How to model a button with icons in react-native

Expo has a a Button component that does what you want, styling and all:

<FontAwesome.Button name="facebook" backgroundColor="#3b5998" onPress={...}>
  Sign in with Facebook
</FontAwesome.Button>
<FontAwesome.Button name="twitter" backgroundColor="#1da1f2" onPress={...}>
  Sign in with Twitter
</FontAwesome.Button>

What it looks like running in the iOS simulator:

If you're not using Expo, study the source and create a similar component.

If you are using react-native-icons module, you can try wrap both your icon and text in a view, then use TouchableHighlight on top of it. Something like:

<TouchableHighlight onPress={()=>{}}>
     <View>
         <Icon ... />
         <Text ... />
     </View>
 </TouchableHighlight>

But it will be very easy if you use a relative new module react-native-vector-icons. You can do like:

<Icon name="facebook" style={styles.icon}>
   <Text style={styles.text}>Login with Facebook</Text>
</Icon>

I managed to do it like this. I wonder if there is a better way.

var styles = StyleSheet.create({
  btnClickContain: {
    flex: 1,
    flexDirection: 'row',
    justifyContent: 'center',
    alignItems: 'stretch',
    alignSelf: 'stretch',
    backgroundColor: '#009D6E',
    borderRadius: 5,
    padding: 5,
    marginTop: 5,
    marginBottom: 5,
  },
  btnContainer: {
    flex: 1,
    flexDirection: 'row',
    justifyContent: 'center',
    alignItems: 'stretch',
    alignSelf: 'stretch',
    borderRadius: 10,
  },
  btnIcon: {
    height: 25,
    width: 25,
  },
  btnText: {
    fontSize: 18,
    color: '#FAFAFA',
    marginLeft: 10,
    marginTop: 2,
  }
});

<TouchableHighlight
  onPress={this.onBooking} style={styles.btnClickContain}
  underlayColor='#042417'>
  <View
    style={styles.btnContainer}>
    <Icon
      name='fontawesome|facebook-square'
      size={25}
      color='#042'
      style={styles.btnIcon}/>
    <Text style={styles.btnText}>Sign In with Facebook</Text>
  </View>
</TouchableHighlight>
