dio_http_formatter 2.1.0

A simple Dio interceptor for pretty printing the HTTP request/response (using the awesome package Logger) to be printed in the console for easier debugging and sharing.

Different content types are supported and pretty printed such as:

application/json
application/x-www-form-urlencoded
text/html

Getting started #

1- Install the package in your project:

flutter pub get dio_http_formatter

or if not for Flutter:

pub get dio_http_formatter

2- Add the interceptor to your Dio instance like:

final _dio = Dio();
_dio.interceptors.add(HttpFormatter());

Options #

Below are the optional parameters that can be specified for the formatter to customize what and how the HTTP request and response is printed.

Property	Type	Default Value
includeRequest	`bool`	`true`
includeRequestHeaders	`bool`	`true`
includeRequestQueryParams	`bool`	`true`
includeRequestBody	`bool`	`true`
includeResponse	`bool`	`true`
includeResponseHeaders	`bool`	`true`
includeResponseBody	`bool`	`true`
logger	`Logger`	`PrettyPrinter()`

Examples #

POST request [application/json] #

  await _dio.post('https://postman-echo.com/post',
      data: <String, dynamic>{'foo': 'foo'},
      options: Options()
        ..headers = <String, dynamic>{
          'my-custom-header': 'my-custom-header',
