How to create a custom Icon component based on NativeBase.Icon that accepts a 'iconFamily' parameter

MyIcon.js

import React from 'react'
import PropTypes from 'prop-types'
import {Icon, StyleProvider, getTheme } from 'native-base';

class MyIcon extends React.Component {
  render() {
    if(this.props.iconFamily) {
      return (
        <StyleProvider style={getTheme({iconFamily: this.props.iconFamily})}>
          {this._renderIcon()}
        </StyleProvider>
      )
    } else {
      return this._renderIcon();
    }
  }

  _renderIcon() {
    const {['iconFamily']: _, ...newProps} = this.props;
    return (
      <Icon {...newProps} />
    )
  }
}

MyIcon.propTypes = {
  ...Icon.propTypes,
  iconFamily: PropTypes.string,
};

export default MyIcon
