Text selection

[amake]

There are some use cases in which it would be desirable to be able to select the text inside HighlightView.

I say some use cases, because there are also times when you don't want it selectable, so I would not advocate for making the text selectable by default.

The modern way of allowing selection is to wrap the desired widget tree in a SelectableRegion (usually via SelectionArea). Ideally users of HighlightView should be able to put a SelectionArea above HighlightView and selection should just work.

after I put the HighlightView under a SelectionArea, the text still can't be selected, why?

Because #71 needs to be merged before that can work.

this repo seems have be abandoned, any other package recommend? I just want it can highlight xml and also can copy.
