Introduction to Dart Language

Dart is a client-optimized language for fast apps on any platform.

1. Optimized for UI

Develop with a programming language specialized around the needs of user interface creation

• Mature and complete async-await for user interfaces containing event-driven code, paired with isolate-based concurrency

• A programming language optimized for building user interfaces with features such as the spread operator for expanding collections, and collection if for customizing UI for each platform

• A programming language that is easy to learn, with a familiar syntax

2. Productive development

Make changes iteratively: use hot reload to see the result instantly in your running app.

• Make changes to your source code iteratively, using hot reload to instantly see the effect in the running app

• Write code using a flexible type system with rich static analysis and powerful, configurable tooling

• Do profiling, logging, and debugging with your code editor of choice

3. Fast on all platforms

Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

• AOT-compile apps to native machine code for instant startup

• Target the web with complete, mature, fast compilers for JavaScript

• Run backend code supporting your app, written using a single programming language
