“Flutter is a new mobile app SDK to help developers and designers build modern mobile apps for iOS and Android.” Modern, reactive framework allows us to build powerful UI with animations, shared codebase and views over iOS and Android platforms. It makes development process easier, development costs at minimal and rapid deployment. Flutter is build with C, C++, Dart and Skia. And the most beautiful part is that all release code is compiled in native code (Android NDK, LLVM, AOT-compiled) without interpreter involved. If you are familiar with performance drawbacks of hybrid frameworks you can easy say that flutter compile fastest code very close to pure native performance.
