How to add a swagger dependency in pubspec.yaml of flutter

Question

I'm a new developers with flutter, and i want to use "swagger" in my application. I add the dependencies of swagger in pubspec.yaml, but there's always an error.

pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^0.1.2
  english_words: ^3.1.0
  swagger: ^1.0.0

when i clicked Packages get, this is the following output:

Running "flutter packages get" in my_first_app...               
Because my_first_app depends on swagger ^1.0.0 which doesn't match any versions, version solving failed.

pub get failed (1)
Process finished with exit code 1

How can i use swagger in my Flutter application?

Solution

You probably should use instead

open_api: ^2.0.1

swagger is deprecated and not compatible with Dart 2 and the requested version 1.0.0 doesn't exist at all.

When i change the version of swagger to : swagger: ^0.0.2 this is the following output : Running "flutter packages get" in my_first_app... The current Dart SDK version is 2.1.0-dev.9.4.flutter-f9ebf21297. Because my_first_app depends on swagger >=0.0.2 which requires SDK version >=1.0.0 <2.0.0, version solving failed. pub get failed (1) Process finished with exit code 1

Why would you do that. The package is deprecated and as I said not compatible with Flutter because it depends on Dart 1.

So, i can't use swagger with Flutter ?

Thank you, you mean that openapi dependencies replace swagger dependencies in pubspec.yaml up to now

how to replace swagger in flutter?

Sorry, I don't understand the question. open_api is swagger. Just use open_api
