It was working a couple months ago and we've had some changes to our codebase but not so much to the database corner of the code. Curious what could have triggered this. Any help appreciated.

You are probably pulling a dart:ui class transitively into one of your DB classes.

Find this line in your project and trace the imports: import 'dart:ui' as ui show Brightness, PlatformDispatcher, SingletonFlutterWindow, window;.

Do any other drift_dev cli commands work.
I wrote the make-migration stuff, but @simolus3 wrote the rest.
need to know if this is my fault

I found the issue, its just not very clear based on the error thrown. One of the models being used as a Table class via implementing drift.Insertable had a helper function that used BuildContext which imported material.dart and in turn dart:ui.

As an improvement you could puke way less on the error and url-decode the dump before you send it to stdout. It took me all day and copying and pasting the error into a separate editor to make sense of it.

This is not your fault whatsoever @dickermoshe! I've added the functionality to make drift_dev run parts of your database code when you export schemas to generally be more reliable (we used to embed snippets of your database code in the exported schema, but running it and storing the result is more resilient against possible changes of your app / its dependencies in the future).

Sorry about that! We've started doing that in (I think) drift_dev version 2.24.0, which one are you on? That version has a command-line flag to export the startup code as a file and falls back to the old approach if spawning the isolate doesn't work. It should also point to this part of the documentation which gives more guidance on how to fix this error.
