When was it looked into? The Zulip mobile app was rewritten in Flutter recently, that version was in beta for several months and was finally made the default Zulip app about a month ago. I haven't used Mattermost so can't compare, but the Flutter Zulip is much more responsive and nice than the previous Zulip app.
Our Flutter experience over the last few months since launch has been very positive. Most importantly, development velocity is much faster than it was on React Native.
I liked Zulip a lot until that Flutter rewrite. Maybe it's more accessible now but the new look is not for me. I believe the app navigation is largely unchanged, and still doesn't quite feel right. I love the topic-based model nonetheless.

Rewritten *into* Flutter? People should be rewriting away from Flutter.
https://blog.zulip.com/2025/06/17/flutter-mobile-app-launche... and the previous blog post linked from there gives some context as to why we rewrote the Zulip mobile apps from React Native to Flutter.

To what? What is the alternative?

Mattermost's mobile app is also pretty bad though.
What's poor about it? I've used it for a while and didn't notice anything bad.
It's better these day
