package:web v1.0.0

• Added supertypes' fields to dictionary constructors as dictionaries are
  allowed to contain those fields.
• Empty dictionary constructors now create an empty object instead of being
  treated like non-object literal external constructors.
• Generate MDN API documentation for getters.
• Update the docs for generated interface types to reference the MDN Web Docs
  project.
• Address several broken links in API documentation.
• Generate APIs based on if they're on track to be a standard and not
  experimental. This is a looser restriction from the previous requirement that
  APIs need to be implemented by Chrome, Firefox, and Safari. As part of this,
  dictionaries and typedefs are only emitted if they're used by a generated API.
• Added onUnload event stream to ElementEventGetters extension methods.
• Expose ElementStream as a public class.
• Require Dart ^3.4.0.
• APIs that return a double value now return double instead of num. This is
  to avoid users accidentally downcasting num, which has different semantics
  depending on whether you compile to JS or Wasm. See issue [#57][] for more
  details.
• Fix an issue where some union types didn't account for typedef nullability.
