React Native Rating Bar

A React Native component for generating and displaying interactive Tap or Swipe enabled Ratings supporting custom icons from vector icons and images.

🚀 Installation

Install the package using yarn or npm:

yarn add @aashu-dubey/react-native-rating-bar

Or

npm install --save @aashu-dubey/react-native-rating-bar

And you also need to install react-native-gesture-handler, as we're using it for Swipe/Tap gestures:

yarn add react-native-gesture-handler

then wrap your App's entry point with GestureHandlerRootView (see official doc) in order for drag to rate feature to work

export default function App() {
  return (
    <GestureHandlerRootView style={{ flex: 1 }}>
      {/* content */}
    </GestureHandlerRootView>
  );
}

For more info see gesture-handler's official Installation guide

📲 Examples

Using RatingBar Component

There are few different ways to use Rating Bar component

Using ratingElement prop:

<RatingBar
  initialRating={3.5}
  direction="horizontal"
  allowHalfRating
  itemCount={5}
  itemPadding={4}
  ratingElement={{
    full: (
      <Image
        style={{ width: 30, height: 30, tintColor: '#54D3C2' }}
        resizeMode="contain"
        source={require('./assets/heart.png')}
      />
    ),
    half: (
      <Image
        style={{ width: 30, height: 30, tintColor: '#54D3C2' }}
        resizeMode="contain"
        source={require('./assets/heart_half.png')}
      />
    ),
    empty: (
      <Image
        style={{ width: 30, height: 30, tintColor: '#54D3C2' }}
        resizeMode="contain"
        source={require('./assets/heart_border.png')}
      />
    ),
  }}
  onRatingUpdate={value => console.log(value)}
/>

Assets are available here.
Or you can use Icon component from react-native-vector-icons:

<RatingBar
  initialRating={3.5}
  direction="horizontal"
  allowHalfRating
  itemCount={5}
  itemPadding={4}
  ratingElement={{
    full: <Icon name="star-rate" color="#54D3C2" size={40} />,
    half: <Icon name="star-half" color="#54D3C2" size={40} />,
    empty: <Icon name="star-border" color="#54D3C2" size={40} />,
  }}
  onRatingUpdate={value => console.log(value)}
/>

Using itemBuilder prop:

<RatingBar
  initialRating={2.5}
  minRating={1}
  direction="horizontal"
  allowHalfRating
  unratedColor="rgba(255, 193, 7, 0.2)"
  itemCount={5}
  itemPadding={4}
  itemSize={40}
  itemBuilder={() => <Icon name="star" color="#FFC107" size={40} />}
  onRatingUpdate={value => console.log(value)}
/>

Based on itemBuilder prop's index param:

Passing different component in itemBuilder based on index param value:

<RatingBar
  initialRating={3}
  itemCount={5}
  itemPadding={4}
  itemBuilder={index => {
    switch (index) {
      case 0:
        return (
          <Icon name="sentiment-very-dissatisfied" color="#F44336" size={40} />
        );
      case 1:
        return <Icon name="sentiment-dissatisfied" color="#FF5252" size={40} />;
      case 2:
        return <Icon name="sentiment-neutral" color="#FFC107" size={40} />;
      case 3:
        return <Icon name="sentiment-satisfied" color="#8BC34A" size={40} />;
      case 4:
        return (
          <Icon name="sentiment-very-satisfied" color="#4CAF50" size={40} />
        );
      default:
        return <View />;
    }
  }}
  onRatingUpdate={value => console.log(value)}
/>

Using RatingBarIndicator Component

<RatingBarIndicator
  rating={3.37}
  itemBuilder={() => <Icon name="star" color="#FFC107" />}
  itemCount={5}
  itemSize={50}
  unratedColor="rgba(255, 193, 7, 0.2)"
  direction="horizontal" // Or "vertical", "vertical-reverse"
/>

Vertical Mode

vertical	vertical-reverse

🚧 Issue

You may notice, especially in Android drag to rate is a little slower, this is a dev only problem, if you run your build on release mode or even debug with JS dev mode disabled it will run way way faster, something related to this. That being said, I'm trying to fix this.

🌻 Motivation

This project was initially started as I needed to implement a rating component for Hotel Booking UI template in my other open source project for learning React-Native-UI-Templates, and failing to find a proper solution that works same as the original Project in Flutter, I decided to replicate the Rating library used in the Flutter project.
So this package is initially inspired from Flutter package flutter_rating_bar (including the demo 😅) with some extra added functionalities.
