How to load the pdf scripts and packages deferred

[razfazz]

I was able to load the flutter_pdf_render deferred by using

import 'package:pdf_render/pdf_render_widgets.dart' deferred as pdf;

But the main problem which delays the initial load time is the section inside the index.html

<script
        src="https://cdn.jsdelivr.net/npm/pdfjs-dist@2.12.313/build/pdf.js"
        type="text/javascript"
></script>
<script type="text/javascript">
  pdfjsLib.GlobalWorkerOptions.workerSrc =
    "https://cdn.jsdelivr.net/npm/pdfjs-dist@2.12.313/build/pdf.worker.min.js";
  pdfRenderOptions = {
    // where cmaps are downloaded from
    cMapUrl: "https://cdn.jsdelivr.net/npm/pdfjs-dist@2.12.313/cmaps/",
    // The cmaps are compressed in the case
    cMapPacked: true,
    // any other options for pdfjsLib.getDocument.
    // params: {}
  };
</script>

Is it possible to load the javascript files also async from dart?

Similar to the following template section

import 'dart:async';
import 'dart:html';

Future<void> loadJavascriptFile() async {
  // Create a ScriptElement
  var jsScript = new ScriptElement();
  jsScript.src = 'path/to/javascript/file.js';

  // Wait for the load event to complete
  await jsScript.onLoad.first;

  // Call a function from the loaded JavaScript file
  context['myFunction'].callMethod('apply', [context, ['arg1', 'arg2']]);
}

void main() async {
  // Call the async function to load the JavaScript file
  await loadJavascriptFile();
}

Thank you for your help in advance and this would be a great achievement to reduce the initial loading time.
