Usage

Install

In your pubspec.yaml, add the following dependencies:

dependencies:
  # dio: ^5.1.0
  # json_annotation: ^4.8.1
  # retrofit: ^4.0.1

dev_dependencies:
  # build_runner: ^2.3.3
  # json_serializable: ^6.6.2
  # retrofit_generator: ^6.0.0
  swagger_parser:

Configure package

Add your OpenApi json file configuration to your pubspec.yaml or create a new config file called swagger_parser.yaml. An example of YAML is shown below

swagger_parser:
  schema_path: assets/openapi.json # Required. Sets the OpenApi schema path directory for api definition
  output_directory: lib/api # Required. Sets output directory for generated files (Clients and Dtos)
  language: dart # Optional. Sets the programming language. Current available languages are: dart, kotlin. Default: dart
  root_interface: true # Optional (dart only). Set 'true' to generate interface with all clients instances. Default: true
  squish_clients: false # Optional. Set 'true' to put all clients in one folder. Default: false
  client_postfix: Client # Optional. Set postfix for Client class and file. Default: Client
  freezed: false # Optional (dart only). Set 'true' to generate data classes using freezed package. Default: false

Run the generator

To generate boilerplate code, run the generate program inside directory where your pubspec.yaml file is located:

dart run swagger_parser:generate

For Flutter projects, you can also run:

flutter pub run swagger_parser:generate

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:generate -f <path to your config file>

Generate files using build_runner for retrofit, json_serializable and freezed

To run the code generation, execute the following command:

dart run build_runner build

For Flutter projects, you can also run:

flutter pub run build_runner build
