For ios and android maybe but I doubt for web. Also 12k+ open issues, team layoffs and all founders that left don't brink confidence to flutter. I think also roadmap and progress in last year doesn't look stellar.
On the other hand I think flutter lost a lot of benefits comparing to 5 years ago - now we have stable better swift and swiftui and better kotlin with jetpack compose - those support also apple watch, macos, tvos, visions os, Google wear, Google TV and with current jetbrains compose desktops like windows is already stable.
React native and web ecosystem also improved a lot in the last year.
I did checked pulse for those on github on regular bases. Change to monthly and notice out of 450commits more than 170 commits are by flutter-engine-autoroll bot just auto updating some packages, then next second user did ~30commits, then you have few another flutter bots with some commits. Then go compare with react native.
You are cherry picking things here. If this is some ideological thing for you I’m really not interested in having that conversation.
The health of the two projects genuinely isn’t close at all. Comparing what they are actually both shipping in terms of features in the last year is two very very different stories.
I'm neither flutter nor react native developer just native mobile dev but evaluating both techs so don't have stake in the game right now. Just showing to other so they can make their own judgement:
The first and the third paragraphs really haven’t been true for some time now.
Flutter is absolutely production ready as a cross platform GUI.
