Introducing Flutter Custom Carousel

We’re really excited to introduce a new package called Flutter Custom Carousel, a widget for creating fully custom, animated scrollable lists. It manages all of the tricky logic surrounding scroll interactions and physics, and leaves the visual presentation of items up to you.

The interesting thing here, is that the controller portion, is a fairly stable, boring API. Reading or writing the url location, or accessing queryParams is all pretty straight-forward. Really all you are doing here is setting a string value, and parsing query params using the URI class.
