Stack two buttons like in a horizontal UIStackView in React Native - ios

Question

I have a login form with two text inputs stacked vertically and a container view with two buttons below the inputs:
I want the two buttons to stretch to fill the width of the button container (red), so each button would take half its size. However I can't get it to work. I've tried various combinations of flex* properties with no luck.
In native iOS I would use a UIStackView for this with orientation = horizontal. React Native documentation says that pretty much any layout can be achieved with flexbox.
This is what my component looks like right now:
import React, {Component} from 'react';
import {KeyboardAvoidingView, TextInput, View, StyleSheet} from 'react-native';
import Button from 'react-native-button';
export default class Login extends Component {
render() {
return (
<KeyboardAvoidingView style={styles.container}>
<TextInput
placeholder="LOGIN"
placeholderTextColor="#505050"
style={styles.input}/>
<TextInput
placeholder="PASSWORD"
placeholderTextColor="#505050"
style={styles.input}/>
<View style={styles.buttonContainer}>
<Button
onPress={() => this.logIn()}
style={[styles.button, styles.loginButton]}>
Log in
</Button>
<Button
onPress={() => this.register()}
style={[styles.button, styles.registerButton]}>
Register
</Button>
</View>
</KeyboardAvoidingView>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
paddingHorizontal: 16,
backgroundColor: 'lightgray'
},
input: {
height: 40,
marginBottom: 12,
paddingHorizontal: 8,
backgroundColor: 'white'
},
buttonContainer: {
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: 'red'
},
button: {
padding: 8,
color: 'white',
backgroundColor: 'steelblue'
},
loginButton: {
marginRight: 8
}
});
If I add flex: 1 to the button style they become:
What am I doing wrong?

Yes. Its because of the react-native-button component. You have to use the containerStyle property of the Button component to style the container.
import React, {Component} from 'react';
import {KeyboardAvoidingView, TextInput, View, StyleSheet} from 'react-native';
import Button from 'react-native-button';
export default class Login extends Component {
render() {
return (
<KeyboardAvoidingView style={styles.container}>
<TextInput
placeholder="LOGIN"
placeholderTextColor="#505050"
style={styles.input}/>
<TextInput
placeholder="PASSWORD"
placeholderTextColor="#505050"
style={styles.input}/>
<View style={styles.buttonContainer}>
<Button
onPress={() => this.logIn()}
style={styles.buttonText}
containerStyle={styles.button}
>
Log in
</Button>
<Button
onPress={() => this.register()}
style={styles.buttonText}
containerStyle={styles.button}
>
Register
</Button>
</View>
</KeyboardAvoidingView>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
paddingHorizontal: 16,
backgroundColor: 'lightgray'
},
input: {
height: 40,
marginBottom: 12,
paddingHorizontal: 8,
backgroundColor: 'white'
},
buttonContainer: {
height: 60,
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: 'red'
},
button: {
flex: 2,
padding: 8,
backgroundColor: 'steelblue',
alignSelf: 'stretch',
justifyContent: 'center',
},
buttonText: {
color: 'white',
}
});
