What is right way to do it?

Answer 1

To override the backgroundColor, you could just do this:

<Image
style={[ styles.CircleShapeView, { backgroundColor: "#fff" } ]}                   
...
/> 

A more flexible way of overriding style would be to pass an additional style prop to your subcomponent.

You would call your subcomponent like that:

<Subcomponent passedStyle={{ backgroundColor: '#fff' }} /> 

Apply passed style to your image:

<Image
style={[ styles.CircleShapeView, this.props.passedStyle ]}                   
...
/>
