Code partially generated with chopper
SwaggerDartCodeGenerator is a code generator that looks for *.swagger
files and builds .swagger.dart
files, based on the schema. Code generation 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.
The generated code uses the following packages in run-time:
dependencies:
chopper: ^4.0.1
json_annotation: ^4.1.0
Add the following to your pubspec.yaml
file to be able to do code generation:
dev_dependencies:
build_runner: ^2.1.4
chopper_generator: ^4.0.2
json_serializable: ^5.0.0
swagger_dart_code_generator: any
Then run:
pub packages get
or
flutter packages get
Now SwaggerGenerator will generate the API files for you by running:
pub run build_runner build
or
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 |
---|---|---|---|
with_base_url |
true |
false |
If this option is false, generator will ignore base url in swagger file. |
use_required_attribute_for_headers |
true |
false |
If this option is false, generator will not add @required attribute to headers. |
with_converter |
true |
false |
If option is true, combination of all mappings will be generated. |
ignore_headers |
false |
false |
If option is true, headers will not be generated. |
enums_case_sensitive |
true |
false |
If value is false, 'enumValue' will be defined like Enum.enumValue even it's json key equals 'ENUMVALUE' |
include_paths |
[] |
false |
List of Regex If not empty - includes only paths matching reges |
exclude_paths |
[] |
false |
List of Regex If not empty -exclude paths matching reges |
use_default_null_for_lists |
false |
false |
If option is true, default value for lists will be null, otherwise - [] |
build_only_models |
false |
false |
If option is true, chopper classes will not be generated. |
separate_models |
false |
false |
If option true, generates models into separate file. |
include_if_null |
null |
false |
Sets includeIfNull JsonAnnotation feature and sets value for it. If null - not set anything. |
default_values_map |
[] |
false |
Contains map of types and theirs default values. See DefaultValueMap. |
response_override_value_map |
[] |
false |
Contains map of responses and theirs overridden values. See ResponseOverrideValueMap. |
input_folder |
- |
true |
Path to folder with .swagger files (for ex. swagger_examples, or lib/swaggers). |
output_folder |
- |
true |
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 sources
:
targets:
$default:
sources:
- lib/**
- swagger_examples/**
- swaggers/**
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: 'default'
- type_name: 'List<String>'
default_value: '[]'
exclude_paths:
- '\/cars\/get'
include_paths:
- '\/popular\/cars'
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
overridden_value: 'List<dynamic>'
- url: '/news/latest'
method: put
overridden_value: 'MyPerfectType'
Check the examples to see how to use it in details.
