Speed up Dart/Flutter with Futures, Streams and StreamTransformers

Not a single person in this world enjoys waiting. Waiting for apps to be ready is a terrible user experience. Unfortunately, users won’t hesitate to leave a one-star rating when content takes too long to load.

One of the projects I have been working on requires many assets to be downloaded from the server and saved locally on the device. This means lots of waiting. Especially for new users that require all of these assets to be downloaded at once.
