Are default props available in React Native and if yes for what are they used and how are they used?

Yes, default props available in React Native as they are for React, If for an instance we do not pass props value, the component will use the default props value.

import React, {Component} from 'react';

import {View, Text} from 'react-native';
class DefaultPropComponent extends Component {
   render() {
       return (
           <View>
             <Text>
              {this.props.name}
            </Text>
          </View>
       )
   }
}
Demo.defaultProps = {
   name: 'BOB'
}

export default DefaultPropComponent;?
