Calling nextPage() prevPage() from outside

[antonioaltamura]

Hello, can I call nextPage() and prevPage() using a Button? Something like

<VerticalViewPager>
  <View>
    <Text>slide one</Text>
    <Button title={"Scroll down"}  [..?..]  />
  </View>
  <View>
    <Text>slide two</Text>
  </View>
</VerticalViewPager>
