v1.0.0-beta.6

NestedScrollView is now on different package, it was a huge codebase dependency, and it was not required to work with the bottom sheet, also a little bit hard to maintain, it is only useful when you are NOT using the anchor point.

See the repository: https://github.com/cesardeazevedo/react-native-nested-scroll-view

If you are using the NestedScrollView, you should now attach it on the componentDidMount as follows.

import NestedScrollView from 'react-native-nested-scroll-view'

class App extends Component {
  componentDidMount() {
    this.bottomSheet.attachNestedScrollChild(this.nestedScroll)
  }
  render() {
    return (
      <CoordinatorLayout>
        <BottomSheetBehavior ref={ref => { this.bottomSheet = ref}}>
          <NestedScrollView ref={ref => { this.nestedScroll = ref }} />
        </BottomSheetBehavior>
      </CoordinatorLayout>
    )
  }
}
