React Native component for creating animated, circular progress with ReactART. Useful for displaying users points for example. Works on iOS & Android.
Looking for a circular slider? Take a look at my other component – react-native-circular-slider ⏰
- Install library
npm i --save react-native-circular-progress
- 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
Import CircularProgress or AnimatedCircularProgress.
import { AnimatedCircularProgress } from 'react-native-circular-progress';
Use as follows:
<AnimatedCircularProgress
size={120}
width={15}
fill={100}
tintColor="#00e0ff"
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
You can configure the passing by following props:
- size – width and height of the circle
- width - thickness of the 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
- 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)
- arcSweepAngle - the angle that you want your arc to sweep in the case where you don't want a full circle. Default is 360.
- strokeCap -
- capWidth -
- capColor -
- children(fill) - you can pass function as a child to receive current fill
You can find working example in the example
directory of this repository. You can run it by:
git clone https://github.com/bgryszko/react-native-circular-progress.git
cd react-native-circular-progress/example/ProgressChart
npm install
open ios/ProgressChart.xcodeproj
XCode will open. Click Run button and that's it.
Open your emulator and run:
git clone https://github.com/bgryszko/react-native-circular-progress.git
cd react-native-circular-progress/example/ProgressChart
npm install
react-native run-android
