Building a cross-platform DroidCon app using Flutter
summary
Built a working DroidCon Berlin 2019 app for Android, iOS and web in about 72 hours for Android iOS web using Flutter; data is moved from provided Droidcon REST APIs into Firestore and favorites use Firebase for favorites + analytics (remote config flips features). Authentication uses Twitter (guest was later considered), crash reporting uses Sentry for crash reporting after Firebase conflicts, web required firestore-dart and tweaks, UI parity mostly succeeds but a few platform bugs and high web reads occur.
