What programming language is used to write Flutter apps?

Answer

Flutter uses Dart, a client-optimized programming language developed by Google. Dart supports both JIT (Just-in-Time) compilation during development — enabling Hot Reload — and AOT (Ahead-of-Time) compilation for fast, high-performance production builds. Its syntax is clean and familiar to developers coming from Java, Kotlin, or JavaScript backgrounds, making it easy to pick up quickly.
