import { Radio, RadioButton, RadioGroup } from '@uiw/react-radio';基础用法
适用广泛的基础最简单的用法，展示各种状态下的样式。```jsx mdx:preview&bg=#fff import React from 'react'; import { Radio, RadioButton } from 'uiw';
export default function Demo() { return (
<div>
<Radio value="1">Radio</Radio>
<Radio value="2" checked>选中</Radio>
<Radio value="3" disabled>禁用</Radio>
<Radio value="4" checked disabled>选中并禁用</Radio>
<Radio value="4" checked disabled>选中并禁用</Radio>
<RadioButton value="5" >RadioButton</RadioButton>
<RadioButton value="5" checked >RadioButton 选中</RadioButton>
</div>### Form 中使用 Radio
```jsx mdx:preview&bg=#fff
import React from 'react';
import { Form, Radio, RadioGroup, RadioButton, Row, Col, Button, Notify } from 'uiw';
export default function Demo() {
return (
<Form

onSubmitError={(error) => error && error.filed ? { ...error.filed } : null}
onSubmit={({initial, current}) => {
const ErrObj = {};
if (current.radioGroup === 'unknown') {
ErrObj.radioGroup = '请选择性别！';
}
if(Object.keys(ErrObj).length > 0) {
const err = new Error();
err.filed = ErrObj;
throw err;
}
Notify.success({
title: '提交成功！', description: `填写：【填写成功】！`
});
}}
