We did use flutter to build something like a companion app for our B2B product targeted at enterprises. One dev supported Android and iOS and performance was good (no battery issues, etc for an app that was mostly always running). It was a blessing that we chose a cross platform approach as our users did not decide which the devices they use, corporate does. And it can change its mind. I do get the fear of the Google dependency, though. I did feel lucky that support did not end before we were done with it.
