You get a StreamedResponse for the download. Your question might be incorrect. Perhaps you want a StreamedResponse instead of StreamedRequest, but the link shows that as well. I am using StreamedResponse, but the result is not returned.

The above can be downloaded successfully, but can not return to the download data from time to time, I looked at the data and found that StreamedRequest can be implemented, with StreamedRequest how to achieve the download? I don't think it will help you here. Show 2 more comments. Please write here the solution instead of including a link that could be broken in the future. Here is a sample github.

Even though the browser itself can make HTTP requests anywhere on the web, a Dart web app running inside the browser can make only limited HTTP requests because of security restrictions.

Practically speaking, because of these limitations, HTTP requests from web apps are primarily useful for retrieving information in files specific to and co-located with the app. The example below reads a data file called portmanteaux. When you click the button, the app makes a GET request of the server and loads the file.

Click Run and then click the Get portmanteaux button. This program uses a convenience method, getString , provided by the HttpRequest class to request the file from the server. The getString method uses a Future object to handle the request. A Future is a way to perform potentially time-consuming operations, such as HTTP requests, asynchronously.

Until then, you can use the code above as a guide and provide your own code for the body of the processResponse function and your own code to handle the error. For other cases, you need to create an HttpRequest object, configure its header and other information, and use the send method to make the request. Consider writing a helper function for that if you find the need for downloading files often. Shailen's response is correct and can even be a little shorter with Stream.
