Hi everyone,
Can someone help me to renderTitle from component ? I tried like this but no luck
<Scene titleStyle={styles.programTitleStyle} clone backButtonTextStyle={{color:'#231f20'}} direction="vertical" key="CarList" backTitle='' component={CarList} title="Car List" renderTitle={() => {Actions.refs.CarList.getTitle()} } />

In CarList.js
getTitle(){ return ( <Button onPress={() => {Actions.SearchModal()}} > <View> <Text> {this.props.searchTitle} </Text> </View> <View > <Text> {this.props.searchDate} </Text> </View> </Button> ) }

Tring to make my title like this link but it did not help me .
