Flutter and Firebase are a great match for rapid prototyping and full on production ready redeployment for native mobile applications. This talk included a demo of a Flutter application that reads content from a Contenta CMS API (Drupal distribution) and reads/saves related data to a Firebase Firestore. The application is a companion application for a pseudo Recipe Magazine (Unami - https://www.drupal.org/project/ideas/issues/2847582).
