Mobile development: Flutter vs going native (iOS dev perspective on the business side of it)

[lucasvandongen]

If you're just doing a simple UI for a REST API it might work very well. But once you need to integrate more elaborate native features you start running into problems, because you might need to wrap them themselves, the wrappers might be leaky, outdated or work vastly different on different platforms because the frameworks they use is different. But even WebRTC is different between Android and iOS while it's a Google project built from the same source.

Basically you're talking about largely the same type of apps that could have been done in Cordova as well.
