Styling Options

You can style the navigator appearance and behavior by passing an options object. This object can be passed when the screen is originally created; can be defined per-screen by setting static get options() on the screen component; and can be overridden when a screen is pushed.

The easiest way to style your screen is by adding static get options() to your screen React component definition.

export default class StyledScreen extends Component {
  static get options() {
    return {
      topBar: {
        title: {
          text: 'My Screen'
        },
        drawBehind: true,
        visible: false,
        animate: false
      }
    };
  }

  constructor(props) {
    super(props);
  }
  render() {
    return (
      <View style={{flex: 1}}>...</View>
     );
  }

Enabling persistent styling properties

In v2 we added setDefaultOptions API for styles that should be applied on all components.

Navigation.setDefaultOptions({
  topBar: {
    visible: false
  }
});

Setting styles dynamically

Use the mergeOptions method to change a screen’s style dynamically.

Navigation.mergeOptions(this.props.componentId, {
  topBar: {
    visible: true
  }
});

Options object format

iOS specific options

{
  statusBar: {
    hideWithTopBar: false,
    blur: true
  },
  popGesture: true,
  backgroundImage: require('background.png'),
  rootBackgroundImage: require('rootBackground.png'),
  topBar: {
    translucent: true,
    transparent: false,
    noBorder: false,

}

Android specific options

{
  statusBar: {
    backgroundColor: 'red'
  },
  topBar: {
    height: 70, // TopBar height in dp
    borderColor: 'red',
    borderHeight: 1.3,
    elevation: 1.5, // TopBar elevation in dp
    title: {
      height: 70 // TitleBar height in dp
    }
  },
  bottomTabs: {
    titleDisplayMode: 'alwaysShow' | 'showWhenActive' | 'alwaysHide' // Sets the title state for each tab.
  }
}

Styling the StatusBar

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.

Custom fonts

If you’d like to use a custom font, you’ll first have to edit your project.

• Android - add the .ttf or .otf files to src/main/assets/fonts/

• iOS - follow this guide

Customizing screen animations

Animation used for navigation commands that modify the layout hierarchy can be controlled in options. Animations can be modified per command and it’s also possible to change the default animation for each command.

Animation properties

The following properties can be animated:

• x
• y
• alpha
• scaleX
• scaleY
• rotationX
• rotationY
• rotation

{
  from: 0, // Mandatory, initial value
  to: 1, // Mandatory, end value
  duration: 400, // Default value is 300 ms
  startDelay: 100, // Default value is 0
  interpolation: 'accelerate' | 'decelerate' // Optional
}

For example, changing the animation used when the app is first launched:

Navigation.setDefaultOptions({
  animations: {
    startApp: {
      y: {
        from: 1000,
        to: 0,
        duration: 500,
        interpolation: 'accelerate',
      },
      alpha: {
        from: 0,
        to: 1,
        duration: 400,
        startDelay: 100,
        interpolation: 'accelerate'
      }
    }
  }
});

Customizing navigation commands animation

Animations for the following set of commands can be customized

• startApp
• push
• pop
• showModal
• dismissModal

Customizing stack command animation

When pushing and popping screens to and from a stack, you can control the TopBar, BottomTabs and actual content animations as separately.

animations: {
  push: {
    topBar: {
      id: 'TEST', // Optional, id of the TopBar we'd like to animate.
      alpha: {
        from: 0,
        to: 1
      }
    },
    bottomTabs: {
      alpha: {
        from: 0,
        to: 1
      }
    },
    content: {
      alpha: {
        from: 0,
        to: 1
      }
    }
  }
}
