onPull React Native ScrollView

Question

• What is the pull Props in ScrollView ?

Or in other words

• Which Prop should run when we get to the first item in ScrollView ?

For example

 <ScrollView
      scrollEnabled={this.state.scrollEnabled}
      onScroll={(y) => {
          if (y.nativeEvent.contentOffset.y <= 0 ) {
               // 
           }

I'm not completely sure what you're trying to achieve, but I think you're looking for the refreshControl prop.

See the docs: https://facebook.github.io/react-native/docs/scrollview#refreshcontrol
