You can now use existing JavaScript code with Dart! We've recently released a JavaScript-Dart interop library , one of our developers' most requested features. This is a big milestone for the Dart project.Using this library, you can proxy JavaScript objects inside Dart code. You can also reach Dart functions from JavaScript code.Here's an example of wrapping a Google Maps API object:This code instantiates a JavaScript google.maps.Map object onto the given canvas and returns a proxy to Dart. Note that googlemaps.Map is a proxy to the JavaScript constructor. The resulting googlemap is a proxy to the actual Google Map object in JavaScript.Here's an example of calling a Dart function from JavaScript:You can read more about using existing JavaScript code inside your Dart apps . As always, please join the discussion at the Dart mailing list or on Stack Overflow . Thanks for trying Dart!
