} from 'redux-form';

interface CustomProps {
  customText: string;
}

class FormComponent extends React.Component<CustomProps & InjectedFormProps<{}, CustomProps>> {
  render() {
    const { handleSubmit, customText } = this.props;

    return (
      <form onSubmit={handleSubmit}>
        <div>
          <p>{customText}</p>
        </div>
