Interest in contributing: footerOptions, onBackdropPress, scrollable detection depth

[steeeeee]

Hi @lodev09! I'm integrating TrueSheet as the native bottom sheet in a React Navigation setup (New Architecture).
It's been great to work with, thanks for building this!

I've hit a few gaps where I've built local patches. Before I keep maintaining them as patch-package overrides, I'd love to contribute them upstream if you're open to PRs.

1. footerOptions to include footer in auto detent calculation

Currently the auto detent measures content + header but not the footer, since it is floating. For sticky action buttons at the bottom, the sheet ends up too short. I'd propose an optional footerOptions prop (consistent with scrollableOptions, grabberOptions, blurOptions) to opt in:

<TrueSheet footer={<MyFooter />} footerOptions={{ mode: 'fixed' }}>

• overlay (default): current behavior, non-breaking
• fixed: footer height included in auto detent, content scrolls past footer

2. onBackdropPress callback

When users tap the backdrop, there's no way to intercept it: the sheet either dismisses or ignores (if dismiss=false).
I'd like to run a callback instead of dismissing (e.g., for confirmation dialogs). Swipe-down behavior would remain unchanged.

3. Scrollable detection depth (iOS)

The docs mention scroll view detection is limited to 2 levels deep on iOS. When using design system layout wrappers, in some cases the ScrollView ends up deeper and isn't found. I noticed Android's findScrollView already searches recursively: would you be open to matching that on iOS, or would a searchDepth option in scrollableOptions be preferred?

Happy to submit these as separate PRs with tests and docs. Would you be open to contributions like these?

Hey @steeeeee, thanks for the feedback! I think these are good additions/options for flexibility.

1. For the footer, the only advantage of doing this besides appending your footer at the bottom of your content is for the keyboard integration. That being said, would be nice for you to handle the scrolling bottom inset as well.

2. for onBackdropPress, this is has been in my radar and it's actually supported natively on ios. I don't know if you could listen to actual backdrop press on ios though. I was thinking more like onDidAttemptDismiss as this is the native approach documented by apple -- just need parity on android & web.

3. Yeah, searchDepth would be nice. Might as well fix it on android to use it too.

Feel free to open PRs, separately per feature

Thanks for the super quick response @lodev09! Great to hear you're open to these.

Good point on the footer keyboard integration, I'll make sure the scroll bottom inset is handled when footer size changes.

On iOS I think we might be able to distinguish backdrop tap from swipe using the _isDragging state, will investigate during implementation, otherwise onDidAttemptDismiss sounds like a reasonable fallback.

For searchDepth, sounds straightforward, I'll make it configurable on both platforms.

I'll get back to you directly with the PRs and we can discuss more in detail 👌
