ignite generate dart fails on freshly scaffolded chain

[jaredweinfurtner]

Describe the bug

When trying to generate the Dart client on a freshly scaffolded chain, I always receive the error:

cannot build app:

Hi, @jaredweinfurtner, ignite generate dart functionality is no longer maintained by the team as we have changed size and prioritize other features.
