add example to add image using customTitle about react-native-navbar

[Kureev]

Honestly, I haven't planned this, because I think that example with custom elements is enough to understand the idea. customTitle works totally the same as customPrev or customNext. All custom elements has a priority against usual ones. Simply put, if you specify title prop and customTitle prop, then title will be ignored.

Sure no problem. I almost got it working and its amazing. Thanks for this component.

The only problem i have though now is how to handle passProps.

In the component i handle event like this:

this.props.navigator.push({
      component: Details,
      passProps: {details: details},
});

Can you suggest ideas on how to handle this?

Ok nivermind. I figured how react-native is having it in its source code.

In the renderScene i need you use {...route.passProps}

Eg:

return (
      <View style={styles.navigator}>
        {navBar}
        <Component {...route.passProps} navigator={navigator} route={route} />
      </View>
