How can i download the file

[prasanmoonraft]

with import 'dart:html' as html;
was using this
html.AnchorElement(href: url)
// Set the download attribute to file name.
..setAttribute("download", "")
// Trigger a click event on the anchor element to initiate the download.
..click();
and it's was working absolutely fine

how it'll work with web package

It's useful to look at the dart:html source code here to compare. The code should be similar. The only difference is that the AnchorElement constructor in dart:html took in an href that it explicitly set (well that and the rename of the type).

import 'package:web/web.dart' as web;
...
var anchorElement = web.HTMLAnchorElement()
  ..href = url
  ..setAttribute('download', '')
  ..click();

For Android build it's failing how we can use this as web and don't fail the android build
The unavailable library 'dart:js_interop' is imported through these packages:

I'll need a bit more information, but if you're compiling to native, dart:js_interop is unavailable as it's not a web platform.
