Build: Bad state: Unexpected diagnostics: This requires the 'non-nullable' language feature to be enabled.
Dart VM version: 2.7.0 (Fri Dec 6 16:26:51 2019 +0100) on "windows_x64"
build_runner: ^1.10.0
Flutter: 1.19.0-2.0.pre.83
Android 8 (adroid-x86)
I'm using build_runner to generate json and retrofit code. I used this feature on my old project with build_runner: ^1.7.3 and it had no error. But today I create a new project and it build failed:
Bad state: Unexpected diagnostics:
E:\Android\flutter\bin\cache\dart-sdk\lib\internal\internal.dart:172:16 - This requires the 'non-nullable' language feature to be enabled.
I have tried to use 1.7.3 but it also failed. This really puzzled me.
Here is my new project's logs with error:

Can you run with --verbose so we can see the full stack trace? Also, can you let us know what version of build_resolvers package you have?
@jakemac53 - I assume this has something to do with the way we configure the analyzer. Have you seen anything similar?

@natebosch I don't use build_resolvers package. Should I add this to dev_dependencies?
dev_dependencies:
flutter_test:
sdk: flutter
flutter_localizations:
sdk: flutter
build_runner: ^1.10.0
build_resolvers: ^1.3.9
json_serializable: ^3.3.0
retrofit_generator: ^1.3.4+2
The following logs is generated when I delete all the .dart in lib/ and preserve a test.dart in test/.

Ya this is failing when summarizing the SDK. It sounds like you need to update build_resolvers - this is a transitive dependency of build_runner so you do not need to add it explicitly but you do need to run flutter packages pub upgrade to get the latest version.
You can see what your current version is in the output of that command, or by looking at your pubspec.lock.

The version you will need is at least 1.3.8
jakemac53
on 18 Jun 2020
I don't use
build_resolverspackage. Should I add this to dev_dependencies?
Should not need to, as Jake mentions it's already a transitive dependency. Just need to upgrade to the latest to verify. If you are already on the latest you can get, let us know what version you have. You can see the current version with flutter packages deps | grep build_resolvers

@jakemac53 The latest version is 1.3.9. I used the flutter packages deps by @natebosch and it shows the version of build_resolvers is 1.3.9. (My last project is also 1.3.9)
Well now it also failes to run build_runner build.
$ flutter packages deps | grep build_resolvers
| |-- build_resolvers 1.3.9
| | |-- build_resolvers...
I have also upgraded the packages and here is the related logs(maybe):
$ flutter packages pub upgrade
Resolving dependencies...
_fe_analyzer_shared 4.0.0

json_serializable 3.3.0
retrofit 1.3.4
> retrofit_generator 1.3.7+2 (was 1.3.7)
One other possibility, I know that there at least used to be one really weird edge case where flutter packages and flutter pub would actually refer to completely different pub caches (long story).
If you do flutter pub deps | grep build_resolvers what do you see? You can also try flutter packages pub run build_runner build --verbose.

@jakemac53 Oh, I just realize that vsc is using flutter packages get rather than flutter pub get, but it calls flutter pub get?
(Although I have copied my previous project to new one, and updated lib/ and pubspec.yaml. It successed normally.)
Here is logs after flutter pub deps | grep build_resolvers and flutter packages deps | grep build_resolvers:
$ flutter pub deps | grep build_resolvers
| |-- build_resolvers 1.3.9
| | |-- build_resolvers...
$ flutter packages deps | grep build_resolvers

Hmmm... maybe I think this problem is invoked by some dependencies?
I created another flutter project and copied the pubspec.lock and pubspec.yaml, this won't generate any exception.
Here is the demo fles: https://gist.github.com/Aoi-hosizora/721a63c68dc5e761d53fe1e364e9ca0d.
So I just close this issue.

Well, I find that it works after I upgrade to Flutter 1.20.0-3.0.pre.142 and Dart 2.7.0!!
flutter clean
flutter packages pub upgrade
flutter pub run build_runner build
build_runner: ^1.7.3
json_serializable: ^3.3.0
retrofit_generator: ^1.3.4+2
build_resolvers:
dependency: transitive
description:
name: build_resolvers
url: "https://pub.flutter-io.cn"
source: hosted
version: "1.3.10"
This works for me: https://github.com/flutter/flutter/issues/62240#issuecomment-663978057 !!!
