Styling the Navigator

You can style the navigator appearance and behavior by passing a navigatorStyle object. This object can be passed when the screen is originally created; can be defined per-screen by setting static navigatorStyle = {}; on the screen component; and can be overridden when a screen is pushed.

The easiest way to style your screen is by adding static navigatorStyle = {}; to your screen React component definition.

export default class StyledScreen extends Component {
  static navigatorStyle = {
    drawUnderNavBar: true,
    navBarTranslucent: true
  };
  constructor(props) {
    super(props);
  }
  render() {
    return (
      <View style={{flex: 1}}>...</View>
     );
  }

Style object format

{
  navBarTextColor: '#000000', // change the text color of the title (remembered across pushes)
  navBarBackgroundColor: '#f7f7f7', // change the background color of the nav bar (remembered across pushes)
  navBarButtonColor: '#007aff', // change the button colors of the nav bar (eg. the back button) (remembered across pushes)
  navBarHidden: false, // make the nav bar hidden
  navBarHideOnScroll: false, // make the nav bar hidden only after the user starts to scroll
  navBarTranslucent: false, // make the nav bar semi-translucent, works best with drawUnderNavBar:true
  navBarTransparent: false, // make the nav bar transparent, works best with drawUnderNavBar:true,
  topBarElevationShadowEnabled: false, // Android only, default: true. Disables TopBar elevation shadow on Lolipop and above
  navBarNoBorder: false, // hide the navigation bar bottom border (hair line). Default false
  drawUnderNavBar: false, // draw the screen content under the nav bar, works best with navBarTranslucent:true
  drawUnderTabBar: false, // draw the screen content under the tab bar (the tab bar is always translucent)
  statusBarBlur: false, // blur the area under the status bar, works best with navBarHidden:true
  navBarBlur: false, // blur the entire nav bar, works best with drawUnderNavBar:true
  tabBarHidden: false, // make the screen content hide the tab bar (remembered across pushes)
  statusBarHideWithNavBar: false // hide the status bar if the nav bar is also hidden, useful for navBarHidden:true
  statusBarHidden: false, // make the status bar hidden regardless of nav bar state
  statusBarTextColorScheme: 'dark', // text color of status bar, 'dark' / 'light' (remembered across pushes)
  statusBarTextColorSchemeSingleScreen: 'light' // same as statusBarTextColorScheme but does NOT remember across pushes
  collapsingToolBarImage: "http://lorempixel.com/400/200/", // Collapsing Toolbar image. Android only
  collapsingToolBarImage: require('../../img/topbar.jpg'), // Collapsing Toolbar image. Either use a url or require a local image. Android only
  collapsingToolBarCollapsedColor: '#0f2362', // Collapsing Toolbar scrim color. Android only
  navBarSubtitleColor: 'red', // subtitle color
  screenBackgroundColor: 'white', // Default screen color, visible before the actual react view is rendered
  orientation: 'portrait' // Sets a specific orientation to a modal and all screens pushed to it. Default: 'auto'. Supported values: 'auto', 'landscape', 'portrait'
  disabledBackGesture: false, // disable the back gesture (swipe gesture) in order to pop the top screen. Default is false. iOS Only
  screenBackgroundImageName: '<name of image in Images.xcassets>', // Optional. default screen background image. iOS only
}

Note: If you set any styles related to the Status Bar, make sure that in Xcode > project > Info.plist, the property View controller-based status bar appearance is set to YES.

All supported styles are defined here. There’s also an example project there showcasing all the different styles.
