generate method
Generates Dart code for an input Dart library.
May create additional outputs through the buildStep
, but the 'primary'
output is Dart code returned through the Future. If there is nothing to
generate for this library may return null, or a Future that resolves to
null or the empty string.
Implementation
@override
FutureOr<String> generate(LibraryReader library, BuildStep buildStep) async {
final values = <String>{};
for (var annotatedElement in library.annotatedWith(typeChecker)) {
final generatedValue = generateForAnnotatedElement(
annotatedElement.element, annotatedElement.annotation, buildStep);
await for (var value in normalizeGeneratorOutput(generatedValue)) {
assert(value.length == value.trim().length);
values.add(value);
}
}
return values.join('\n\n');
}
