@fiurthorn does it work if you downgrade to allow only build_web_compilers with this constraint ^1.0.0? It is possible that sdk is to old and doesn't contain the expected files but we put the wrong sdk constraint or something. Possibly your dart sdk got corrupted or something as well and you could try re-installing it.

Alternatively updating your dart sdk should resolve the issue.

Or you could try >=2.0.0 <2.6.1?

Using Dart 2.5.2 shows the a similar result

Sorry, I meant build_web_compilers version >=2.0.0 <2.6.1 (in your pubspec)
