Devfest App 2019 was developed using Flutter and Dart. This application was the first ever GDG Devfest App in the Philippines to be published in both the Google Play and Apple App Stores.
This app served as the catalouge and booking app of the event. Using Firebase Cloud Firestore for Flutter enabled us to support both online and offline experiences seamlessly for the catalouge app. Lastly, with the proper setup and cost-effectiveness in mind, we peaked at 478K reads, 2K writes, with a total operation count of 553549 while only paying $0.27 after the event.
