I have working to replicate TanStack query experience by writing my own queries wrapped around PowerSync, although actually on Flutter (using Flutter Hooks! which was cool to use coming from React). It’s a very internal design meant for my app tetr[1] right now (and actually being migrated over from Realm). I am hoping to potentially standardize it and publish a package once it’s mature enough but not too wrap to make your own hooks around them for your needs.
