build JsonSerializable models in sub-modules with build_runner

Question

I have a Flutter project with sub-modules:

- root Flutter project
  - Flutter module 1
  - Flutter module 2
  ...
  - Flutter module N

Each module contains classes annotated with @JsonSerializable().

Currently i build models with this script:

for dir in [DIR_LIST]
do
  echo "Building models in ${dir}"
  cd ${BASE_DIR}/${dir}
  flutter packages pub run build_runner build --delete-conflicting-outputs
done

Is there a way to build every sub-module in my project with a single command in the root directory instead of cycle each directory?

Answer 1

In your build.yaml file

1. Specify sources for your modules

2. Add them in generate_for block

    targets:
     $default:
       builders:
        json_serializable|json_serializable:
          generate_for:
            - "modules/data_module/**.dart"
      sources:
        - "lib/**"
        - "test/**"
        - "modules/data_module/**"
