Proposal

web plugin is using dart:html which is not compatible with WASM, migrate to package:web.

Context: The unavailable library 'dart:html' is imported through these packages: web_plugin_registrant.dart => package:permission_handler_html => dart:html

Pitch

Flutter doc: https://docs.flutter.dev/platform-integration/web/wasm

Target dart2wasm failed: ProcessException: Process exited abnormally with exit code 64:
