react-native-circular-progress

React Native component for creating animated, circular progress. Useful for displaying users points for example. Works on iOS & Android.

Example app

Installation

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

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

  1. Link native code for SVG:

react-native link react-native-svg

Usage

Import CircularProgress or AnimatedCircularProgress:

import { AnimatedCircularProgress } from 'react-native-circular-progress';

Use as follows:

<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 style={styles.points}>
        { this.state.fill }
      </Text>
    )
  }
</AnimatedCircularProgress>

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 passing by following props:

  • size – width and height of the circle - could be number or object if you use Aniamted.Value()
  • width - thickness of the lines
  • backgroundWidth - thickness of the background line
  • fill - current, percentage fill (from 0 to 100)
  • prefill - percentage fill before the animation (from 0 to 100)
  • tintColor - color of the progress line
  • backgroundColor - color of the background for the progress line. If unspecified, no background will be rendered
  • rotation - by default, progress starts from the angle = 90⦝, you can change it by setting value from -360 to 360
  • duration - duration of the animation in milliseconds. Default is 500ms
  • easing - animation easing function
  • lineCap - the shape to be used at the ends of the circle. Possible values: butt (default), round or square. (see here)
  • arcSweepAngle - the angle that you want your arc to sweep in the case where you don't want a full circle. Default is 360.
  • children(fill) - you can pass function as a child to receive current fill
  • onAnimationComplete - you can pass a callback function that will be invoked when animation completes. (see here)
