# Indicator

### Intro

Displays the progress of a task or process, often used for provisioning processes

### Install

```javascript
import { Indicator } from '@nutui/nutui-react-native'
```
### Basic Usage

```SnackPlayer name=Indicator
import  React from "react";
import { Indicator, Cell, Button, Row, Col } from '@nutui/nutui-react-native';

const App = () => {
  return (
    <div className="demo">
      <Cell>
        <Indicator size={3} current={3} />
      </Cell>
      <Cell>
        <Row>
          <Col span="12">
            <Button size="small" type="primary">
              Button
            </Button>
          </Col>
          <Col span="12">
            <Indicator block align="right" size={6} current={5} />
          </Col>
        </Row>
      </Cell>
    </div>
  );
};
export default App;
```

### Block usage
When `block` is true, it will be displayed as a block-level element, and the alignment can be set through `align`

```SnackPlayer name=Indicator
import  React from "react";
import { Indicator, Cell } from '@nutui/nutui-react-native';

const App = () => {
  return (
    <div className="demo">
      <Cell>
        <Indicator block align="center" size={6} current={5} />
      </Cell>
      <Cell>
        <Indicator block align="left" size={6} current={1} />
      </Cell>
      <Cell>
        <Indicator block align="right" size={6} current={5} />
      </Cell>
    </div>
  );
};
export default App;
```

### Do not add 0

```SnackPlayer name=Indicator
import  React from "react";
import { Indicator, Cell } from '@nutui/nutui-react-native';

const App = () => {
  return (
    <Cell>
      <Indicator fillZero={false} size={6} current={5} />
    </Cell>
  );
};
export default App;
```


### Vertical display

```SnackPlayer name=Indicator
import  React from "react";
import { Indicator, Cell } from '@nutui/nutui-react-native';

const App = () => {
  return (
    <Cell>
      <view 
        style={{ height: '100px', width: '50%' }} 
      >
        <Indicator fillZero={false} size={6} current={5} vertical />
      </view>
      <view 
        style={{ height: '100px', width: '50%' }} 
      >
        <Indicator size={6} current={2} vertical />
      </view>
    </Cell>
  );
};
export default App;
```
