The changelog of the flutter_markdown package is a bit confusing. First it says:

Updates minimum supported SDK version to Flutter 3.10/Dart 3.0

and in the latest update is says

Updates minimum supported SDK version to Flutter 3.7/Dart 2.19

Just from reading this I would expect that the minimum SDK lowered with the latest update. However, this is not the case.

After a bit of researching, I found this was caused by flutter/packages#4731. The PR only updates the minimum SDK of the example but not of the package, see: https://github.com/flutter/packages/pull/4731/files#diff-e780ee3aec5fdc10512b452b5464878a11caf22fb23d28f725324308ad243d17R6
