Moti Zilberman 7b86fa2b79 Distinguish between string/number-valued interpolation nodes at the type level
Summary:
Changelog:
[General][Fixed] - Improved Flow type inference in Animated `.interpolate()`

Improves the ergonomics of `.interpolate()` by allowing Flow to infer the correct type for `outputRange`. This is achieved by adding a new type parameter `OutputT` to `interpolate()` (and `Animated.Interpolation` and `InterpolationConfigType`), which Flow infers as either `number` or `string` based on usage.

Admittedly, at the call site, this is not that much safer compared to something like `outputRange: $ReadOnlyArray<number | string>`, but it does document the intent of the API a bit better and provide some downstream type safety. For example, we can now express `Animated.Number` (D35869375) more precisely by excluding string-valued interpolation nodes.

Summary:
Problem:
All CellRenderers rerender every time the containing VirtualizedList is rerendered. This is due to the following:
- Lambda is created for each CellRenderer's onLayout prop on every VirtualizedList render (fixed in this diff)
- CellRenderer's parentProps prop changes on every VirtualizedList render

Kacie Bawiec d754bdefc6 Fix ScrollViewStickyHeader to push up header above it
Summary:
When there are multiple sticky headers, ScrollViewStickyHeader should push up the header above it when it gets to the top.

This behavior was accidentally changed in D21948830 (https://github.com/facebook/react-native/commit/fa5d3fb6b8c561b749f3e86316d06543a52dcc1c) when this component was fixed to work in Fabric.

This diff added a new variable `_shouldRecreateTranslateY`, which determines whether the `translateY` value should be recreated on render. `_shouldRecreateTranslateY` was not being set to true during `setNextHeaderY`, so the next header's Y value was never accounted for at render.

Joshua Gross fa5d3fb6b8 ScrollViewStickyHeader: update position (translateY) in Fabric ShadowTree when scrolling stops
Summary:
In Fabric, some uses of the ScrollViewStickyHeader don't work after scrolling because even though the UI correctly reflects the translateY that the StickyHeader should be at, the underlying C++ Fabric ShadowTree doesn't have the updated parameters.

1. We add a mechanism to pass static props through to animated nodes; these get passed to the platform through the normal commit-diff process. This is to allow passing props to the platform that are also controlled by the animation. This mechanism could be reused elsewhere.
2. In ScrollViewStickyHeader, listen to updates for the translateY value and pass them to the platform when it stops changing - for Fabric only. This noops for non-Fabric since it's not necessary.

Vojtech Novak e6c7846612 allow custom StickyHeader in ScrollView-based components (#25428)
Summary:
This PR adds support for custom `StickyHeaderComponent` to be used in ScrollView (and by extension in FlatList, SectionList..).

Motivation: I've been working on a FlatList with hidable header that has a search field in it. Something like https://medium.com/appandflow/react-native-collapsible-navbar-e51a049b560a but using a FlatList w/ pull-to-refresh. The implementation can be found at https://snack.expo.io/vonovak/hidable-header-flatlist .

I used the `ListHeaderComponent` prop to render the custom header - as opposed to absolute positioning which is used in the linked article because I also need the loading indicator (I added `refreshing` and `onRefresh` for that) to show up above the header.
I proceeded by adding `stickyHeaderIndices={[0]}` to keep the header at the top, which seems to be the idiomatic way to do so. Then I added `Animated.View` with custom translation logic to the rendered header.

All appears to be working fine at the first sight - when you tap any item, you'll see it react to touch (red underlay). You'll also see the header becomes hidden if I scroll far enough and appears again after scrolling up. BUT - when you scroll down so that the header becomes hidden and tap the first visible item in the list, it will not react to touches! The reason is that `ScrollViewStickyHeader`

https://github.com/facebook/react-native/blob/9a84970c35d22b68fb3d8eac019c7f415a14c888/Libraries/Components/ScrollView/ScrollView.js#L984

has its own translation logic and when I tap onto the item at the top of the list, it seems like I'm tapping the item but I'm in fact tapping that `ScrollViewStickyHeader`.

