After adding the dependency to my pubspec.yaml and running flutter packages get, I try to run my app and I get this fun error:

 Downloading dependencies

    -> Installing Flutter (1.0.0)

    -> Installing qr_utils (0.1.4)

    [!] Unable to determine Swift version for the following pods:

    - `qr_utils` does not specify a Swift version and none of the targets (`Runner`) integrating it have the
    `SWIFT_VERSION` attribute set. Please contact the author or set the `SWIFT_VERSION` attribute in at least one of the
    targets that integrate this pod.

I've searched around and tried some things out so I figured I'd make an issue and see if anyone knows how to fix. I can get the "specifying target version" error to go away by uncommenting a line in the podfile, but I can't get past the SWIFT_VERSION error.

Open your iOS project in Xcode, add a single Swift file, name it whatever, and Swift will be added to the project. You can now set SWIFT_VERSION. But, the plugin won't run. Depreciated code.
