React 16 and PropTypes check

[danielesalvatore]

Hello there,
Any plan to update the component to work with React 16 and the PropTypes package?
I get the following error while I use the component.

Answer.js:43 Uncaught TypeError: Cannot read property 'bool' of undefined

The corresponding line in Answer.js and the propType check that fails

Answer.propTypes = {
  active: _react2.default.PropTypes.bool.isRequired,
  onClick: _react2.default.PropTypes.func,
  children: _react2.default.PropTypes.node.isRequired
};
