Zero to App: Live Coding a Cross-Platform App on Firebase (Google I/O'19)

Firebase makes it easy to build a cross-platform app. How easy? Let's try it out together! In this session our team live-codes an app on stage for Android, iOS, and Web. Each platform will have the same functionality, built upon the same Firebase features. They will start with Firestore, Authentication, and Storage, and then show how to use Cloud Functions to integrate Google Cloud Platform's advanced APIs into the application.

While this is pretty cool demo, having four screens at a time means that here on YT, we can't really read any of them well, even at full screen.

[@spicymustard9066]

Great video. Love Firebase and the team behind it! That semi panicked whispering though haha, classic live coding. Thank you all!

[@Frank_van_Puffelen]

We had some network issues on the Android emulator early in the demo. :)

quick question, how did you read/ transfer the receipt, an image to total expense, an double? by cloud function ? backend machine learning ? what is the code is used. thanks

[@patheticgeek]

its vision api, google it, it is in the firebase they showed the code rewatch the start when they start writing function

I didn't find the github repo, but for the receipt method on firebase function I've found this article that explain how to get the total : medium.com/@teresa.wu/googles-ml-kit-text-recognition-with-sample-app-of-receipts-reading-7fe6dc68ada3

[@MudassirZulfiqar]

Why not on flutter?

[@LifeCasts]

Bro its the clound functions which does the magic, you get the file

[@amansahu6799]

Why wasn't it created using Flutter SDK? Shouldn't Google be promoting it?

[@manukumarojha7764]

wow 1st comment

[@gofudgeyourselves9024]

They should have done this with Flutter

[@SacWebDeveloper]

Missed an opportunity to show all three frontends written in a single codebase with Flutter.

[@caballero75RS]

This is how you write an app for IOS, Android and Web when you don't know Flutter.

[@jefffrazier6813]

Wow. What a failed opportunity to promote Flutter here.
