Error in generating files build runner for version 4.0.0-nullsafety.0

[mammba01012018]

Getting error with running "flutter pub run build_runner build --delete-conflicting-outputs".

Here's my definition in service

@post(path: "/api/updateMember")
Future<Response> updateMember(@Body() Member body);

and I'm getting this error

It used to work on previous build (version 3.0.6). Any idea on why this does not work now

Same issue for me

[deepak-ra]

Any Solution?

[lejard-h]

Any chance someone provide enough code to repro ?

Also which version of flutter/dart sdk are you using ?

[deepak-ra]

@lejard-h
Dart SDK version: 2.12.2
Flutter 2.0.3

chopper: ^4.0.0-nullsafety.0
build_runner: ^1.12.2
chopper_generator: ^4.0.0-nullsafety.0

Code:
@Post(path: '/client/profile/add/address') Future<Response> addAddress(@Body() Map<String, dynamic> data);

Error:
line 75, column 61 of .: Expected to find ')'.
@override Future<Response<dynamic>> addAddress(Map<String*, dynamic>* data) { final $url = '/client/profile/add/address';

Any Update on this By chance?
Not able to work further on my app, as this is the breaking/{something} stuff.

[BirjuVachhani]

Same here.

[saisasanksunkavalli]

Was facing the same issue here. Any update on this ?

Dependencies included

chopper_generator: ^4.0.0-nullsafety.0
chopper: ^4.0.0-nullsafety.0

[IanWorthington]

Same. 3.0.6 parses it ok.

[SEVERE] chopper_generator:chopper_generator on lib/YahooService.dart:

Could not format because the source could not be parsed:

Sorry I still can't reproduce.

Maybe double check all your packages are up to date. Probably an issue with the analyzer.

@JEuler @stewemetal any ideas ?

[BirjuVachhani]

@lejard-h IF it comes to overriding analyzer dependency, which version should we use?

[lejard-h]

do you infos when running dart pub outdated ?

I ran my tests with NO outdated dependencies (except graphs) with Flutter 2.0.3 and dart sdk 2.12.2

[deepak-kumar-swain]

Got the solution:

change sdk to sdk: ">=2.12.0 <3.0.0"
add chopper: ^4.0.0-nullsafety.0 in dependencies and
chopper_generator: ^4.0.0-nullsafety.0
build_runner: ^1.5.0 in dev_dependencies

[BirjuVachhani]

@lejard-h
This is what I'm getting when running pub outdated command.

As my project is not migrated to null-safety completely as 2-3 dependencies are yet to be migrated and then I'd have to migrate my project, I am still using Dart >=2.7.0 constraint.

same issue for me

[JEuler]

Sorry, was out on vacation. I'm getting this error on my paused work project. So, I will investigate it and try to solve it on weekend. 👍

[JEuler]

Oh, lol. I forgot to change environment to this:
sdk: ">=2.12.0 <3.0.0"
Now it is working :)

@bbader000 @BirjuVachhani @IanWorthington @saisasanksunkavalli @deepak-ra @mammba01012018 @christosoikonomou

[JEuler]

Guys? :) Do you have it working? :)

[BirjuVachhani]

@JEuler Not yet. The targeting dart SDK to 2.12.0 works but I cannot use it right now as all the dependencies are not migrated to null safety and I can't migrate my project completely.

[JEuler]

But this is not related to the chopper, I believe )

[BirjuVachhani]

@JEuler chopper generator is not able to generate code in this case. It fails with exit code 1.

[JEuler]

But it is a null-safety version of chopper_generator. So, it depends on the null-safety version of build_runner and other libs and the 2.12.0 is needed. вт, 20 апр. 2021 г. в 07:43, Birju Vachhani ***@***.***>:

[BirjuVachhani]

@JEuler Yes, I agree. When I tried this, I satisfied the dependency graph for the project and there were no dependency overrides. The only thing remaining was to target SDK 2.12.0 and migrate my own source code. Now I think I will have to wait until all the dependencies are null-safe and then start migrating.

[JEuler]

Okay, I will close that issue. Everyone, feel free to reopen it, but:

it is a null-safety version of chopper_generator. So, it depends on the
null-safety version of build_runner and other libs and the 2.12.0 SDK is
needed.

[BirjuVachhani]

@JEuler build_runner doesn't have a null safe version. Besides pub upgrade and pug get commands execute successfully without any errors so all the dependencies must be satisfied. I feel like this is not causing issue but it must be something else. Maybe it is because of SDK 2.12.0 and some internal dart code

[JEuler]

I haven't checked the build_runner version, so, I'm wrong, but I mean that this is version with fresh dependencies and it depends on 2.12.0 SDK, so, generator is working with fresh SDK :)
