Classes
-
BackgroundTransformer
-
The default Transformer for Dio.
-
BaseOptions
-
A set of base settings for each
Dio().
BaseOptions and Options will be merged into one RequestOptions before
sending the requests. See Options.compose.
-
CancelToken
-
Controls cancellation of Dio's requests.
-
Dio
-
Dio enables you to make HTTP requests easily.
-
DioHttpEngine
-
-
DioMixin
-
-
ErrorInterceptorHandler
-
The handler for interceptors to handle error occurred during the request.
-
FormData
-
A class to create readable "multipart/form-data" streams.
It can be used to submit forms and file uploads to http server.
-
FusedTransformer
-
A Transformer that has a fast path for decoding UTF8-encoded JSON.
If the response is utf8-encoded JSON and no custom decoder is specified in the RequestOptions, this transformer
is significantly faster than the default SyncTransformer and the BackgroundTransformer.
This improvement is achieved by using a fused Utf8Decoder and JsonDecoder to decode the response,
which is faster than decoding the utf8-encoded JSON in two separate steps, since
Dart uses a special fast decoder for this case.
See https://github.com/dart-lang/sdk/blob/5b2ea0c7a227d91c691d2ff8cbbeb5f7f86afdb9/sdk/lib/_internal/vm/lib/convert_patch.dart#L40
-
The headers class for requests and responses.
-
HttpClientAdapter
-
HttpAdapter is a bridge between Dio and HttpClient.
-
IHttp
-
-
Interceptor
-
Interceptor helps to deal with RequestOptions, Response,
and DioException during the lifecycle of a request
before it reaches users.
-
Interceptors
-
A Queue-Model list for Interceptors.
-
InterceptorsWrapper
-
A helper class to create interceptors in ease.
-
ListParam<T>
-
Indicates a param being used as queries or form data,
and how does it gets formatted.
-
LogInterceptor
-
LogInterceptor is used to print logs during network requests.
It should be the last interceptor added,
otherwise modifications by following interceptors will not be logged.
This is because the execution of interceptors is in the order of addition.
-
MultipartFile
-
An upload content that is a part of
MultipartRequest.
This doesn't need to correspond to a physical file.
-
Options
-
The configuration for a single request.
BaseOptions and Options will be merged into one RequestOptions before
sending the requests. See Options.compose.
-
QueuedInterceptor
-
Interceptor in queue.
-
QueuedInterceptorsWrapper
-
A helper class to create QueuedInterceptor in ease.
-
RedirectRecord
-
A record that records the redirection happens during requests,
including status code, request method, and the location.
-
RequestInterceptorHandler
-
The handler for interceptors to handle before the request has been sent.
-
RequestOptions
-
The internal request option class that is the eventual result after
BaseOptions and Options are composed.
-
Response<T>
-
The Response class contains the payload (could be transformed)
that respond from the request, and other information of the response.
-
ResponseBody
-
The response wrapper class for adapters.
-
ResponseInterceptorHandler
-
The handler for interceptors to handle after respond.
-
ResponseResult<T>
-
-
SyncTransformer
-
If you want to custom the transformation of request/response data,
you can provide a Transformer by your self, and replace
the transformer by setting the Dio.transformer.
-
Transformer
-
Transformer allows changes to the request/response data before
it is sent/received to/from the server.
Enums
-
DioExceptionType
-
The exception enumeration indicates what type of exception
has happened during requests.
-
FileAccessMode
-
The file access mode when downloading a file, corresponds to a subset of
dart:io::FileMode.
-
ListFormat
-
Specifies the array format (a single parameter with multiple parameter
or multiple parameters with the same name).
and the separator for array items.
-
RequestMethod
-
-
ResponseType
-
Indicates which transformation should be applied to the response data.
