Ask HN: Choosing a multi platform dev framework for a side project?

Looking to do:

- Big 3 desktop (Mac, Win, Lin)

- Big 2 mobile (iOS/iPadOS/TV/Watch and Android/TV)

- Web

Choices so far from most to least usable:

- Avalonia UI (+perf +platforms ~C#)

- react-native (-perf +react)

- Flutter (~dart +shipped)

- Feathers UI (~haxe -tiny community)

- .Net MAUI (-perf -Linux) -> Avalonia instead (Reactive is similar to React in principle)
