What is Dart in Flutter..??
Dart is the programming language which Flutter adopted to build a cross-platform application. Google has developed this language and optimized in UI, and it is suitable for the fast development of visually rich applications on Flutter.

Characteristics of Dart
a) Object Oriented: It is completely an object-oriented language having a class, interface, and strong type, just like Java, Kotlin, Swift. b) Compiled Language: The Dart can be compiled to native code beforehand for quick start up and runtime on mobile and desktop and just in time (JIT) at runtime for quick reload in development. c) Optimized for UI: It has been designed such that the Dart deals with complex animations and smooth transitions in user interfaces so as to cater to the level of performance required by Flutter. d) Asynchronous Programming: Dart natively allows support for asynchronous programming via its use of the async and await keywords, so using the application to handle requests like making network requests or accessing the file system is significantly simpler.
Why Dart is Used in Flutter
a ) High Performance: Because Dart compiles the application into native code, a technique known as ahead of time compilation (AOT), Flutter applications are rendered to run at near native speeds on both iOS and Android. b) Hot Reload: This feature of JIT compilation makes it possible for developers to take advantage of Flutter hot reload. This means lots of saving of time, as the changes may now be implemented directly within code immediately. c) One Language: This language allows the person working with both front-end user interface designing and the back-end logics in one language so makes the entire process so smooth. d) Consistent UI Rendering: The structure and features of the Dart language allow Flutter to directly draw each pixel on the screen, therefore allowing a look and feel that is platform-independent.
Syntax and Features of Dart
Clean and modern syntax balances flexibility and robustness with a mixin of static and dynamic typing.Some key syntax and features are: a) Null Safety: Dart has null safety, which prevents runtime null reference errors. b) Rich Collection Types: It has lists, maps, sets, and much more. c) Sound Typing: It provides a type system that will catch errors at compile time.
