With limited resources you have to choose. If flutter focused on UI elements before Mac OS + Linux stability, the top comment would be "Flutter is a solid option for Windows but without Linux or Mac support it is useless."

The flutter team has proven generally capable of developing UI elements on mobile across iOS/Android. Getting platform stability is a welcome step and i trust them to continue to build out the desktop element set.

Flutter has been my go-to for mobile app dev for years and i haven't considered returning to react native, pure native or cordova since i swapped.

All that being said, i have spent my afternoon debugging an issue with Flutter's first-party camera plugin, so it isn't all roses.
