Camera not working when re-mounted

[ishita-kothari]

Hello,

I am unable to run camera when the screen is once removed from the stack in navigation and then re mounted. I am using rnrf for navigation. The code is shown below:

_onBarCodeRead(result) {
var $this = this;
if (this.state.barCodeFlag) {
this.setState({barCodeFlag: false})
Actions.pop();
Actions.result({id: result.data})
}
}

This is the way I am changing my routes. When I come back to QR code page, I am unable to run camera. It shows me white screen with green box.

Please help me solve this issue.

Thanks!
