Have you been turned into a problem with writing code for Http requests? This package can help. It has all of the Http and model codegen functionality you have been looking for.
📣 Build dart types from Swagger/OpenAPI schemas #
SwaggerDartCodeGenerator is a code generator that looks for
*.swagger files and builds
.swagger.dart files, based on the schema. Codegenration based on Chopper and JsonAnnotation models and can be configured for your needs.
In general case for each .swagger file three outputs will be created.
.dart generated by Swagger dart code generator, contains all models, requests, converters, etc.
[Since v1.2.0] .enums.dart generated by Swagger dart code generator, contains all enums and enums mappings.
.chopper.dart - generated by chopper.
.g.dart - generated by json_serializable.
Add the following to your
pubspec.yaml file to be able to do code generation:
dev_dependencies: chopper_generator: ^3.0.5 json_annotation: ^3.0.1 json_serializable: ^3.4.1 swagger_dart_code_generator: any
The generated code uses the following packages in run-time:
dependencies: chopper: ^3.0.3
pub packages get
flutter packages get
Now SwaggerGenerator will generate the API files for you by running:
pub run build_runner build
flutter pub run build_runner build
Swagger generator offers some configuration options to generate code. All options should be included on
build.yaml file on the root of the project:
targets: $default: builders: swagger_dart_code_generator: options: # custom configuration options!
|Option||Default value||Is required||Description|
|If this option is false, generator will ignore base url in swagger file.|
|If option is true, combination of all mappings will be generated.|
|If option is true, headers will not be generated.|
|If property == |
|If value is false, 'enumValue' will be defined like Enum.enumValue even it's json key equals 'ENUMVALUE'|
|If option is true, default value for lists will be null, otherwice - |
|If option is true, chopper classes will not be generated.|
|Enables or disables includeIfNull JsonAnnotation feature and sets value for it. See IncludeIfNull.|
|Contains map of types and theirs default values. See DefaultValueMap.|
|Contains map of responses and theirs overriden values. See ResponseOverrideValueMap.|
|Path to folder with .swagger files (for ex. swagger_examples, or lib/swaggers).|
|Path to output folder (for ex. lib/generated).|
It's important to remember that, by default, build will follow Dart's package layout conventions, meaning that only some folders will be considered to parse the input files. So, if you want to reference files from a folder other than
lib/, make sure you've included it on
targets: $default: sources: - lib/** - swagger_examples/** - swaggers/**
IncludeIfNull for model generation #
This option is used to add includeIfEmpty annotation for model fields. If option not enabled or empty - includeIfNull annotation will not added to fields. For mode details see oficial documentation Please see next example:
targets: $default: builders: swagger_dart_code_generator: options: input_folder: 'lib/swaggers' output_folder: 'lib/generated_code/' include_if_null: enabled: true value: false
Default Value Map for model generation #
If you want to add defaultValue: attribute to fields with concrete type you can use default value map. Please see next example:
targets: $default: builders: swagger_dart_code_generator: options: input_folder: 'lib/swaggers' output_folder: 'lib/generated_code/' default_values_map: - type_name: int default_value: '36' - type_name: String default_value: 'defaut' - type_name: 'List<String>' default_value: ''
Response Override Value Map for requests generation #
If you want to override response for concrete request, you can use response_override_value_map. For example:
targets: $default: builders: swagger_dart_code_generator: options: input_folder: 'lib/swaggers' output_folder: 'lib/generated_code/' response_override_value_map: - url: '/store/inventory' method: get overriden_value: 'List<dynamic>' - url: '/news/latest' method: put overriden_value: 'MyPerfectType'
Check the examples to see how to use it in details.
