flutter pub run build_runner build --verbose and post the logs to a new issue?
Since the analysis error happens in the SDK, this might be https://github.com/flutter/flutter/issues/62240#issuecomment-668997665 (see comment for workaround). If that doesn't work, can you re-run the build with
flutter pub run build_runner build --verboseand post the logs to a new issue?
is not working

@natebosch Thanks to your blog about the new build system: https://lessworsemorebetter.com/2018/04/17/dart-builds-how-did-we-get-here.html.
We're exploring auto-generated log into AngularDar or Flutter Web framework method, something like https://medium.com/flutter/building-performant-flutter-widgets-3b2558aa08fa
Is it possible to use source_gen?
buildStep.read*, but what's so special about them? I'm trying to setup a multi-package build where a non-root package has build steps reading files outside of lib/ (but in the same package), and was surprised about this behavior.

[!] The "version" command is deprecated and will be removed in a future version of Flutter.
1.20.3
String.fromEnvironment('SOME_VAR') should work.
I did find that this was underdocumented so I added a section on it to the README:
This also describes how to define these on the command line - it's an unfortunately long argument.
Note that parsing for booleans is broken in the current versions so it's better for now to always uses strings - 'true' instead of true for bools. Same for ints - '1'. In future versions this shouldn't be necessary.
Hi, I'm using json_annotation with json_serializable to validate json responses, and I'm wondering why isn't there a way to validate the types, and catch an exception if some type is invalid, so far these are the exceptions I catch:
} on FormatException catch (e) {
// it's not a valid json
} on MissingRequiredKeysException catch (e) {
// a required key is missing
} on DisallowedNullValueException {
// a required key is null
}I'd like to also catch an exception for when a type is mismatching the expectation. For example I'm expecting {"seen" : true} but I'm getting {"seen": "hello"}, is there a way to use json_annotation to catch this error? If not, why? is this not a very important thing and can be done otherwise?
checked build option, those exceptions would be wrapped in a CheckedFromJsonException.
@alanknight-wk I would expect the dart command to still support -D defines to run things but I'm not sure which subcommands would support or need it. Is it dart compile that you are trying to use? I don't think that defines would be meaningful other than in compile or run.
We don't have full support for running dartdevc.dart. I'm not sure specifically what you are looking to do with that command but I do know that it doesn't currently read language versions from package_config.json by itself.
