transitioner2

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

 # Navigation Playground Example

-The NavigationPlayground example app includes a variety of patterns and is used as a simple way for contributors to manually integration test changes.
+A playground for experimenting with react-navigation in a pure-JS React Native app.

 ## Usage

-```bash
-yarn # in the react-navigation root directory
-cd examples/NavigationPlayground
-yarn
-yarn start
-```
+Please see the [Contributors Guide](https://reactnavigation.org/docs/guides/contributors#Run-the-Example-App) for instructions on running these example apps.

-You can view this example application directly on Android phones by visiting scanning the QR code on [this site](https://exp.host/@react-navigation/NavigationPlayground) with the [Expo app](https://play.google.com/store/apps/details?id=host.exp.exponent&hl=en).

Eric Vicenti	0ea01673e5	transitioner2 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	2018-03-11 00:11:58 -08:00
