How to use the plywood.AttributeInfo function in plywood

export function getVariablesFlatDataset() {
  let attributes: Attributes = [];
  let flatDatum: Record = {};
  for (let variablesDatum of variablesData) {
    let name = variablesDatum['VARIABLE_NAME'];
    let value: any = variablesDatum['VARIABLE_VALUE'];
    let type: PlyType = 'STRING';

    // Do this crazy MySQL conversion (I am not making this up)
    if (value === 'ON' || value === 'OFF') {
      value = value === 'ON';
      type = 'BOOLEAN';
    }

    flatDatum[name] = value;
    attributes.push(new AttributeInfo({ name, type }));
  }
  return Dataset.fromJS([flatDatum]);
}

renderAttributeAdd() {
    const { onChange, dataCube } = this.props;
    const { showAddAttributeModal } = this.state;

    if (!showAddAttributeModal) return null;

    const attributes = dataCube.attributes;

    const attribute = new AttributeInfo({
      name: generateUniqueName('a', (name) => attributes.filter(a => a.name === name).length === 0 ),
      type: 'STRING'
    });

    const onSave = (attribute: AttributeInfo) => {
      onChange(dataCube.changeAttributes(dataCube.attributes.concat([attribute]).sort()));
      this.closeAttributeSuggestions();
    };

    const onAlternateClick = () => {
      this.setState({
        showSuggestionsModal: true,
        showAddAttributeModal: false
      });
    };

initFromProps(props: AttributeModalProps) {
    if (props.attributeInfo) {
      this.setState({
        newInstance: new AttributeInfo(props.attributeInfo.valueOf()),
        canSave: props.mode === 'create',
        errors: {}
      });
    }
  }
