visitProvideFactory method

@override void visitProvideFactory(int index, TokenElement token, Expression tokenExpression, Reference returnType, Reference function, List<Expression> dependencies, bool isMulti,)

Implement providing token by calling function.

Any dependencies are expected to invoke local methods as appropriate:

refer('inject').call([refer('Dep1')])

Implementation

void visitProvideFactory(
  int index,
  TokenElement token,
  Expression tokenExpression,
  Reference returnType,
  Reference function,

      returnType is TypeReference ? returnType.types : <Reference>[];
  _fieldCache.add(Field((b) => b
    ..name = '_field$index'
    ..type = TypeReference((b) => b
      ..symbol = returnType.symbol
      ..url = returnType.url
      ..types.addAll(types)
      ..isNullable = true)));

  final methodName = '_get${returnType.symbol}\$$index';
  _methodCache.add(
    Method(

        ..name = methodName
        ..returns = returnType
        ..body = refer(fieldName)
            .assignNullAware(function.call(dependencies))
