avoid_web_libraries_in_flutter

Contents

Avoid using web-only libraries outside Flutter web plugin packages.

This rule is available as of Dart 2.6.

Rule sets: flutter

Details

#

AVOID using web libraries, dart:html, dart:js and dart:js_util in Flutter packages that are not web plugins. These libraries are not supported outside of a web context; functionality that depends on them will fail at runtime in Flutter mobile, and their use is generally discouraged in Flutter web.

Web library access is allowed in:

  • plugin packages that declare web as a supported context

otherwise, imports of dart:html, dart:js and dart:js_util are disallowed.
