NestMapping constructor
NestMapping(
- MethodElement method,
- VariableElement input
Implementation
NestMapping(this.method, this.input) {
methodReturnNullable = method.returnType.nullabilitySuffix == NullabilitySuffix.question;
inputNullable = input.type.nullabilitySuffix == NullabilitySuffix.question;
methodParamterNullable = method.parameters.first.type.nullabilitySuffix == NullabilitySuffix.question;
returnNullable =
(inputNullable && !methodParamterNullable) || // 'a == null ? null : call(a)'. So the output is nullable.
(inputNullable && methodReturnNullable); // if input is not null, the method return is not
