This version is needed so that dart:js_interop can move to extension types. Also adds some code to handle some breaking changes: - Body -> Response. Body was an IDL interface mixin type we exposed in dart:html. Going forward, users should either use Request or Response. - Casts to JSAny. These are temporary until we move package:web types to extension types. Currently, package:web types can't implement JSObject as JSObject will move to be an extension type itself.

Image List
An example that sets up a local HTTP server for serving one image then creates a single flutter widget with five copies of requested image and prints how long the loading took.
This is used in [$FH/flutter/devicelab/bin/tasks/image_list_reported_duration.dart] test.
