+// NOTE:
+// This file previously declared IconDataBrands / IconDataSolid / IconDataRegular
+// / IconDataLight / IconDataThin / IconDataDuotone as subclasses of [IconData].
+// Newer Flutter SDKs mark [IconData] as a `final class`, which can no longer be
+// extended outside its own library, so those subclasses no longer compile.
+//
+// The generated icon constants in `font_awesome_flutter.dart` now construct
+// plain `const IconData(..., fontFamily: '<FontAwesome...>', fontPackage:
+// 'font_awesome_flutter')` directly, so these helper subclasses are no longer
+// needed. Using const [IconData] literals also keeps icon tree-shaking working.
