Analysis server doesn't run macros correctly when they're provided through an "export"

[rrousselGit]

Hello!

It appears that using export 'macro.dart' breaks the "Go to augmentation" codelenses.

You could define any macro:

// macro.dart
macro class Example {
...
}

Then re-export it in a different file:

// foo.dart
export 'macro.dart';

And finally import the macro through the export:

import 'foo.dart';

@Example()
// No "Go to augmentation" shows up here
class MyClass {}

@rrousselGit are you sure the macro is running? While I can reproduce the CodeLens not appearing, it also seems like the macro is not running (because here, "hello" becomes an error):

m.mp4

The behaviour I'm seeing doesn't seem like just a CodeLens issue, but I don't know if it's the same as what you're seeing.

This is more than a codelense issue yes.

But if you run the code, it works:

You can dart --enable-experiment macros lib/foo.dart just fine. So the error is purely on the analyzer side

Ah, gotcha. I've updated the title then - seems to be something wrong with the analysis server running the macro and not as I first suspected with the generation of LSP CodeLenses.

I can reproduce it.
