Compose Firebase Cloud Functions in the Dart language with firebase_js_interop

I just released firebase_js_interop which allows you to compose Firebase Cloud Functions in the Dart language. Along with my firebase_rules package it is now possible to create an entire Firebase project with only type-safe Dart code! There are a lot of components missing, but writing the interop code is tedious, not hard. With third-party contributions we should be able to get close to full interop quickly.
