Eli White a3c07c95ef StyleObj -> DangerouslyImpreciseStyleProp
Summary:
Migrating everything to import from StyleSheet instead of StyleSheetTypes.

Search and replaced
```
import type {StyleObj} from 'StyleSheetTypes';
```
to
```
import type {DangerouslyImpreciseStyleProp} from 'StyleSheet';
```

and then replacing `StyleObj` with `DangerouslyImpreciseStyleProp` and fixing up the remaining flow errors by hand.

Taylor Kline 82b4b9b115 Give complex FlatList example more motivation
Summary:
Previously, the example MyListItem never referenced the selected prop, leaving ambiguity about the intention of the demo.

By adding a concrete implementation with coloring based on the selected prop, we can see that this is a demo of a multi-select list for batch actions instead of, say, a click-to-navigate nested list.

Here is a working Snack demo for future reference:

Rene Weber 75508c12ff Add setNativeProps
Summary:
Curently FlatList does not implement setting native props directly like the old ListView did. This pr introduce the `setNativeProps` function which delegates to MetroListView or VirtualizedList. Thos don't have `setNativeProps` handling either, so, I delegated further to the respective ListView and Scroll components, which do have handling for it, thus, allowing to set the native props through FlatList.

Create a project with a FlatList and change a native property using `setNativeProps`:

```javascript
  componentDidMount() {
        setInterval(() => {
            this.list.setNativeProps({ style: {backgroundColor:"white"} })
        }, 1000)
    }

  render() {
    return (
      <View style={styles.container}>
        <FlatList ref={component => this.list = component}
                  style={{backgroundColor:"black"}}
                  data={[{key: 'a'}, {key: 'b'}]}
                  renderItem={({item}) => <Text>{item.key}</Text>} />
      </View>
    )
  }
```

Louis Lagrange 264d67c424 Add ListEmptyComponent prop
Summary:
Hey there :)

Please let me know if the name `ListEmptyComponent` should be changed. I also thought about `ListNoItemsComponent`. Or maybe `ListPlaceholderComponent`?

- [x] Explain the **motivation** for making this change.
- [x] Provide a **test plan** demonstrating that the code is solid.
- [x] Match the **code formatting** of the rest of the codebase.
- [x] Target the `master` branch, NOT a "stable" branch.

In a FlatList, I wanted to show some placeholder when my data is empty (while keeping eventual Header/Footer/RefreshControl).
A way around this issue would be to do something like adding a `ListHeaderComponent` that checks if the list is empty, like so:
```js
ListHeaderComponent={() => (!data.length ? <Text style={styles.noDataText}>No data found</Text> : null)}
```
But I felt it was not easily readable as soon as you have an actual header.

This PR adds a `ListEmptyComponent` that is rendered when the list is empty.

I added tests for VirtualizedList, FlatList and SectionList and ran `yarn test -- -u`. I then checked that the snapshots changed like I wanted.
I also tested this against one of my project, though I had to manually add my changes because the project is on RN 0.43.

Here are the docs screenshots:

* In **VirtualizedList**, changed the `getItem` and `getItemCount` props from optional to required, and removed default values.
* Ensured that implementing classes **FlatList** and **SectionVirtualizedList** are always passing these props.
* Updated VirtualizedList-test.js accordingly.

Spencer Ahrens 28aaa88808 Many improvements
Summary:
These got smashed together with some weird rebase snafu. They are pretty intertwined anyway so the value of
separate commits is minimal (e.g. separate commits would not revert cleanly anyway).

== [lists] better fill rate logging (previously D4907958)

After looking through some production data, I think this will address all the issues we're seeing. Now:

- Header/Footer getting no longer counted as blank.
- Avoid floating point for Scuba.
- Compare actual time of blankness, not just samples.
- Include both "any" vs. "mostly" blank (similar to 1 and 4 frame drops).
- Include events where there is no blankness so we have a baseline.
- Remove events with too few samples

**Test Plan: **

A bunch of scrolling in FlatListExample

T17384966

== [Lists] Update SectionSeparatorItem docs (previously D4909526)

Forgot to update the language here when we modified the behavior with the introduction of separator
highlighting support.

