How to use the react-md/lib/Snackbars.defaultProps function in react-md

_addToast() {
    const { text, action } = this.state;
    const toasts = this.state.toasts.slice();
    toasts.push({ text, action });

    const words = text.split(' ').length;
    const autohideTimeout = Math.max(
      Snackbar.defaultProps.autohideTimeout,
      (words / AVERAGE_WPS) * 1000
    );

    this.setState({ toasts, autohideTimeout });
  }
