React Native如何添加动态圆形边框，如whatsapp状态

import React from 'react';
import { View, StyleSheet } from 'react-native';

const CircleBorder = ({ size, color }) => {
  const circleStyle = {
    width: size,
    height: size,
    borderRadius: size / 2,
    borderColor: color,
    borderWidth: 2,
  };

  return <View style={[styles.circle, circleStyle]} />;
};

const styles = StyleSheet.create({
  circle: {
    justifyContent: 'center',
    alignItems: 'center',
  },
});

const App = () => {
  return (
    <View style={styles.container}>
      <CircleBorder size={100} color="red" />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});
