'ConstTopLevelVariableElementImpl' is not a subtype of type 'FieldElement'

[mzakizadeh]

Is this project unmaintained? I do believe that this software won't work with new dart versions...

It's maintained, but only very lightly, as I have time. I'll take a look. The analyzer API probably changed, that's usually what breaks things.

[glesica]

It looks like analyzer 0.4.0 breaks things, but it isn't compatible with the test package so I don't think I can update at this time. However, I'm going to do a dependency override and try to fix the issues I'm seeing so I can push out a fix once the test package is updated.

[glesica]

For reference, here's the stack trace I get when I run DCDG with an override to analyzer 0.4.0...

[glesica]

I've got the exceptions resolved, but the output has changed a bit because of differences in the newer analyzer API so I'm going to fiddle with it to make sure we don't lose any information.

[glesica]

I've updated to the latest analyzer, so the bug described above should no longer exist.
