Props

Usage with react-navigation

Create a navigation element using reat-navigation:

import { StackNavigator } from 'react-navigation';

const NavigationStack = StackNavigator({
	Home: {
		screen: HomeScreen
	},
	Child: {
		screen: ChildScreen
	}
});

Render StatusBarAlert adjacent with StatusBar and NavigationStack:

<View style={styles.container}>
  <StatusBar />
  <StatusBarAlert
    visible={this.state.alert}
    message="Alert!"
    onPress={this.toggleAlert}
  />
  <NavigationStack />
</View>

See the ReactNativeStatusBarAlert directory for a complete example.

Alert stack example

Much like a route stack, you can keep an alert stack as an array of alert objects in your component's state. The StatusBarAlert will render the first alert in the stack, so that as new alerts are pushed into the stack, it will render the most recent alert. If an alert is popped from the stack, StatusBarAlert will render any remaining alerts and when the stack is empty, StatusBarAlert will hide itself. Additionally, the object spread operator ({...this.state.alerts[0]}) allows you to declare the default props for alerts in render() (e.g. backgroundColor="#3CC29E") and override those props in the alert object (e.g. backgroundColor="#FF6245").

render() {
  return (
    <View style={styles.container}>
      <StatusBarAlert
        backgroundColor="#3CC29E"
        color="white"
        visible={this.state.alerts.length > 0}
        {...this.state.alerts[0]}
      />
      <Navigator
        initialRoute={initialRoute}
        renderScene={this.renderScene}
        navigationBar={
          <Navigator.NavigationBar
            routeMapper={routeMapper}
            style={{top: -20}}
          />
        }
      />
    </View>
  )
}
showSilentAlert() {
  this.setState({
    alerts: [{
      message: 'Silent Switch ON',
      onPress: () => this.navigator.push({id: 'SilentAlert'}),
      backgroundColor="#FF6245"
    }, ...this.state.alerts]
  })
}
hideSilentAlert() {
  this.setState({
    alerts: this.state.alerts.filter(alert => alert.message !== 'Silent Switch ON')
  })
}
