Now if you scroll up out of the end threshold and then back down into it,
onEndReached will get triggered again. This closes https://github.com/facebook/react-native/issues/1967
This also resets onEndReached when the data source changes. This would fix
issues where the data source changes and onEndReached should fire again since
the new data may have more pages, whereas the old data had reached the end and
stopped.

Summary: public
In Navigator, there are several places that mutate `this.state.presentedIndex`
with the express `this.state.presentedIndex = destIndex` instead of calling
`this.setState`, which creates the problem that not all internal states are
updated within the same React update cycle.
One of the symptoms is that over-swiping within the Navigator may throw JS error
due to `this.state.sceneConfigStack` and `this.state.presentedIndex` are not both
updated.
The workaround is to bypass the over-swiping gesture to avoid JS error.

Summary:
When mutation of a stack happens, we'd like to compute the diff of the stacks (before and after) so that
we can know which routes are removed in the new stack.
This diff adds a new method `substract` which does what we need.
Summary:
Disabling the scene this way would make the scene height go to zero and mess up the scroll position. By setting the bottom to the same distance, the view does not get resized and the scroll position is preserved through a scene disable cycle.
Summary:
# Summary
Add a method `keyOf` to NavigationRouteStack.
The method `keyOf` returns a key that is associated with the route.
The a route is added to a stack, the stack creats an unique key for it and
will keep the key for the route until the route is rmeoved from the stack.
The stack also passes the keys to its derived stack (the new stack created by the
mutation API such as `push`, `pop`...etc).
The key for the route persists until the initial stack and its derived stack no longer
contains this route.
# Why Do We Need This?
Navigator has needs to use an unique key to manage the scenes rendered.
The problem is that `route` itself isn't a very reliable thing to be used as the key.
Consider this example:
```
// `scene_1` animates into the viewport.
navigator.push('scene_1');
setTimeout(() => {
// `scene_1` animates off the viewport.
navigator.pop();
}, 100);
setTimeout(() => {
// Should we bring in a new scene or bring back the one that was previously popped?
navigator.push('scene_1');
}, 200);
```
Because we currently use `route` itself as a key for the scene, we'd have to block a route
until its scene is completely off the components tree even the route itself is no longer
in the stack otherwise we'd see strange animation of jumping scenes.
# What's Next
We're hoping that we can build pure reactive view for NavigationRouteStack easily.
The naive implementation of NavigationRouteStackView may look like this:
```
class NavigationRouteStackView {
constructor() {
this.state = {
staleScenes: {},
};
}
componentWillReceiveProps(nextProps) {
if (nextProps.stack !== this.props.stack) {
var stale;
var staleScenes = {...this.state.staleScenes};
this.props.stack.forEach((route, index, key) => {
if (nextProps.stack.keyOf(route) !== key) {
stale = true;
staleScenes[key] = {route, index, key, stale};
}
});
if (stale) {
this.setState({
staleScenes,
});
}
}
}
render() {
var scenes = [];
this.props.stack.forEach((route, index, key) => {
scenes.push({route, index, key});
});
Object.keys(this.state.staleScenes).forEach(key => {
scenes.push(this.state.staleScenes[key]);
});
scenes.sort(stableSortByIndex);
return <View>{scenes.map(renderScene)}</View>;
}
}
```
Summary:
If user taps the back button quickly, the app crashes becuase "pop"
internally only checks `this.state.presentedIndex` which does not
always update when transtion happens.
This diff addresses this issue.
Summary:
Hides disabled scenes using `top` instead of `left`, which fixes a bug with the native UITabBar. When the UITabBar's width is zeroed because the scene has `left: SCREEN_WIDTH, right: 0` applied, this triggers a bug with the kerning of the tab titles. Instead, zeroing the height by setting `top: SCREEN_HEIGHT` avoids the bug.
Also applies `pointerEvents="none"` to disabled scenes so that views in the off-screen scenes definitely don't receive touches, which was occurring before.

onItemRef is old and no longer needed now that the parent renders the scenes. This removes it from Navigator and all of our clients.
This is a breaking change to users of Navigator, but it is easy to transition to a ref in renderScene instead
Summary:
While adeveloper requests the emitter to emit an event, the emitter
may not emit the event immediately instead of putting the request
into a queue and process it later.
This diff allows the developer to provide a callback which will be called
when the event has been emitted.
For instance:
```
class NavigationContext {
push(nextRoute) {
var nextStack = this._stack.push(nextRoute);
this.emit(
'change',
{
reason: 'push',
nextStack: nextStack,
nextRoute: nextRoute,
},
this._onPush
);
}
_onPush(event){
if (event.defaultPrevented) {
return;
}
this._stack = event.nextStack;
this.emit('change');
}
}
```
Summary:
idStack is going away soon. This removes all references to it. Looking at the internal state of navigator will make you have a bad time.
The biggest change is switching to the new component-freezing techinique in the navigation bars. This way we avoid dependence on the idStack to provide a scalar ID for each route.
Summary:
Infinite scrolling in horizontal ListViews. Rather than just using height and Y offset to determine when to load more rows, it checks `props.horizontal` and switches between width/height and offset X/Y accordingly.
This changed required some renaming. However, the only change external to `ListView.js` is exporting `contentSize` instead of `contentHeight` from the `getMetrics()` function. (This is not part of the API, but is used "for perf investigations or analytics" and isn't reference in the repo).
I believe this change works as expected (and the xcode tests pass) though it's possible that there may more complexity in this issue that I have overlooked.

