Same issue here, did you solve it? (Seems that people in the link does not?)

[Aoi-hosizora]

@fzyzcjy Just flutter clean and flutter packages get, and rerun flutter run.

See the related issue https://github.com/dart-lang/package_config/issues/85.

If you manually delete your .dart_tool/build directory that should work I think.
