用法

指示点

没有子元素的徽章会渲染为一个小圆点指示器。

BadgeDot.tsx

import { Host, Badge } from '@expo/ui/jetpack-compose';

export default function BadgeDot() {
  return (
    <Host matchContents>
      <Badge />
    </Host>
  );
}

带计数的徽章

传入一个 Text 子元素来显示数字或标签。

BadgeCount.tsx

import { Host, Badge, Text } from '@expo/ui/jetpack-compose';

export default function BadgeCount() {
  return (
    <Host matchContents>
      <Badge containerColor="#EF5350" contentColor="#FFFFFF">
        <Text>3</Text>
      </Badge>
    </Host>
  );
}
