Previously we had been emiting an action event with a null state when the router handles the action by returning null from getStateForAction.
- Fixes the case of null state getting emitted
- Renames a few things for clarity
- Refactors conditionals to read easier
- Comments to explain intent
* 3127: Fixed gestureDirectionInverted variable declaration and condition in onPanResponderMove method in regards to swipe back action in RTL mode.
* - 4118: Put axis check first;
- Fixed default BackButton mask in RTL mode.
“reset” is not a NavigationAction anymore.
The correct fix, for v3, to this is to navigate to the first screen inside the stack. With the less-pushy navigate behavior in v2, this will result in the first route getting selected if you specify it by routeName.
* Use Array.prototype.findIndex instead of map => indexOf
Creating a new array and iterating over all the routes is inefficient compared to findIndex, which does not create a new array and exits as soon as it finds a match. Since the indexOf method is used extensively this should provide a minor performance improvement
* reverted yarn.lock edits
* don’t use private global
* add missing method ‘getParam’ to navigation screen prop
* correct return type for ‘withNavigation’
* add usage of `getParam` method
* Make StackNavigator keyboard aware
One thing that has always annoyed me in React Navigation is the handling of the keyboard. When a keyboard is visible on screen and a navigation action occurs (either by tapping a button or using a gesture), the keyboard tends to stay on screen until the transition completes. This feels janky and broken. On native iOS, for instance, the keyboard hides immediately when the navigation starts, and if the transition is cancelled (say, when the user releases the gesture), the keyboard reappears.
This PR introduces a "KeyboardAwareNavigator" higher order component that is enabled on the StackNavigator, unless a `disableKeyboardHandling` prop is passed into the StackNavigator's configuration.
* Set status bar in keyboard handling example
* Call gesture props in keyboard aware navigator if available
* Fix formatting
