three_dart Fundamentals

Iron Law

Always call renderer.dispose() in the widget dispose() method — failing to do so leaks the WebGL context, causing a crash after ~8 widget recreations on mobile.

Flutter uses the three_dart package — a Dart port of Three.js. API concepts are identical to Three.js; only syntax changes (Dart instead of JavaScript).
