Replacement for the abandoned Android barcode scanner package.

[synga-nl]

Since July 1st the https://github.com/dm77/barcodescanner Android package is abandoned. This means we need to find another package that suits our needs and implement it. This is a thread to share ideas.

The package itself recommends the ML kit from google. Here are some examples: https://github.com/googlesamples/mlkit.

ML Kit requires the Google Play Services. I think it's not a good idea to force the users to use it.
A better option is to create an open interface which also allows to create custom barcode scanners which can be used with this library.
