Having been down this road before, I'd recommend Flutter over ReactNative.

ReactNative feels like developing the same app 2.5 times. Once in RN proper, and then covering the same ground for large swaths of the app again for each iOS and Andriod.

Flutter has some pain associated with it (I would highlight the lack of 3rd party and community support compared with RN), but overall I'd say it delivers more on the "write once, run everywhere" promise of RN.

Thanks for the help. I had reached the same conclusion as you from my very brief exploration of the two technologies so far. Flutter seems more self-contained and coherent, at the cost of taking the risk to not integrate well with the native OS (which TBH is the least of my concerns at the moment as long as flutter is able to provide me with something close to iOS 7 feature set support).

What are these large swaths? Other than build stuff we're like 95% shared.
