How to hidden the pull loading view

I user this view and pull to refresh ,and when I pull down , the circle loading view still visible even after the data has update .I don't know which parameters can hidden the circle loading view.And this is my code:

```

```

Start by tracing GiftedListView's refreshable and onFetch props, using the supplied component example and refreshData callback as entry points. Reproduce pull-to-refresh and verify that the circle loading view is hidden after updated data arrives; the issue is done when the behavior and required configuration are clear.
