import RNQRGenerator from 'rn-qr-generator';
import CameraRoll from "@react-native-community/cameraroll";
 
RNQRGenerator.generate({
  value: 'your_qr_string_value_here',
  height: 100,              // height of the output image
  width: 100,               // width of the output image
  base64: false,            // default 'false'
  backgroundColor: 'black', // default 'white'
  color: 'white',           // default 'black'
})
  .then(response => {
    const { uri, width, height, base64 } = response;
    this.setState({ imageUri: uri });
    CameraRoll.save(uri);
    
  })
  .catch(error => console.log('Cannot create QR code', error));
