0.4.0: Error running FreezedGenerator: ... but freezed has nothing to generate"

[jonasbark]

File:

import 'package:freezed_annotation/freezed_annotation.dart';
part 'second_state.freezed.dart';
part 'second_state.g.dart';

@freezed
abstract class SecondState with _$SecondState {
  const factory SecondState({
    @JsonKey(ignore: true, nullable: true) String dateTime,
    @JsonKey(ignore: true, nullable: true) String uuid,
  }) = _SecondState;

  const factory SecondState.fromJson(Map<String, dynamic> json) => _$SecondStateFromJson(json);
}

Error:

[SEVERE] freezed:freezed on lib/state/second_state/second_state.dart:
Error running FreezedGenerator
Marked SecondState with @freezed, but freezed has nothing to generate

Did I forget something? All other state files fail as well (so it's not the fact that both fields have ignore: true at JsonKey)

That's a regression.

It happens because the constructor is defined on multiple lines. If you format it in a single line, that should work for now.

I'll fix it asap

The fix is released as part of 0.5.0

Thank you for the hard work put into this.

A similar problem is still happening in version 0.10.6 - If you have comments in between the variables, and these comments have parenthesis, you MUST close the parenthesis or freezed won't be able to generate the files:

@freezed
abstract class MyClass with _$MyClass {
  const factory MyClass({
    @required String myStr1,
    @required bool myBool1,

    /// These comments Cause problems only when I (don't close the parenthesis
    // It doesn't matter if you have two or three bar comments, or single quotes, as long as you (close the parenthesis, you'll be fine)
    @required String mySpecialStr,
  }) = _MyClass;

}

So I guess good grammar is always a must :-)
