* Update flow type definition for getParam to actually check key and
fallback are valid
* add changelog entry for `getParam` flow type changes
* Return "any" in `getParam` if params are not defined in the navigation state
* use void in place of any
React Native 0.56 introduces Flow 0.75, which makes it impossible to refine `NavigationRoute` based on the presence of `index` or `routes` properties.
This PR turns `NavigationStateRoute` and `NavigationLeafRoute` into exact types, which addresses this issue.
Unrelated change in here: typing `tabBarOnPress`'s `defaultHandler`. Wasn't sure if I should make a separate PR for a single unrelated line, let me know if you'd prefer that going forward.
* Export getNavigationActionCreators
`react-navigation-redux-helpers` generally needs to duplicate whatever `createNavigationCreator` does. As of `react-navigation@2.0`, that includes using `getNavigationActionCreators` to construct the top-level `NavigationScreenProp`.
This PR isn't strictly needed, as it's possible to import from the file directly. But that's a brittle approach, and not particularly discoverable for anybody attempting to use a "non-stateful" navigator with their state management library of choice.
* Further refinements after writing the new helper
* Final refinement of NavigationScreenProp's relationship with _DefaultActionCreators
* Resolve merge conflicts
* [flow] Remove "any" type from NavigationComponent
"any" cripples the typechecker, so it's best to avoid. It was introduced in #3392, but I don't think the intention was to keep it there.
* [flow] Remove `any` type from `createNavigator` return
And use objects with spread sub-types instead of unions for `React$ComponentType` type param
* don’t use private global
* add missing method ‘getParam’ to navigation screen prop
* correct return type for ‘withNavigation’
* add usage of `getParam` method
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.
* 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
1. Remove `NavigationComponent` from `NavigationScreenRouteConfig`. The only context `NavigationScreenRouteConfig` is used in is as an intersection with an object, and as such the only relevant portions of `NavigationScreenRouteConfig` are the object parts.
2. Add static `HEIGHT` variable to `Header` type.
3. In `NavigationContainerProps`, make `onNavigationStateChange` property value nullable.
PS: if in the future you guys would prefer that I separate these sort of PRs into their constituent parts, let me know.
* Add activeLabelStyle and inactiveLabelStyle
Adding activeLabelStyle, so that active items can be customized more.
My use case: Change font of the active item to bold.
Also, added inactiveLabelStyle which can be used for a similar purpose.
* prettier fix
* Update react-navigation.js
* prettier fix
* Update jest snapshot for DrawerNavigator - for adding a new style property to the styles array
Should be nullable, since it is initially called as `null` in `src/createNavigationContainer.js` (and in `react-navigation-redux-helpers`, where it is causing a Flow error)
* use initialRouteName as key when initializing StackRouter
* fix null headerLeft
* merge back
* fixed tests
* use config flag
* fixed snapshots
* implemented requested changes
* 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
* 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
