Flutter is an open source UI mobile app Software Development Kit for creating rich and fluid native interfaces for both iOS and Android powered by Google. It offers best Cross-Platform App Development by keeping single codebase. Features like hot reload, widget, libraries help to build beautiful native apps in record time.

Moreover, all the release code is compiled using native code such as Android NDK, LLVM, and AOT- compiled that do not require interpreter involvement, resulting in the delivery of the fastest code that is extremely close to the pure native performance.
