react-native-circular-progress

React Native component for creating animated, circular progress. Useful for displaying users points for example.

Example app

Installation

1. Install this component and react-native-svg:

   npm i --save react-native-circular-progress react-native-svg

2. Link 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 seconds

The 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 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 receiveds 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 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
