I used the pdf package in my Flutter web project. It is completely working while I run it in debug or release mode, but when the web is deployed, it is not working. We can see it is clickable, but nothing happens after clicking. 

Currently, when I click on the button, I can see it is clicked, but nothing happens. I want to generate a pdf while clicking, and this problem only arises when the web is deployed.

I tried to put this code in the index.html file, but nothing happened.

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