Flutter is based on Dart – a programming language that helps you build high-quality, fast, and easy-to-maintain apps. Dart is an open-source language and the Flutter toolchain is the only one designed to create production-quality apps for iOS and Android.
Due to its reactive nature, you can code Flutter apps at a much faster rate than native app development. Additionally, with platform integrations allowing code reuse, your overall app development time can be reduced significantly.
You can expect a smooth cross-platform experience with Flutter as it provides compatibility with both iOS and Android platforms.
