I'd like to recommend dio package to you , dio is a powerful Http client for Dart/Flutter, which supports Interceptors, FormData, Request Cancellation, File Downloading, Timeout etc.

dio is very easy to use:

Performing a Get request:

response=await dio.get(url)

Performing a POST request:

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

Sending FormData:

FormData formData = new FormData.from({
   "name": "wendux",
   "file1": new UploadFileInfo(new File("./upload.pdf"), "upload1.pdf")
});
response = await dio.post("/info", data: formData)

Downloading a file:

response=await dio.download("https://www.google.com/","./xx.html")
