Improve/rename `start` property

Well, this property is a little confusing, my suggestion is to rename it to autostart and refactor the code to make less use of it. Also, methods should be included to start/stop scan and play/pause the preview.

If people still wants this property, I thikn it should be at least renamed to make it clear what it does. Also, there are implementations of the component property that reproduces strange behaviors.

Thanks! Well… there’s no ETA but we wanna release as soon as possible. At this point you can’t pause scanning directly you can only stop and start it, but when you stop it the preview is gone. A workaround would be that when you pause scanning you just don’t handle the scan-result. This is just a workaround since decoding takes place and generates CPU-load but oh well… 😉

Pseudo code:

<ngx-zxing [start]="cameraStarted" [device]="selectedDevice" (onCamsFound)="displayCameras($event)" (onScan)="handleQrCodeResult($event)"></ngx-zxing>

handleQrCodeResult(result: string): void {
  if(!this.paused) {
    console.log("My result is", result);
  }
}

Awesome work guys! When would the v1.0.0 be released ? Is there a way to pause the scanning and resume scanning when needed ?
