how can i re-activate the scanner?

[hasgardee]

After one qr scan is done nothing happening, is there any option to re-active scanner again ? if no please add that

I did it this way. Set a parameter key in the declaration of your component like this:

<QRScannerView key={this.state.key} onRead={this.onRead} torchMode={false} hintText="Scan QR code"/>

Then upon scanning the value, increment the key count to another number. This will re-render the component.

onRead = ({data}) => {
    this.setState({
      key: this.state.key + 1
    });
  }
