The interesting part of Flutter for me is that it powers Fuchsia.
IF Fuchsia becomes a major thing, like the future of Android (and I can't emphasise enough how much it is uncertain right now) then it might become very interesting as a way to publish your new app on Fuchsia while being able to publish it on Android as well in order to support `legacy` devices (again, supposing that Android is abandoned in favor of Fuchsia)
Otherwise, it is 'just' another hybrid solution with the usual caveats.
