declaredFragment property
The fragment declared by this declaration.
Returns null if the AST structure hasn't been resolved.
Returns null for FieldDeclaration and TopLevelVariableDeclaration
because these nodes don't declare any fragments, but individual
VariableDeclarations inside them do. They are Declarations mostly to
fit into ClassDeclaration.members and CompilationUnit.declarations.
Implementation
@override
ClassFragment? get declaredFragment;
