Force focus to a certain index in ListView

I create a list and depending on the input given by the user I want it to focus on a certain element in the list.

<ListView for="(item, index) in timeTable" @itemTap="onItemTap">
    <v-template>
            <FlexboxLayout class="travelDetails" :ref="index">
            </FlexboxLayout>
    </v-template>
</ListView>

created: function(){
     this.$refs[this.indexIWantToFocusOn].nativeView.focus()
}

But the problem is the reference of that element isn't rendered yet.

So is there a way to force that index should start at other value than 0?

Or Is there another way around?

You could try scrolling to the desired index after the ListView is loaded through scrollToIndex. Check the docs.

<ListView for="item in timeTable" @itemTap="onItemTap"
    ref="myList" @loaded="onLoaded">
    <v-template>
        <FlexboxLayout class="travelDetails">
        </FlexboxLayout>
    </v-template>
</ListView>

onLoaded() {
    this.$refs.myList.nativeView.scrollToIndex(this.indexIWantToFocusOn);
}
