scroll to index for flat list in react-native

Two things that I can see,

You need not define string refs within

{}

. However React docs suggest you to make use of ref callback

Do it something like

<FlatList
ref={(list) => this.myFlatList = list}
data={data}
keyExtractor={this._keyExtractor}
renderItem={this._renderItem}
/>

You need to bind your function to be able to refer to the correct context

Do it like

_enableTVEventHandler = () => {
this._tvEventHandler = new TVEventHandler();
this._tvEventHandler.enable(this, function(cmp, evt) {
this.myFlatList.scrollToIndex({viewPosition: 0.5, index: 2});
}.bind(this));
}

or

constructor(props) {
super(props) ;
this._enableTVEventHandler = this._enableTVEventHandler.bind(this);
}
