Get empty after scan in windows #12

Hi! Thank you for create this plugin. I got an empty string after scan barcode. Is there any way to solve this problem?

It seems that in some cases Windows uses RawKeyDownEvent instead of the implementation's RawKeyUpEvent. I've created a PR, #14 , in which it is possible to set the use of RawKeyDownEvent by setting the useKeyDownEvent to true. Keep in mind that using this on non-Windows systems might result in issues. A possible way to overcome this would be to use Platform.isWindows if you are supporting multiple operating systems.

Would you be able to see if the PR I created works as intended? You can test this by changing the dependency in pubspec.yaml to:

  flutter_barcode_listener:
    git:
      url: https://github.com/danielroek/flutter_barcode_listener.git
      ref: feature/key_down_event

Hi! Want to thank you for your package! I also got this problem in windows and i've tried to use your dependency from git, but they also did not work. So i took your package and replaced method and used it localy. This way that worked!

Hey @tosyak ,

Could you provide the method you changed to make it work? That way we'd be able to improve this package.
