The Dart web platform supports calling JavaScript using the js package, also known as package:js.

For help using the js package, see the following:

• Documentation for the js package:
  • Pub site page
  • API reference
• Packages that use the js package:
  • firebase_web is a good example of providing a Dart-like API to a JavaScript library.
  • sass is an example of a more unusual use case: providing a way for JavaScript code to call Dart code.
