@override void writeFlutterApi(ObjcOptions generatorOptions, Root root, Indent indent, Api api, { required String dartPackageName, })

Writes a single Flutter Api to indent.

Implementation

@override

  ObjcOptions generatorOptions,
  Root root,
  Indent indent,
  Api api, {
  required String dartPackageName,
}) {

  indent.newln();
  final String apiName = _className(generatorOptions.prefix, api.name);

  indent.writeln('@interface $apiName : NSObject');

      generatorOptions.prefix, func.returnType,
      // Nullability is required since the return must be nil if NSError is set.
      forceNullability: true,
    );
    final String callbackType =
        _callbackForType(func.returnType, returnType, generatorOptions);
    addDocumentationComments(
