Dio dio = new Dio();

response = await dio.get("/test?id=12&name=wendu");
print(response.data.toString());

// Optionally the request above could also be done as
response = await dio.get("/test", queryParameters: {"id": 12, "name": "wendu"});
print(response.data.toString());

Performing a POST request:

response = await dio.post("/test", data: {"id": 12, "name": "wendu"});

Performing multiple concurrent requests:

response = await Future.wait([dio.post("/info"), dio.get("/token")]);

Downloading a file:

Dio APIs

Creating an instance and set default configs.

You can create an instance of Dio with an optional BaseOptions object:

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

// Set default configs
dio.options.baseUrl = "https://www.xx.com/api";
dio.options.connectTimeout = 5000; //5s
dio.options.receiveTimeout = 3000;

// or new Dio with a BaseOptions instance.
BaseOptions options = new BaseOptions(
    baseUrl: "https://www.xx.com/api",
    connectTimeout: 5000,
    receiveTimeout: 3000,
);
Dio dio = new Dio(options);
