Causing issue:-

My base url is without http:// or https// causing the issue 10.0.2.2:4003/api/v1/

Worked for me :-

I only added http:// in URL http://10.0.2.2:4003/api/v1/

you can use https// instead of http//

To avoid such error it's better to define baseUrl while instantiating Dio.

var dio = Dio(); // with default Options

// Set default configs
dio.options.baseUrl = 'https://www.xx.com/api';


// or new Dio with a BaseOptions instance.
var options = BaseOptions(
baseUrl: 'https://www.xx.com/api',
 );
Dio dio = Dio(options);
