How to reuse a style into same StyleSheet

Question

I am using React Native, and I want to reuse a style within the same StyleSheet. My styles are as follows:

buttonContained: {
        borderRadius: 8,
        backgroundColor: Colors.primary,
        padding: 15,
        height: 48,
        alignItems: 'center',
        justifyContent: 'center',
    },
    buttonOutlined: {
        padding: 15,
        borderRadius: 8,
        height: 48,
        borderColor: Colors.primary,
        borderWidth: 1,
        alignItems: 'center',
        justifyContent: 'center',
    },

However, I've noticed that these two buttons share the same styles, and similar styles will be used for others that I'll create. I want to reuse styles because if the default style changes, I only need to modify it in one place.

Here's an example of what I want to do:

export const globalStyles = StyleSheet.create({
      buttonDefault: {
        borderRadius: 8,
        padding: 15,
        height: 48,
        alignItems: 'center',
        justifyContent: 'center',
    },
    buttonContained: {
        **(reuse defaultStyle here)**
        backgroundColor: Colors.primary,
    },
    buttonOutlined: {
        **(reuse defaultStyle here)**
        borderColor: Colors.primary,
        borderWidth: 1,
    },
})

Does anyone know how to accomplish this?"

Put reusable styles to one style sheet and then use that wherever needed. Something like this:

const defaultStyles = StyleSheet.create({
  buttonDefault: {
    borderRadius: 8,
    padding: 15,
    height: 48,
    alignItems: 'center',
    justifyContent: 'center',
  }
});

export const globalStyles = StyleSheet.create({
  buttonDefault: {
    ...defaultStyles.buttonDefault
  },
  buttonContained: {
    ...defaultStyles.buttonDefault,
    backgroundColor: Colors.primary,
  },
  buttonOutlined: {
    ...defaultStyles.buttonDefault,
    borderColor: Colors.primary,
    borderWidth: 1,
  },
});
