Enabling smooth communication between JavaScript and Dart in Flutter
summary
Dart uses the package JS (v0.6.7) and static interop to move JavaScript bindings to compile time, giving type soundness, better performance and WASM compatibility; the talk shows that create.export replaces repeated allowInterop calls and auto‑exports annotated classes for cleaner JS↔Dart calls. Demos include element embedding and a synced counter/animation and a working ChatGPT integration built with a local Node+OpenAI server on :5001 (Express, OpenAI text‑davinci), Flutter web loader tweaks, and the interop flows succeed end‑to‑end.
