Introducing a wild and hacky prototype of Transitioner 2!
- "transitionProps" concept is now identical to transitioner.state
- Far simpler state management than before
- Descriptors only, no "scenes"
- No more "position"
Also, StackView is seeing improvements:
- Easier to understand when "transition props" are just this.props
- StackView only renders the current sceen and the one before it
Currently broken:
- Interpolation configuration, beyond the first push
- Attempting to move away from getSceneIndicesForInterpolationInputRange because it works with position and it is confusing as hell, but haven't worked around it yet
- Gestures, although some "backProgress" code is in the works
- Interpolation is super buggy
- onTransitionStart/End
- Header, although a lot of code is moved over
* Lazy initialization of tabs and move contents off-screen when not active
* Make subview clipping and lazy both configurable
* Record snapshots again
* Update type definition
* Remove unused log
Previously the state was getting squashed, in this case it would destroy the routeName of the state, which was a route for the parent navigator, who could no longer render properly.
* Add Flow libdef
* Move libdef to flow folder in root
* Update libdef with some refinements discovered while writing test
Mostly refining navigator config types. In the past when we tried it we got in-repo Flow errors. With a libdef we can now assert it as true!
* Get rid of all imports in libdef and refine some types
In order to make sure that contributors don't making breaking changes to our Flow types without corresponding updates to the libdefs, we should make sure these breaking changes get caught by CI. Right now our libdefs are any-typed, but I'll put up a PR later that will refine the libdef (located at `flow-typed/npm/react-navigation_vx.x.x.js`).
* Fix SimpleTabs types
dca37627a2 broke the types, but it wasn't noticed because Flow wasn't in the CI. This fixes the types; separate PR coming to add Flow to the CI.
* Refine type of NavigationEventListener callback
Instead of typing the callback as `Function`, we're now using the precise type provided by @ericvicenti
* NavigationEventListener -> NavigationEventSubscription
* Add fbemitter, keep flow passing
* Begin support for event emitter
- Adds emitter to navigation prop
- Emits top level onAction event
- stub getChildEventSubscriber for child events
* Support navigationState.isNavigating
* Focus and blur events starting to work
- Navigation completion action wired up
- Event chaining logic built in getChildEventSubscriber
- Renamed onAction evt to ‘action’
* Wrap up events progress and testing
* Rename to isTransitioning and COMPLETE_TRANSITION
* rm accidental dependency
* Suppoert event payload type
* allow transition configuration between tabs
* we don't need to pass configureTransition to TabBarComponent
* Update TabAnimations.js
* Update TabNavigator.md
