How to access props inside rightTitle/onRight static function?

[ptquang86]

Version

• react-native-router-flux ^4.0.0-beta.21
• react-native ^0.44.3

Expected behaviour

// these are not working
// this.rightTitle = this.rightTitle.bind(this);
// rightTitle = rightTitle.bind(this);

static rightTitle = () => {
        const { shareForm: { ui: { fetching } } } = this.props;
        if (fetching) {
            return <ActivityIndicator color={colors.greeny_blue}/>
        } else {
            return <Headline style={styles.navButton}>
                <Message id='ShareForm_Details_CTA' />
            </Headline>
        }
    }

Actual behaviour

undefined is not an object '_this2.props.shareForm'

It is about javascript programming... Static function doesn't have this, just props access from function params!

i tried
static rightTitle = (params) => { ... }
but params is not a props/state