Summary:
When composing scroll views, `this.refs[SCROLLVIEW_REF]` may refer to another higher-order scroll component instead of a ScrollView. This can cause issues if you expect to need it to be a ScrollView backed by an RCTScrollView.
The solution is to call `getScrollResponder()` - as long as all higher-order scroll components implement this method, it will make its way down to the true ScrollView, which is what ListView wants here.

Summary:
Introducing the data structure NavigationRouteStack that focused on managing
navigation routes stack.
The goal is to make <Navigatior /> thinner by moving stack management logic into
its own class and make sure it's well-tested.
Teh next step will be cleaning up <Navigatior /> and add `NavigationRouteStack` to
`NavigationContext`.
Summary:
A minor improvement suggestion: `Navigator.getCurrentRoutes()` probably shouldn't return its `routeStack` backing array as-is, because the caller may mutate it, causing the internal state of the navigator to go out of sync. Instead a shallow copy of the routes should be returned.
I stumbled on this problem in my app by attempting to read the navigator state as follows:
```
let routes = Navigator.getCurrentRoutes();
let current = routes.pop();
let previous = routes.pop();
```
Which led to an exception at next navigation event.

Summary: At the moment the `ListView.js` `_childFrames` variable is only updated on scroll. As a consequence, `onChangeVisibleRows` won't get triggered for the initial render, nor any future render not trigered by scroll events. To fix this we need to make sure native and JS have the child frames in sync.
Summary:
When `UIManager.measure` is called from `componentDidMount` it causes the error "Attempted to measure layout but offset or dimensions were NaN". Deferring the layout by one frame solves this problem. Layout measurement is already asynchronous anyway, so I believe adding the `requestAnimationFrame` call doesn't affect the program's correctness.

API that makes it really hard for the descendent children of a navigator to observe its focus
change events.

Since for now the descendent children do have access to the navigator via `this.props.navigator`,
this diff makes it easy to observe the focus change event by doing:
```
this.props.navigator.addListener('willfocus', this._onFocus);
```
The goal is to make the event system in navigator more useful and maintainable.
Test Plan:

Summary:
When a new data source is provided, update `curRenderedRowsCount` in addition to `prevRenderedRowsCount`. What was happening is that I had an empty data source, so `curRenderedRowsCount` and `prevRenderedRowsCount` both settled at zero after the first few frames and `curRenderedRowsCount` wasn't getting increased when the data source was updated.
I also changed the `setState` calls to use the transactional API since several of the new state values are computed from the old ones.

Summary:
Navigator overrides the `ref` prop of scene components so that it can call `onItemRef` and do internal bookkeeping. With callback refs, we can additionally call the original value of the `ref` prop as long as it's a function (that is, string refs are not supported). Note that the `ref` prop is moved to `reactElement.ref` out of `reactElement.props.ref`, which is why this diff accesses `child.ref`.
This diff adds support for callback refs and warns helpfully if a string ref was provided. It should be completely backwards compatible since scenes couldn't have been relying on the `ref` prop before.

Summary:
Scenes with 0 opacity are being rendered on top of other scenes with full absolute positioning. On iOS this is fine, because the platform will not send touch events to a view with no opacity.

Summary:
Now you can pass a route to the pop function in the navigator context, and the Navigator will pop that scene off the stack and every scene that follows.

As it was implemented, the jsdoc parser would look only the first non-blank line immediately preceding a function declaration. However, the line that was set as the beginning of a function declaration was where the opening bracket (`{`) was. This is insufficient for functions whose definitions span multiple lines. For example, this declaration would not find the comments above it:
```
/**
* Clones rows
**/
cloneWithRows(
dataBlob: Array<any> | {[key: string]: any},
rowIdentities: ?Array<string>
): ListViewDataSource {
...
}
```
With this change, the parser will first check if we have a closing parenthesis. If we do and don't have a matching open parenthesis we continue moving up the lines until we find it. Then we set previous line to be the line before that, the true beginning of the function declaration.