I tried working around this by not specifying `stickyHeaderIndices={[0]}` and using `ListHeaderComponentStyle` prop (this needed some additional changes in https://github.com/facebook/react-native/blob/9a84970c35d22b68fb3d8eac019c7f415a14c888/Libraries/Lists/VirtualizedList.js#L786, and the animation is junky for some reason - as if the header always needed to "catch up" with the scroll offset, causing jitter) and `CellRendererComponent` (junky animations too), but concluded that allowing to specify custom `StickyHeaderComponent` is the cleanest way to make something like this work. I'm slightly surprised I needed to do all this to make such a usual pattern work - am I missing something?

All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream.

Summary:

I've been bothered by this issue for quite a long time, finally get some time to look into it.

I find the root cause is that after a prop of the native driven node is assigned with a plain value, if you set it to be a `Animated.Value` again , it will take no effect any more, so I just keep it be a `Animated.Value` all the time.

`value --> Animated.Value () --> value () --> Animated.Value ()`

This adds support for both automagical sticky section headers in
`SectionList` as well as the more free-form `stickyHeaderIndices` on
`FlatList` or `VirtualizedList`.

The basic concept is to take the initial `stickySectionHeaders` and remap them
to the indices corresponding to the mounted subset in the render window. The
main trick here is that the currently stuck header might itself be outside of
the render window, so we need to search the gap to see if that's the case and
render it (with spacers above and below it instead of one big spacer).

In the `SectionList` we simply pre-compute the sticky headers at the same time
as when we scan the sections to determine the flattened length and pass those
to `VirtualizedList`.

This also requires some updates to `ScrollView` to work in the churny
environment of `VirtualizedList`. We propogate the keys on the children to the
animated wrappers so that as items are removed and the indices of the
remaining items change, react can keep proper track of them. We also fix the
scroll back case where new headers are rendered from the top down and aren't
updated with the `setNextLayoutY` callback because the `onLayout` call for the
next header happened before it was mounted. This is done by just tracking all
the layout values in a map and providing them to the sticky components at
render time. This might also improve perf a little by property configuring the
animations syncronously instead of waiting for the `onLayout` callback. We
also need to protect against stale onLayout callbacks and other fun stuff.

Scroll a lot with and without debug mode on. Make sure spinner
still spins and there are no crashes (lots of crashes during development due
to the animated configuration being non-monotonic if anything stale values get
through). Also made sure that tapping a row to change it's height would
properly update the animation configurations so the collision point would
still be correct.

Spencer Ahrens 500dd2cff3 Fix bug with sticky headers that listen to onLayout
Summary:
Wrapping them in ScrollViewStickyHeader broken the onLayout and would always give y = 0
because it is now relative to the wrapper.

This uses some not-so-great react magic, but fixes the bugs with no aparent side-effects.

Note we also need to kill the StaticRenderer wrapper that ListView introduces. I think this was
probably a premature optimization anyway since there are usually not many headers and they are
usually pretty cheap to render. If people care, they can use `shouldComponentUpdate` with the
rendered components.

Spencer Ahrens 94a333a2ea Fix crash with js-based sticky headers
Summary:
We're seeing ` inputRange must be monotonically increasing -1,0,0,-33,-32 ` which happens when we
have zero height headers, wherever those come from...maybe rendering null?

The math was also off and didn't handle variable height headers correctly, and it was confusing
because it was `setNextHeaderY` with the header y _minus it's height_, which only works
if the prev height was also the same height.

Janic Duplessis 77b8c09727 Implement sticky headers in JS using Native Animated
Summary:
This re-implements sticky headers in JS to make it work on Android.

The only change that was needed was to expose a way to attach a an animated value to an event manually since we can't use the Animated wrapper and `Animated.event` to do it for us because this is implemented directly in the `ScrollView` component. Simply exposed `attachNativeEvent` that takes a ref, event name and event object mapping. This is what is used by `Animated.event`.

TODO:
- Need to check why momentum scrolling isn't triggering scroll events properly on Android.
- Remove native iOS implementation
- cleanup / fix flow

**Test plan**
Test the example list in UIExplorer, test the ListViewPaging example.
Closes https://github.com/facebook/react-native/pull/11315
