React-Native animations dont work properly after setValue - react-native

Question

I have a list of items rendered in flatlist and I'm animating each of them.
In constructor I assign values for animations
constructor(props){
super(props);
this.state = { ... };
this.height = new Animated.Value(SCREEN_WIDTH/1.8);
this.width = new Animated.Value(SCREEN_WIDTH/2.5);
}
So I render items by index to get different values of them like this:
renderStyle
if(index == 0){
return {
marginRight: SCREEN_WIDTH / 35,
marginLeft: SCREEN_WIDTH / 35,
margin: SCREEN_WIDTH / 50,
width: this.width,
height: this.height,
opacity: this.state.opacity,
borderRadius: SCREEN_WIDTH / 36,
}
}
if(index == 1){
this.height.setValue(SCREEN_WIDTH/1.5);
return {
marginRight: SCREEN_WIDTH / 35,
marginLeft: SCREEN_WIDTH / 35,
margin: SCREEN_WIDTH / 50,
width: this.width,
height: this.height,
opacity: this.state.opacity,
borderRadius: SCREEN_WIDTH / 36,
}
}
then I animate the items when user press on it. Index = 0 animates correctly but index = 1 which I set the new value is not animating at all, I dont understand whats wrong with it? Can you explain me please?
Animation function:
Animated.parallel([
Animated.timing(this.width,{
toValue: SCREEN_WIDTH/1.2,
duration: 750
}),
Animated.timing(this.height,{
toValue: SCREEN_HEIGHT/1.2,
duration: 750
}),
Animated.timing(this.state.opacity,{
toValue: 0,
duration: 750
}),
]).start(() => this.props.go(item));
setTimeout(() => Actions.video({item: item}), 800);
Render
return
(
<Animated.View pointerEvents={this.state.pointer} onLayout={({nativeEvent}) => {
this.setState({
measurements: nativeEvent.layout
})
}}>
<TouchableOpacity onPress={this.captureAnimation.bind(this, item, index)}>
<AnimatedImage source={{uri: 'http://' + item.info.picture_path}} style={this.renderStyle(index)}/>
</View>
</TouchableOpacity>
</Animated.View>
);
This is a different JS file, so flatlist is working in home page and renderItem method gets the values in this JS file to be able to animate each of it.
Edit: I found a alternative solution but anyways its not still explaining why after set value animation is not working.
