DioError [DioErrorType.other]: Converting object to an encodable object failed: Instance of 'Future<dynamic>'

[fradrick]

I am having a challenge implementing a post request:

var dio = Dio(); Response response = await dio.post('http://127.0.0.1:8000/api/login', data: { "username": _username, "password": _password, }); print("The response"); print(response); return;

But I am always getting this error:

你找到这个问题的原因了吗？我也出现了这个问题，但是不知道怎么解决
