TypeError: this.$refs.scroll.scrollToVerticalOffset is not a function

Question

In my template I have:

<ScrollView ref="scroll" row="1" verticalAlignment="center">
  ...
</ScrollView>

In my methods I have:

scrollToBottom() {
  var scroll = this.$refs.scroll;
  scroll.scrollToVerticalOffset(scroll.scrollableHeight, true);
},

But I get an error saying:

[Vue warn]: Error in v-on handler: "TypeError: this.$refs.scroll.scrollToVerticalOffset is not a function"
