Flutter Web compiles Google's cross-platform Flutter framework (normally used for iOS/Android apps) down to a browser-renderable target, letting teams ship the same Dart codebase to web, mobile, and desktop. It produces one of the most unmistakable fingerprints in this database: rather than ordinary HTML, Flutter Web renders into a `<flt-glass-pane>` custom element bootstrapped by `flutter.js` — a rendering approach unique enough that AIWebsiteDetector treats it as a near-certain, high-confidence signal whenever present.
