PreloadRequest class

A single Preload.load in flight.

It carries progress, it notifies its listeners as assets land, and it completes as a Future. Dispose it once you are done with it:

final request = Ignis.preload.load(manifest: true);
// ...drive a progress bar from `request`...
await request;
request.dispose();
