“To the metal” approaches “Cross platform” approaches Must fund two apps Two teams, codebases, & investments Inconsistent brand, features Different across devices & OEMs Poor Performance Slow, jerky, unpredictable Non-Native Look/Feel Users can tell the difference High-quality apps Platform and system integrations Fast development Quick iterations, hot reload High-performance UIs Native code, GPU accelerated Portability, reach Single codebase Challenges of mobile development today

Quick DEMO 

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 

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 

Confidential + Proprietary Goodbye UI fragmentation 

● 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
