build_runner does not generate mappings

[xErik]

The build_runner does not generate the mapping file(s).
I created a test project with a PODO Bla, which the build_runner ignores.

(You mention to install dart_mappable, but give flutter pub add super_annotations. This is probably a leftover from your other project.)

I am new to flutter, the solution might be trivial.

Oh yes, this is wrong.

targets:
  $default:
    builders:
      dart_mappable:
        generate_for:
          - lib/main.dart
        options: # tried with and without class option
        - include: [Bla] 

This should be in the build.yaml file, not the pubspec.yaml.

Silly mistake, sorry.
Still struggling a bit with the whole flutter ecosystem.
Thank you!
