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

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.

Enable

#

To enable the avoid_web_libraries_in_flutter rule, add avoid_web_libraries_in_flutter under linter > rules in your analysis_options.yaml file:

analysis_options.yaml
yaml 
linter:
  rules:
    - avoid_web_libraries_in_flutter

If you're instead using the YAML map syntax to configure linter rules, add avoid_web_libraries_in_flutter: true under linter > rules:

analysis_options.yaml
yaml 
linter:
  rules:
    avoid_web_libraries_in_flutter: true

Unless stated otherwise, the documentation on this site reflects Dart 3.9.2. Report an issue.
