react-native-circular-progress
React Native component for creating animated, circular progress. Useful for displaying users points for example.
Example app
Installation
Install this component and
react-native-svg:npm i --save react-native-circular-progress react-native-svgLink native code for SVG:
react-native link react-native-svg
Usage
import { AnimatedCircularProgress } from 'react-native-circular-progress';
<AnimatedCircularProgress
size={120}
width={15}
fill={100}
tintColor="#00e0ff"
onAnimationComplete={() => console.log('onAnimationComplete')}
backgroundColor="#3d5875" />You can also define a function that'll receive current progress and for example display it inside the circle:
<AnimatedCircularProgress
size={200}
width={3}
fill={this.state.fill}
tintColor="#00e0ff"
backgroundColor="#3d5875">
{
(fill) => (
<Text>
{ this.state.fill }
</Text>
)
}
</AnimatedCircularProgress>You can also define a function that'll receive the location at the top of the progress circle and render a custom SVG element:
<AnimatedCircularProgress
size={120}
width={15}
fill={100}
tintColor="#00e0ff"
backgroundColor="#3d5875"
padding={10}
renderCap={({ center }) => <Circle cx={center.x} cy={center.y} r="10" fill="blue" />}
/>Finally, you can manually trigger a duration-based timing animation by putting a ref on the component and calling the animate(toValue, duration, easing) function like so:
<AnimatedCircularProgress
ref={(ref) => this.circularProgress = ref}
...
/>this.circularProgress.animate(100, 8000, Easing.quad); // Will fill the progress bar linearly in 8 secondsThe animate-function returns the timing animation so you can chain, run in parallel etc.
Configuration
You can configure the CircularProgress-component by passing the following props:
| Name | Type | Default value | Description |
|---|---|---|---|
| size | number|Animated.Value | required | Width and height of circle |
| width | number | required | Thickness of the progress line |
| backgroundWidth | number | width | Thickness of background circle |
| fill | number (0-100) | 0 | Current progress / fill |
| tintColor | string | black | Color of the progress line |
| tintTransparency | boolean | true | Transparency of the progress line |
| backgroundColor | string | If unspecified, no background line will be rendered | |
| rotation | number (-360 - 360) | 90 | Angle from which the progress starts from |
| lineCap | string | butt | Shape used at ends of progress line. Possible values: butt, round, square |
| arcSweepAngle | number (0-360) | 360 | If you don't want a full circle, specify the arc angle |
| style | ViewPropTypes.style | Extra styling for the main container | |
| children | function | Pass a function as a child. It received the current fill-value as an argument | |
| childrenContainerStyle | ViewPropTypes.style | Extra styling for the children container | |
| padding | number | 0 | Padding applied around the circle to allow for a cap that bleeds outside its boundary |
| dashedBackground | object | { width: 0, gap: 0 } | Bar background as dashed type |
| dashedTint | object | { width: 0, gap: 0 } | Bar tint as dashed type |
| renderCap | function | undefined | Function that's invoked during rendering to draw at the tip of the progress circle |
The following props can further be used on AnimatedCircularProgress:
| Name | Type | Default value | Description |
|---|---|---|---|
| prefill | number (0-100) | 0 | Initial fill-value before animation starts |
| duration | number | 500 | Duration of animation in ms |
| easing | function | Easing.out(Easing.ease) | Animation easing function |
| onAnimationComplete | function | Function that's invoked when the animation completes (both on mount and if called with .animate()) | |
| tintColorSecondary | string | the same as tintColor | To change fill color from tintColor to tintColorSecondary as animation progresses |
AnimatedCircularProgress also exposes the following functions:
| Name | Arguments | Description |
|---|---|---|
| animate | (toVal: number, duration: number, ease: function) | Animate the progress bar to a specific value |
| reAnimate | (prefill: number, toVal: number, duration: number, ease: function) | Re-run animation with a specified prefill-value |
