[React-Native-Modal]: onBackButtonPress prop returns nothing - callback

Question

I was trying to customize my Modal with onBackButtonPress prop. To check if it worked or not, I passed a console.log to it like this:
<Modal onBackButtonPress={() => console.log('Something')}>
<NewRidesModal
//...
/>
</Modal>
But in fact, it doesn't even return anything whenever I press the Android back button.
Why is he prop not returning any value at all? Is it deprecated?

Answer 1

I use this library too react-native-modal and onBackButtonPress is working fine.
I face another issue, in my case onBackdropPress is not working, but after I fix my styling modal, everything working fine.
This is my example,
Modal js
import React, { Component } from 'react'
import { View, Text, Image, TouchableOpacity } from 'react-native'
import styles from '../styles/StyleComponentModalProduct'
import { withNavigation } from 'react-navigation'
import Price from '../../../assets/components/price/Price'
import Modal from 'react-native-modal'
class ComponentModalProduct extends Component {
constructor(props) {
super(props)
this.state = {}
}
render() {
return (
<Modal
useNativeDriver={true}
animationIn={'fadeIn'}
animationOut={'fadeOut'}
backdropColor={'rgba(0, 0, 0, 0.7)'}
backdropOpacity={0.5}
isVisible={this.props.showProduct}
onSwipeComplete={() => this.props.close()}
swipeDirection={['down']}
style={{ justifyContent: 'flex-end', margin: 0 }}
onBackButtonPress={() => this.props.close()}
onBackdropPress={() => this.props.close()}>
<View style={styles.container}>
<View style={styles.subContainer}>
<View style={styles.headerContainer}>
<TouchableOpacity
onPress={() => this.props.close()}
style={styles.closButton}
/>
<View style={styles.containerImageProfile}>
<Image
resizeMode={'contain'}
style={styles.imageProfile}
source={{ uri: this.props.selectedProduct.foto }}
/>
</View>
<View style={styles.containerProfile}>
<View style={styles.containerTextName}>
<Text style={styles.textName}>
{this.props.selectedProduct.nama_produk}
</Text>
</View>
<Price
value={this.props.selectedProduct.harga_beli}
style={styles.textProfesi}
/>
</View>
</View>
</View>
</View>
</Modal>
)
}
}
export default withNavigation(ComponentModalProduct)
Style Modal js
import { StyleSheet, Dimensions } from 'react-native'
import { color } from '../../../assets/styles/ColorList'
import {
responsiveHeight,
responsiveFontSize,
responsiveWidth
} from 'react-native-responsive-dimensions'
const windowHeight = Dimensions.get('window').height
const styles = StyleSheet.create({
container: {
justifyContent: 'flex-end',
alignItems: 'center'
},
subContainer: {
height: windowHeight / 2,
backgroundColor: color.whiteColor,
width: '100%',
borderTopRightRadius: 20,
borderTopLeftRadius: 20,
paddingHorizontal: responsiveWidth(5),
paddingVertical: responsiveHeight(3)
},
headerContainer: {
justifyContent: 'center',
alignItems: 'center'
},
closButton: {
backgroundColor: '#E7E7E7',
height: 8,
width: 100,
marginVertical: 10
},
containerImageProfile: {
marginVertical: 10,
width: '100%',
justifyContent: 'center',
alignItems: 'center'
},
imageProfile: {
height: windowHeight / 3.5,
width: '90%',
borderRadius: 20
},
containerProfile: {
justifyContent: 'center',
alignItems: 'center'
},
containerTextName: {
marginHorizontal: responsiveWidth(10),
justifyContent: 'center'
},
textName: {
fontSize: responsiveFontSize(2.5),
color: color.fontColor,
textAlign: 'center'
},
textProfesi: {
fontSize: responsiveFontSize(2.5),
color: color.fontColor,
fontWeight: 'bold'
}
})
export default styles

Answer 2

I found out that onBackButtonPress is deprecated or it was actually removed. There should some more information about this on the documentation.
