Flutter still has its quirks, but hands down, it's the best platform for the majority of "standard" apps. Great developer experience, acceptable performance and size.
Also, about hiring.. from my experience, it's one of my selling points in recruiting mobile developers. Many mobile developers want to learn Flutter, so I easily get dozens of candidates who know Flutter only from their hobby projects but want to get involved in real projects. But, of course, you still need some senior Flutter guy.
My only complaint is since the platform is expanding, things break too easily. You _can_ lock dependencies, but you'll feel guilty.
