9. Confidential + Proprietary The power of custom render • Hot reload is a magic comparing with Instant Run • Efficient tooling (Flutter inspector, doctor, tests and more) • Develop stunning MVP for entire audience in days instead of months • Support of both platforms (iOS and Android) • Say goodbye to the biggest Android developers pitfalls
10. Confidential + Proprietary Goodbye the biggest Android architecture pitfalls • IMO, crazy app lifecycle and splitted/fragmented responsibility of keeping the UI/app state is the biggest architecture pitfall in the Android framework • Flutter brings the application state back to a developer and gives a lot of power to deal with the state in a reactive manner • Also, Flutter tests is a gift comparing with instrumentation/unit testing
11. Confidential + Proprietary Goodbye UI fragmentation
12. • Open source (250+ contributors), BSD licensed • 1,100+ other packages in repository • 24,000+ Github stars • 500+ apps in Play Store • startflutter.com, flutter.rocks, flutter.institute, and more Ecosystem and community
