I've only worked with flutter and I kinda like it. It's made by Google so I felt like firebase integration would be better on it and maybe better support for Android apps.

I have only made a few simple projects but I feel like they're still very good looking with material 3 material you. I like dart language. I don't think you need to get too used to it to work with if you're already using reactjs or something. It uses stateless and stateful widgets and work like magic. And I think error handling is also done by it not sure though. I'm still a rookie but I'd highly recommend flutter to anyone who wants to start from scratch or coming from somewhere else.
