For the emptyStar, fullStar, halfStar, and iconSet props, please refer to the react-native-vector-icons package for the valid string names for the star icons. When selecting the icon string names, you must remember to remove the font family name before the first hyphen. For example, if you want to use the ion-ios-star from the Ionicon font set, you would set the fullStar prop to ios-star and the iconSet to Ionicons.

For the animation prop, please refer to the react-native-animatable package for valid string names for the different animations available.

General Star Example

The following example will render 3.5 stars out of 5 stars using the star-o for the empty star icon, star-half-o for the half star icon, and star for the full star icon from the FontAwesome icon set in black color.

import StarRating from 'react-native-star-rating';

class GeneralStarExample extends Component {

  constructor(props) {
    super(props);
    this.state = {
      starCount: 3.5
    };
  }

  onStarRatingPress(rating) {
    this.setState({
      starCount: rating
    });
  }

  render() {
    return (
      <StarRating
        disabled={false}
        maxStars={5}
        rating={this.state.starCount}
        selectedStar={(rating) => this.onStarRatingPress(rating)}
      />
    );
  }
}

export default GeneralStarExample

Custom Star Case

The following example will render 2.5 stars out of 7 stars using the ios-star-outline for the empty star icon, ios-star-half for the half star icon, and ios-star for the full star icon from the Ionicons icon set in red color.

import StarRating from 'react-native-star-rating';

class CustomStarExample extends Component {

  constructor(props) {
    super(props);
    this.state = {
      starCount: 2.5
    };
  }

  onStarRatingPress(rating) {
    this.setState({
      starCount: rating
    });
  }

  render() {
    return (
      <StarRating
        disabled={false}
        emptyStar={'ios-star-outline'}
        fullStar={'ios-star'}
        halfStar={'ios-star-half'}
        iconSet={'Ionicons'}
        maxStars={7}
        rating={this.state.starCount}
        selectedStar={(rating) => this.onStarRatingPress(rating)}
        fullStarColor={'red'}
      />
    );
  }
