swagger_parser:
# <...> Set default parameters for all schemes.
output_directory: lib/api
squash_clients: true

# Optional. You can pass a list of schemes.
# Each schema inherits the parameters described in swagger_parser,
# any parameter for any schema can be set manually.
# Cannot be used at the same time as schema_path.
schemes:
- schema_path: schemes/openapi.json
root_client_name: ApiMicroservice

Run the generator #
To generate code, run the swagger_parser program inside directory where your pubspec.yaml file is located:
dart run swagger_parser
copied to clipboard
If you name your configuration file something other than swagger_parser.yaml or pubspec.yaml
you will need to specify the name of the YAML file as an argument.
dart run swagger_parser -f <path to your config file>
copied to clipboard
(Only for freezed) Generate files using build_runner for retrofit, json_serializable and freezed #
For freezed with retrofit use build.yaml file with this content:
global_options:
freezed:
runs_before:
- json_serializable
json_serializable:
runs_before:
- retrofit_generator
copied to clipboard
To run the code generation with build_runner, execute the following command:
dart run build_runner build -d
