Please add cloud firestore

Hi @venky9885 .
I'd love to add support for cloud firestore. However, I work on this project in my spare time and I don't have that much. If you really need it, please consider sponsorship. It would allow me to concentrate more on this project.

A temporary workaround is to use firedart for firestore, and firebase_dart for auth

And initialize Firestore using firebase_auth

Firestore firestore = Firestore(
        firebaseOptions.projectId,
        authenticator: (Map<String, String> metadata, String uri) async {
          String? idToken = await _auth.currentUser?.getIdToken();
          metadata['authorization'] = 'Bearer $idToken';
        },
      );
