the feature request!
We agree that this will be a great addition to improve the SDK. While I cannot promise you a timeline at the moment, we will use this github issue to track the progress in the future.

In the meantime, you can also help us speed things up by providing PRs! :)

Do you have any progress on it? I still get infrastructure\push_notifications.py:7: error: Skipping analyzing "firebase_admi n": module is installed, but missing library stubs or py.typed marker error on mypy :(

@lahirumaramba, maybe you can add py.typed file to the library? This will remove the message from mypy. And then add types.
