+- class definitions - Captures standard class definitions
+- method signatures - Captures all method types (getters, setters, constructors, factory, operators)
+- function signatures - Captures standalone function definitions
+- mixin declarations - Captures Dart mixin definitions
+- extension declarations - Captures extension methods on existing types
+- enum declarations - Captures enum definitions
+- type aliases - Captures typedef declarations
+- references - Captures class instantiation, method calls, property access
