Compiling lib/main.dart for the Web... 26.0s
Error: Failed to compile application for the Web.

If the title is the actual error message, then this does sound like a bug in dart2js.

[sigmundch]

Thanks for filing the issue!

We need a bit more info to investigate. I believe the stack trace above is an error from the flutter tool when it gets in a bad state after the compilation failed. Could you share with us the stack trace from the dart2js compiler (what comes after "The compiler is broken" which you shared in the title)? Or do you have a small example code that reproduces the crash that we can use to debug?

Thanks!

This is what I get when trying to build to web.

flutter build web --web-renderer html

The compiler is broken.

When compiling the above element, the compiler crashed. It is not
possible to tell if this is caused by a problem in your program or
not. Regardless, the compiler should not crash.

The Dart team would greatly appreciate if you would take a moment to
report this problem at http://dartbug.com/new.

Please include the following information:

• the name and version of your operating system,

• the Dart SDK build number (3.4.0-190.0.dev), and

• the entire message you see here (including the full stack trace

Thanks @bvversoz, unfortunately I think something else in the tooling is hiding the original error.

Is the input you are using by chance something you can reduce to a repro you could share with us so we can try it locally?

@christopherfujino - I'm wondering if flutter tool may be invoking dart2js after a failure on a previous step when generating the app.dill, and that previous error is being shadowed accidentally, is that possible? Are there by chance other issues reported on the flutter issue tracker related to this?

[Chris248539]

I am having the exact same issue, is this something that was resolved?

Target dart2js failed: ProcessException: Process exited abnormally with exit code 253:

The compiler is broken.

Same issue here - This is Breaking all our builds with GitHub Actions which uses ubuntu based runners but on our local mac machines we are able to build without issues.

Assigning to myself to investigate this

Limiting the version of cached_network_image_web in the pubspec.yaml file can avoid this problem

dependency_overrides:
cached_network_image_web: 1.1.1
