To override style with React Native, we set the style prop to the styles we want by putting them in an object.

For example, we write

const styles = StyleSheet.create({
  CircleShapeView: {
    width: 50,
    height: 50,
    borderRadius: 50 / 2,
    backgroundColor: "#000",
  },
});

//...

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

to set the style prop of the image to an array with the styles object and an object with the backgroundColor we want to set.

The background color is #fff since the 2nd object has the latest backgroundColor value.
