Animate hole opacity

[dcorbin]

I would like an option to be able to animate a hole's opacity/transparency.

Hi @dcorbin!
If I understood you correctly you could try to put any animated view (for example using reanimated) with 100% height/width inside the <RNHoleView> node and animate it's opacity

Thanks. I'll give that a try.

Hi @dcorbin! If I understood you correctly you could try to put any animated view (for example using reanimated) with 100% height/width inside the <RNHoleView> node and animate it's opacity

This had no effect. It's always possible I have used Reanimated wrong, but 1) I am using to animate other components opacity that appear above the RNHoleView, and 2) shows it changing the opacity value being used.

Further thinking on your response, and I wonder if you misunderstood my goal:
My RNHoleView has this style. ```
dimmer: {
backgroundColor: 'rgba(0, 0, 0, 0.7)',
},

Where I punch a whole in it of course, the hole is appears to have opacity 0 (I see completely through it).   What I really want it to animate the opacity where the hole is punched through, going 0 -> 0.7, move the hole, and the animate it again 0.7 -> 0.

I suspect this involves changes in the native code.

@dcorbin frankly I still don't get what actually you want to animate

Okay see - in most common use case for this lib we have three things:

1. Overlay (here it's blue color with 0.5 opacity
2. Content under the hole
3. Hole rect (it's just a geometry/mask without any color/opacity in it)

Here's a little sketch explaining list above:

Opacity of which element you want to animate? Overlay or content under the hole?

Part 3. I want the hole #3 to start with similar look to #1, change it to look as it does in the picture. And then reverse that, though I suspect If I can do the first. Is that clearer, or I can try to create video?

@dcorbin much clearer thanks!
Give me some time - I'll try to figure out if it possible to achieve using current technic of "cutting" geometry from the view or maybe it's possible to make some kind of workaround
