Aqueduct db generate error: Bad state: NoSuchMethodError: The getter 'length' was called on null
It's a bug and it's still there. Happens when there is a previous migration file.
Just erase migrations/00000001_initial.migration.dart and then aqueduct db generate will work as expected.
Tested on Aqueduct 4.0.0-b1
p.s. I know it's the same solution given in the question but I was having the same problem and the solution wasn't clear at first.
You can try to downgrade the Dart version.
brew tap dart-lang/dartbrew uninstall dartbrew install dart@2.8It helped me.
