They both are just fine. I hear people just go with which one they have the most experience in. Since I am starting from scratch, I'm trying Quasar/Vue. Since Flutter is Google's baby and React is kinda like Facebook's baby, I feel more independent with Quasar/Vue. If you made me choose between the Flutter or React native, I might choose flutter and try flutterflow(nocode).
I like .app too. I think of a web app when I see it. Did anyone mention .co? That seems really close to .com and it's even shorter and seems pretty legit. Any more details on the project? maybe we can help come up with a cool name? good luck!
