Here's the answer I've given at the time:

You might wanna give a try to the dio package it is an http client that supports file downloading and save it locally to a given path.

Here's a code sample (source: iampawan's Github )

Future downloadFile(String url) async {
  Dio dio = Dio();

  try {
    var dir = await getApplicationDocumentsDirectory();
    await dio.download(url, "${dir.path}/myFile.txt", onProgress: (rec, total) {
      print("Rec: $rec , Total: $total");
    });
  } catch (e) {
    print(e);
  }
  print("Download completed");
}

You will also need path_provider tu use getApplicationDocumentsDirectory() .
