Getting fatal on iOS emulator

[budde377]

When mounting the widget with

    return MobileScanner(
      key: _qrKey,
      controller: _controller,
      onDetect: (b, a) => widget.onQRViewCreated(b),
    );

I'm getting the fatal error, which crashes the app:

mobile_scanner/SwiftMobileScannerPlugin.swift:177: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

This happens on version 0.1.1.

Do you have any information about the device that you are using?

The error is happening because the camera could not be loaded.
I have made some changes to the plugin. Can you please check using the latest code using this in your pubspec.yaml:

mobile_scanner:
git:

ref: master

@juliansteenbakker
debug on android, when flash is set on torch mode and close the page with navigator pop, the flash still remain
even open the scanner screen again, the flash indicator was off, but the flash still on torch mode

and the screen was blank because
I[/flutter]() ( 7098): MobileScanner: Called start() while already started!

@juliansteenbakker. That makes sense! The emulator doesn't have a camera. The master branch prevents the fatal, thank you for your help!
