React Native. Best way for scroll to element inside ScrollView

I have scroll view with some component.

<ScrollView ref={ref => this.contentRef = ref}>
    <SomeComponent ref={ref => this.targetRef = ref}
</ScrollView>

What is the best way for scroll to SomeComponent but limit to ScrollView height?

My try:

if (this.contentRef && this.targetRef) {
    const UIManager = NativeModules.UIManager;
    UIManager.measure(findNodeHandle(this.contentRef), (contentX, contentY, contentW, contentH) => {
    UIManager.measure(findNodeHandle(this.targetRef), (activeStepX, activeStepY) => {
        const h = Dimensions.get('window').height;
        if (activeStepY > contentH / 2) {
        this.contentRef.scrollTo({ x: 0, y: h, animated });
        } else {
            this.contentRef.scrollTo({ x: 0, y: contentH, animated });
        };
    });
    });
};

But if target very close to screen bottom, I have empty space on bottom (sorry, I need to hide any information).

But should to look like
