generateForAnnotatedElement method

  1. @override
FutureOr<String> generateForAnnotatedElement(
  1. Element element,
  2. ConstantReader annotation,
  3. BuildStep buildStep
)

Implement to return source code to generate for element.

This method is invoked based on finding elements annotated with an instance of T. The annotation is provided as a ConstantReader.

Supported return values include a single String or multiple String instances within an Iterable or Stream. It is also valid to return a Future of String, Iterable, or Stream.

Implementations should return null when no content is generated. Empty or whitespace-only String instances are also ignored.

Implementation

@override
FutureOr<String> generateForAnnotatedElement(Element element, ConstantReader annotation, BuildStep buildStep) async {

  // Extracting Data from all Elements and filling the data into a model to use everywhere
  ExtractedInfoModel dataModel = ExtractedInfoModel(
    element: element,
    source: element.source?.uri.path ?? Strings.unknown,
    type: element.metadata.first.element?.name?.getAnnotationType ?? AnnotationTypes.unknown,
    name: element.name ?? Strings.unknown,
    as: annotation.getAs,
    initialRoute: annotation.getIsInitial,
    unknownRoute: annotation.getIsUnknownRoute,
  );

  // Logging details about founded Annotation
  GeneratorLog.info(title: 'Annotation Found in', data: dataModel.source);
  GeneratorLog.info(title: 'Annotation Name', data: dataModel.name, as: dataModel.as);
  GeneratorLog.info(title: 'Annotation Type', data: dataModel.type);
  GeneratorLog.space();

  // Adding the Element in the main Generator
  CodeGenerator().addElement(dataModel);
  return Strings.empty;
