Unmount if hidden

[lanfr0]

Hi, I'm questioning myself whether unmounting the component when it is hidden could be useful. I mean, in some cases I would like to achieve a stateless behaviour or simply use a single Portal to render the current active bottom sheet.
I tested that If I use two or more bottom sheet with the same Portal, only the last one is displayed in the view.

What do you think about?

It's up to you. You can do that if you want. Just treat the sheet as a standard view container. It will still be up to your content/views that may cause performance issue -- not the sheet itself.

On my case, I have a wrapper component for TrueSheet and I'm only rendering it when the screen is shown (react-navigation). See this guide for reference.

is there a way to get a listener or something to only render when the sheet is presented? or i have to do it manually every time?

It will look weird if you render it after the presentation animation. You want it to render in the "background" first for smooth transition. I think the only concern on your case is to render it when "needed" to present, hence my comment above
