UIW for React Native

Flex Flex布局
---

Flex 是 React Native CSS flex 布局的一个封装。

## 基础示例

```jsx
import { Fragment } from 'react';
import { Flex, Button } from '@uiw/react-native';

function Demo() {
  return (
    <Fragment>
      <Flex>
        <Flex.Item>
          <Button size="small">按钮1</Button>
        </Flex.Item>
        <Flex.Item>
          <Button size="small">按钮2</Button>
        </Flex.Item>
        <Flex.Item>
          <Button size="small">按钮3</Button>
        </Flex.Item>
      </Flex>
    </Fragment>
  );
}
```

## 对齐方式

```jsx
import { Fragment } from 'react';
import { Flex, Button } from '@uiw/react-native';

const Circle = (props: any) => {
  const size = props.size || 20;
  const style = {
    borderRadius: size / 2,
    backgroundColor: 'red',
    width: size,
    height: size,
    margin: 1,
  };
  return <View style={style} />;
};

function Demo() {
  return (
    <Fragment>
      <Flex justify="start">
        <Circle /> <Circle /> <Circle /> <Circle /> <Circle />
      </Flex>
      <Flex justify="center">
        <Circle /> <Circle /> <Circle /> <Circle /> <Circle />
      </Flex>
      <Flex justify="end">
        <Circle /> <Circle /> <Circle /> <Circle /> <Circle />
      </Flex>
    </Fragment>
  );
}
```
