How can I link the button outside flatlit to hide and show the items inside the flatlist in each section react native - react-native

Question

I am using flatlist in my app to show the result of the game by using API, I have a button outside the flatlist, I want the user to click the button and by clicking the button toggle switch will appear with each game and a user can switch off to hide the games and switch on to show the games.
First problem how can I link the button with the render function of flatlist to show the toggle switch.
Seconde is that how can I use the toggle switch to show and hide the games in flatlist.
<View style={{flex:1,}}>
<TouchableOpacity onPress={this.renderItem }> // What should I do here?
<Text style={{fontSize:30,color:'blue'}}>show/hide</Text>
</TouchableOpacity>
<DraggableFlatList
data={this.state.dataSource}
onDragEnd={this.dataSource}
renderItem={this.renderItem}
keyExtractor={item => item.GameId.toString()}
ItemSeparatorComponent={this.renderSeprator}
refreshing = {this.state.refreshing}
onRefresh = {this.handleRefresh}
/>
renderItem=({item,navigation,drag,btnvalue1})=>{
const current = new Date();
const currentHour = current.getHours();
return(
<ScaleDecorator>
<TouchableOpacity style={styles.item}
onLongPress={drag}
onPress={
() => this.props.navigation.navigate('ResultsStack',
{ screen: 'Result', params: { resultDate: this.state.resultDate ,GameId: item.GameId } }
//() => this.props.navigation.navigate('ResultsStack', { screen: 'Result' }
)} >
<Image style={styles.img}
