Question: I want to call a function from a connected component using `ref`, so I used before from `withRef: true` in connected component:

```js
export default connect(
  mapStateToProps, mapDispatchToProps, null, {withRef: true}
)(InviteReceiverForm)

```

and in the presentational component:

```js
<ExampleComponent 
  ref={ cmp => { if(cmp) { this.individualSenderFormRef = cmp.getWrappedInstance() }} />

```

But after I updated to `react-redux v6`, I got this error:

`withRef is removed. To access the wrapped instance, use a ref on the connected component`

How can I use ref in `react-redux v6`?

This worked for me:

```
connect(
    mapStateToProps,
    null,
    null,
    {
      forwardRef: true
    }
  )
)(ComponentName);

```
