How to use the @jsonforms/core.getData function in @jsonforms/core

get data() {
    return getData(this._store.getState());
  }

const mapStateToProps = (state: any) => {
  const examples = state.examples.data;

  return {
    dataAsString: JSON.stringify(getData(state), null, 2),
    examples,
    selectedExample,
    extensionState
  };
};