** Test Plan: **
nope.

== [Lists] Add renderSectionFooter prop to SectionList (previously D4923353)

Handy for things like "see more" links and such.

The logic here is to render the footer last, *after* the bottom section separator. This is to preserve
the highlighting behavior of the section separator by keeping it adjacent to the items.

**Test Plan: **
Added to snapshot test and example:

{F66635525}

{F66635526}

== [SectionList] Add a bunch more info for rendering items and separators (previously D4923663)

This extra info can be helpful for rending more complex patterns.

**Test Plan: **
Made snapshot test more comprehensive and inspected the output.

== [Lists] reduce render churn (previously D4924639)

I don't think the velocity based leadFactor is helping and might actually be hurting because
it causes a lot of churn in the items we render.

Instead, this diff introduces fillPreference which biases the window expansion in the direction of scroll,
but doesn't actually affect the final bounds of the window at all, so items that are already rendered are
more likely to stay rendered.

**Test Plan: **

Played around in debug mode and watched the overlay - seems better. Also tests all pass.

T16621861

== [Lists] Add initialScrollIndex prop

Makes it easy to load a VirtualizedList at a location in the middle of the content without
wasting time rendering initial rows that aren't relevant, for example when opening an infinite calendar
view to "today".

**Test Plan: **
With debug overlay, set `initialScrollIndex={52}` prop in `FlatListExample` and
and see it immediately render a full screen of items with item 52 aligned at the top of the screen. Note
no initial items are mounted per debug overlay. Scroll around a bunch and everything else seems to work
as normal.

No SectionList impl since `getItemLayout` isn't easy to use there.

Spencer Ahrens f25df504ed Add support for updating adjacent separators on row highlight to FlatList
Summary:
A nice bit of polish for apps is to update the separators between list items
when press actives the highlight (things get especially noticeable/ugly when
the separators are not full width and don't adjust). This can be difficult to
coordinate and update efficiently, so we bake the functionality into
`VirtualizedList`.

The approach taken here is a little different from `ListView`. We pass a new
`separators` object with `renderItem` that has easy-to-use callbacks for toggling
the 'highlighted' prop on both adjacent separators - they can be wired up
directly to the `onShow/HideUnderlay` props of `TouchableHighlight` (pit of
success and all that - we want those RN apps to be polished!), but we also
provide a more generic `separators.updateProps` method to set any custom
props. This also passes in `leadingItem` so more custom wiring can be done on
initial render (e.g. linking the highlight state with `Animated`).

This also moves the separator rendering into the `CellRenderer`. I think this might
also fix some subtle measurement bugs with the `onLayout` not capturing the
height of the separator, so that's nice too, but the main reason is to have
an easy place to store the state so we don't have to re-render the entire list
like `ListView` does. Instead we track references to the cells and call update
only on the two we care about so the feedback is instantaneous even with big,
heavy lists.

This diff also messes with a bunch of flow and updates the example to be more
like a standard list.

`SectionList` support is coming in a stacked diff.

Pretty sure this is backwards compatible....

Spencer Ahrens ecf4c48966 Add `scrollToLocation` for `SectionList`
Summary:
Basic functionality that takes `itemIndex` and `sectionIndex`

**TestPlan**

Added this to onChangeText:

	this._listRef.getNode().scrollToLocation({itemIndex: 6, sectionIndex: 3, viewOffset: 25});

and saw it scroll to the correct position right under the sticky header.

Spencer Ahrens 87bdcbde6a propagate getScrollResponder, getScrollableNode
Summary:
so users can call `setNativeProps` and do more compositing.

**Test Plan:**

Added this to `onPress` of `SectionListExample` and `FlatListExample`:

    this._listRef.getNode().getScrollResponder().setNativeProps({scrollEnabled: false});

and saw scroll get disabled. Note the call to `getNode` because we are using the `Animated.createComponent` wrapper.

Summary: it's possible to update data and not have the content length change, which could prevent onEndReached from ever firing again, so fix that.
