Loadable slider

[tinolaomahei]

Description

When performing an action using this widget, I think it would be useful to convey a loading state before the slider is complete or reset. This PR attempts to allow consuming apps to perform some work i.e. call an API, set the slider into a loading state and then once the work is complete, have the slider continue its complete animation.

• Loading animation

Please treat this PR as a prompt to a discussion rather than a mergeable PR as I'd imagine we'd want the loading icon to act like a spinner or perhaps allow the animation to be defined in an attribute on the slider?

Look forward to a review when you get the chance.

First of all, thank you very much for your contribution 🙏 Also for providing screenshots and documentation, really appreciated.

I gave a first look at the code and it looks good. There are however a couple of discussion points we should solve:

• I think this can actually live into its own widget LoadableSlideToActView? This will help separate the logic of the two animations
• The widget is currently stateless. Before this PR can be merged, State management should be added.

Thanks for taking a look at my PR!

Will look into separating out the loadable code to its own LoadableSlideToActView widget, I think that's a great idea actually. I'll also implement the loading animation in this new widget and look into adding state management. Did you have a certain state management design/architecture in mind or are you happy with me sending you an update to this PR including proper state management for you to review?

Nothing specifically at the moment. Eventually a solution that relies on getDrawableState + some custom states could be interesting. Otherwise anything that is able to retain the state of the widget on configuration change would also work 👍
