generateForAnnotatedElement method

  1. @override
dynamic generateForAnnotatedElement (
  1. Element element,
  2. ConstantReader annotation,
  3. BuildStep buildStep
)
override

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
dynamic generateForAnnotatedElement(
    Element element, ConstantReader annotation, BuildStep buildStep) {
  String source = element.metadata[0].toSource();
  String sh = element.source.shortName, ex = buildStep.inputId.extension;

  var annotation = element.metadata.first.constantValue;

  generatedScreens.putIfAbsent(
      source.substring(source.indexOf("'") + 1, source.lastIndexOf("'")),
      () => {
            #uri: element.source.uri.toString(),
            #className: "${underscoreToCambel(sh.replaceAll(ex, ''))}()",
            #initial: annotation.getField('isInitial')?.toBoolValue()
          });
  writeMap();
