updating navigation parameters in react navigation - react-native

Question

I am trying to navigate to the same screen from two different place and passing different parameters to show additional contents.
Navigation code
// I am navigating to Worklogs screen from both places.
// In the first case only passing the current date as parameter
// and in the second case one extra parameter showPending
<View style={styles.row}>
// first touchable. don't want to show pending worklogs if navigated using this
<Touchable
style={styles.widgets}
onPress={() => this.navigateToScreen('Worklogs', {date: this.getToday()})}
>
<View style={{ flex: 1}}>
<View style={{ flex: 2, alignItems: 'center' }}>
<Image
source={require('../assets/images/todayworklog.png')}
style={{ resizeMode: 'contain', height: 50}}
/>
</View>
<View style={{ flex: 1 }}>
<Text> Today Worklog </Text>
<Text style={{ alignSelf: 'center', fontSize: 12, color: '#33b0df' }}>{worklogs.total_time} Hours</Text>
</View>
</View>
</Touchable>
// 2nd touchable. show pending worklogs if navigated from here
<Touchable
style={styles.widgets}
onPress={() => this.navigateToScreen('Worklogs', {date: this.getToday(), showPending: true})}
>
<View style={{ flex: 1}}>
<View style={{ flex: 2, alignItems: 'center' }}>
<Image
source={require('../assets/images/pendingworklog.png')}
style={{ resizeMode: 'contain', height: 50}}
/>
</View>
<View style={{ flex: 1 }}>
<Text> Pending Worklog </Text>
</View>
</View>
</Touchable>
</View>
// navigate to screen code
navigateToScreen(screenName, parameters) {
if(this.isEmpty(parameters)) {
this.props.navigation.navigate(screenName);
} else {
this.props.navigation.navigate(screenName, parameters);
}
}
In the render method of Worklogs screen I am checking for the showPending value to render an additional component.
const { params } = this.props.navigation.state;
{ (params && params.showPending)
? <PendingWorklogList pendingWorklogs={this.state.pending_worklogs} />
: <View />
}
Now if I navigate to Worklogs screen by tapping the first <Touchable />, showPending is not in the parameters and <PendingWorklogList /> component is not being rendered. Navigating from the 2nd <Touchable /> adds showPending to the parameters and <PendingWorklogList /> is rendered.
But if I go back and navigate to Worklogs again by tapping the first <Touchable /> the showPending parameter is still present so <PendingWorklogList /> is being rendered. But I would like to render <PendingWorklogList /> only if I navigate from the 2nd <Touchable />.
