There was an issue with FastaVerifyingVisitor which I had not updated.

[error] Invalid override. The type of 'FastaVerifyingVisitor.problem'
('(TreeNode, String) → dynamic') isn't a subtype of 'VerifyingVisitor.problem'
('(TreeNode, String, {context: TreeNode}) → dynamic').
(package:front_end/src/fasta/kernel/verifier.dart, line 47, col 3)
