homebrew-dart: brew update throws " couldn't find remote ref refs/heads/master"

this happens since flutter forward

➜  ~ brew update
fatal: couldn't find remote ref refs/heads/master
Error: Fetching /opt/homebrew/Library/Taps/dart-lang/homebrew-dart failed!
Error: Some taps failed to update!
The following taps can not read their remote branches:
  dart-lang/dart
This is happening because the remote branch was renamed or deleted.
Reset taps to point to the correct remote branches by running `brew tap --repair`
