First you'll play with the Dart language in your browser, no download required. Then you'll install the Dart SDK, write a small program, and run that program using the Dart VM. Finally, you'll use an AOT (<em>ahead of time</em>) compiler to compile your finished program to native machine code, which you'll execute using the Dart runtime.</p><div class="header-wrapper"><h2 id="1-play-with-dart-code-in-dartpad">1.
