Support task list selection action

[moophis]

It looks like the task bullets are not selectable. Ideally, we can make each list tappable to select/unselect items and provide a callback to persist underlying content changes. Something like:

Markdown(text)
  .onTextChange { newText in // when a task item is tapped
    text = newText
  }

I would appreciate it if we're able to support this functionality. Thanks!

Hi @moophis,

The way to deal with item selection in SwiftUI is typically by providing a binding to some external state that the view will update as the user selects or deselects items. However, since a Markdown text can contain many task lists, developing an API that makes sense will take some time. That is, clients should provide a way to identify the task list, apart from the binding to the selection state.

Any suggestions or ideas for this API are welcome!

Thanks for the reply!

Maybe a quick but less efficient idea is probably to modify the text string data directly or provide a new copy to the caller (e.g., replace - [ ] a task item with - [ x ] a task item). To avoid having to parse and re-render the entire markdown text, we could probably maintain an internal state in TaskListItemView and change the selection status based on that state once it's ever toggled (otherwise we stick to the text data itself). I'm not familiar with the internal workings (maybe I need to study more) but hopefully, that will work.
