React Native QR Code Scanner

A highly customizable QR Code scanner based on react-native-qrcode-scanner-view.

What I Changed ?

I had this issue and I didn't get any solution on this page. There is problem with scanBarStyle and somebody has recommended remove scanBarStyle property. I changed this property in original QR Scanner file instead of removing. Also there is problem with componentDidMount() and componentWillUnmount() functions. I fixed this problem with the following codes.

listener; componentDidMount() { listener = AppState.addEventListener("change", this.handleAppStateChange); } componentWillUnmount() { listener.remove();
this.rnCamera && this.rnCamera.pausePreview(); }
