Opening a new pr following #46 with the feature as an opt-in option, updated examples, and for the wiki the only relevant change seems to be this:

This fork is starting to deviate a bit from the initial PR so I think I'll just keep it as a fork at least until it's more polished.

@guillaumeboehm we would be super happy to have this merged

I don't mind reopening but I doubt that the maintainer is expecting to extend the project more. I also stopped Flutter development a little while ago and I don't think I'll go back to it any time soon, so I won't update the code if needed. Maybe you could finalize this PR using my code, but you might end up having to fork and maintain this whole project yourself if you want more features.

I will close this pull request as I`m currently creating a new version with an updated API which will include this functionality as well.
