Silent failure when no Camera Usage Description in info.plist.

[ghost]

Create a new flutter project using example as main.dart. Getting only black screen on iPhone7.

However, running example in your plug-in project works. I'm assuming it's an invalid programmer at keyboard error, but is there additional set up I need to do? Any clues?

Using pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  qr_mobile_vision: ^0.1.0

That should be enough to get it going, so I'm not really sure what's going on. You've copied https://github.com/rmtmckenzie/flutter_qr_mobile_vision/blob/master/example/lib/main.dart exactly, and run flutter packages get?

The only other things I can think of are running pod install in the ios folder, or opening the xcode project and running from there.

I just realized what the problem is. You need to set a particular string in the ios/Runner/info.plist stating what you're going to use the camera for, otherwise iOS fails pretty much silently when you try to use the camera API. It should have been returning some sort of platform exception, although when I tried it it didn't the first time. If I tried opening and closing the camera a few times it started showing the exception then.

Either open the Info.plist in xcode and add the Privacy - Camera Usage Description key with something like 'Scan QR Codes' or

<key>NSCameraUsageDescriptoin</key>
<string>Scan QR Codes.</string>

to the Info.plist directly using whichever editor.

I'm going to leave this issue open as a TODO for myself (and I've changed the title). I need to at least document this in the README for this repo, or return a better error (or possibly even check the info.plist myself and fail earlier).

Very excellent. I'll do that.
