Sdk: Strange analyzer error : "Invalid constant value" when I use const Text('foo') in Flutter

[rxlabz]

I noticed that when I open a Flutter file containing const Text('foo') , everything works, I can compile and launch the app, but the dart analysis show me a "invalid constant value" .

example gist

if I replace the const Text by a new Text, the error disappears.

I'm using IntelliJ version 2017.1

Do you think this is a dup of one of the other recent issues, @scheglov?

[zoechi]

Looks somewhat similar to #28775

[scheglov]

Open your .analysis_options or analysis_options.yaml file and ensure that there is the following line in it. Also try updating to 1.24 version of SDK.

analyzer:
  language:
    enableAssertInitializer: true

[scheglov]

@kasperl Yes, I think this is a dup of other asserts in initializer issues.

[rxlabz]

I added the analysis.yaml file (I'm not sure if there is not a special way to configure analysis_options for flutter @sethladd ?), restarted the analysis server, but still have the error. My local Dart SDK is updated to 1.24, but I think Flutter is using its own ?

[bwilkerson]

Just to be clear, the name of the analysis options file you added is analysis_options.yaml, correct?

Yes, Flutter bundles a version of the Dart SDK.

[rxlabz]

yes, sorry analysis_options.yaml. not sure if it can help but here are complete project sources : https://github.com/rxlabz/invalid_const_demo

I don't know if it's after upgrading Flutter yesterday, but my "invalid constant value" error seems to be fixed 🤔
