} from 'react-flow-builder';

import './index.css';

  const node = useContext(NodeContext);
  return <div className="start-node">{node.name}</div>;
};

const EndNodeDisplay: React.FC = () => {
  const node = useContext(NodeContext);
  return <div className="end-node">{node.name}</div>;
};

const OtherNodeDisplay: React.FC = () => {
  const node = useContext(NodeContext);
  return <div className="other-node">{node.name}</div>;
};

const ConditionNodeDisplay: React.FC = () => {

  return <div className="condition-node">{node.name}</div>;
};

const registerNodes: IRegisterNode[] = [
