Functions

findAnnotation<D extends CompilationUnitMember>(CompilationUnit unit, {required String annotationName}) → Annotation?

Returns the first Annotation whose resolved type name matches annotationName on any D declaration in unit, or null if none is found.

findConstructorDeclaration(CompilationUnit unit, String? name) → ConstructorDeclaration?

Returns the first ConstructorDeclaration whose name matches name in unit, or null if none is found. Pass null for name to find the default constructor.

findFactoryConstructorDeclaration(CompilationUnit unit, String? name) → ConstructorDeclaration?

Returns the first factory ConstructorDeclaration whose name matches name in unit, or null if none is found. Pass null for name to find the default factory constructor.

findImportDirective(CompilationUnit unit) → ImportDirective?

Returns the first ImportDirective, or null if none is found.

findMethodDeclaration(CompilationUnit unit, String name) → MethodDeclaration?

Returns the first MethodDeclaration whose name matches name, or null if none is found.

getAnnotation<D extends CompilationUnitMember>(CompilationUnit unit, {required String annotationName}) → Annotation

Returns the first Annotation whose resolved type name matches annotationName on any D declaration in unit, failing the test if absent.

getConstructorDeclaration(CompilationUnit unit, String? name) → ConstructorDeclaration

Returns the first ConstructorDeclaration whose name matches name in unit, failing the test if absent. Pass null for name to find the default constructor.

getFactoryConstructorDeclaration(CompilationUnit unit, String? name) → ConstructorDeclaration

Returns the first factory ConstructorDeclaration whose name matches name in unit, failing the test if absent. Pass null for name to find the default factory constructor.

getImportDirective(CompilationUnit unit) → ImportDirective

Returns the first ImportDirective, failing the test if absent.

getMethodDeclaration(CompilationUnit unit, String name) → MethodDeclaration

Returns the first MethodDeclaration whose name matches name, failing the test if absent.
