/**
|
||
* Component to control the app status bar.
|
||
*
|
||
* ### Usage with Navigator
|
||
*
|
||
* It is possible to have multiple `StatusBar` components mounted at the same
|
||
* time. The props will be merged in the order the `StatusBar` components were
|
||
* mounted. One use case is to specify status bar styles per route using `Navigator`.
|
||
*
|
||
* ```
|
||
* <View>
|
||
* <StatusBar
|
||
* backgroundColor="blue"
|
||
* barStyle="light-content"
|
||
* />
|
||
* <Navigator
|
||
* initialRoute={{statusBarHidden: true}}
|
||
* renderScene={(route, navigator) =>
|
||
* <View>
|
||
* <StatusBar hidden={route.statusBarHidden} />
|
||
* ...
|
||
* </View>
|
||
* }
|
||
* />
|
||
* </View>
|
||
* ```
|
||
*
|
||
* ### Imperative API
|
||
*
|
||
* For cases where using a component is not ideal, there is also an imperative
|
||
* API exposed as static functions on the component. It is however not recommended
|
||
* to use the static API and the component for the same prop because any value
|
||
* set by the static API will get overriden by the one set by the component in
|
||
* the next render.
|
||
*
|
||
* ### Constants
|
||
*
|
||
* `currentHeight` (Android only) The height of the status bar.
