Pattern: Use of web library outside Flutter web plugin package

Issue: -

Description

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 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.
