React Native component for creating animated, circular progress with ReactART

react-native-circular-progress

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

Example app

Installation

1. Install library npm i --save react-native-circular-progress-patch
2. As Expo user you are good to go right now, or alternatively install ART:
3. Link ART library to your ReactNative project (how to link a library?). You'll find ReactART library in node_modules/react-native/Libraries/ART/ART.xcodeproj

Usage

Import CircularProgress or AnimatedCircularProgress.

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

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 performLinearAnimation(toValue, duration) function like so:

<AnimatedCircularProgress
  ref='circularProgress'
  ...
/>

this.refs.circularProgress.performLinearAnimation(100, 8000); // Will fill the progress bar linearly in 8 seconds

Configuration

You can configure the passing by following props:

• size – width and height of the circle
• 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 a progress line
• backgroundColor - color of a background for progress line. Use 'transparent' to hide
• rotation - by default, progress starts from the angle = 90⦝, you can change it by setting value from -360 to 360
• tension - the tension value for the spring animation (see here)
• friction - the friction value for the spring animation (see here)
• linecap - the shape to be used at the ends of the circle. Possible values: butt (default), round or square. (see here)
• 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 is complete. (see here)
• onLinearAnimationComplete - you can pass a callback function that will be invoked when linear animation is complete. (see here)
