Reviewer scorecard
“Hot reload, custom rendering engine, and Dart is surprisingly pleasant. Best for custom UI that needs pixel-perfect cross-platform.”
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“Dart limits the developer pool. React Native with TypeScript/JavaScript has a much larger talent market.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“Google's commitment level is uncertain given their track record. React Native has more ecosystem momentum.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
