forwardRef in decorator connect Error

[xuanheScript]

version: "react-redux": "6.0.1"
It Error:
@connect(mapStateToProps,mapDispatchToProps,null,{ forwardRef: true }) Component export default Component
It Correct:
export default connect(mapStateToProps,mapDispatchToProps,null,{ forwardRef: true })(Component)

Error Message: Expected a constructor

Why?

Sorry, we don't support or recommend using connect as a decorator. If it works, that's great, but it's not an intentionally supported use case since the decorator spec and plugins continue to change.
