This is a utility to allow navigationOptions definition functions to access the navigation options of the active child route, which allows people to replicate the v1 behavior of deep nav configuration.
* Transitioner: Fix instantaneous transitions
The transitioner will always perform an animation on state change. Instead we should check if the navigation state is requesting a transition with isTransitioning. If not, we follow a similar codepath to transitioning, without any animation.
* Update .eslintrc
* 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
Adds a new state persistence mechanisms to all of the navigators via createNavigationContainer
There are two new props that you can provide to a navigation container: `storageKey` and `renderLoading`.
`storageKey` is the string key to be used with AsyncStorage while saving and persisting navigation state. To disable persistence, set to null.
`renderLoading` allows you to render something while the navigator re-hydrates its state and loads its initial URL. By default this returns null, but Expo users will want to render a <AppLoading /> component for smooth app launches
There is also functionality in this PR to observe errors that come from re-hydrating state, and gracefully recover by dispatching an init action.
Also this revises the init action to *reset* the navigation state, rather than preserve the previous state.
* Added possibility to provide custom header back button's image, introduced API changes: removed old prop "headerBackImage", added new prop "backImage".
* Code style fixes.
* Renamed showcase file to for more clarity; updated the prop's name as well.
* Removed listeners code from showcase screens.
* wip
* fix imports
* use stylesheet for margin
stylesheet now correct
* also remove old headerLeft
* improve header buttons color
* remove ios button margin
* Add dismiss action, made possible by getParentState
* Add dismiss to flow interface
* Don't dispatch an action on dismiss helper if no parent state
* carefullyGetParent instead of getParentState
* 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
