`ExternalDartReference` will no longer implement `Object` as it will now have a nullable representation type.
`ExternalDartReference` allows users to pass opaque references to Dart values through JavaScript. In order to avoid extra null-checks and downcasts, this type will now represent a generic Dart value that is a subtype of `Object?`, and therefore can't implement `Object`.
See https://github.com/dart-lang/sdk/issues/56015 for more details. If this breaking change poses a severe problem, please leave a comment on the issue.
