Simple example of an ExRoute object

HomeRoute.js

let homeRoute = {
  getSceneClass() {
    return require('./HomeScreen');
  },
  
  getTitle() {
    return 'Home',
  },
  
  renderLeftButton(navigator) {
    return (
      <TouchableOpacity
        touchRetentionOffset={ExNavigator.Styles.barButtonTouchRetentionOffset}
        onPress={() => navigator.push(getSettingsRoute())}
        style={ExNavigator.Styles.barLeftButton}>
        <Text style={ExNavigator.Styles.barLeftButtonText}>Settings<Text/>
      </TouchableOpacity>
    );
  },
  
  renderRightButton(navigator) {
    return (
      <TouchableOpacity
        touchRetentionOffset={ExNavigator.Styles.barButtonTouchRetentionOffset}
        onPress={() => navigator.push(getHelpRoute())}
        style={ExNavigator.Styles.barRightButton}>
        <Text style={ExNavigator.Styles.barRightButtonText}>Help<Text/>
      </TouchableOpacity>
    );
  },
  
  configureScene() {
    return ExNavigator.SceneConfigs.FloatFromRight;
  },
};

Typo on lines 16 and 27. Should be </Text> instead of <Text/>.
