    pdfTitle = "PDF Title",
    saveTo = PdfViewerActivity.saveTo.ASK_EVERYTIME,
    enableDownload = true

To open a PDF stored in local storage:

/* Parameters:
- path: File path or URI of the local PDF.
- fromAssets: Set to false when loading from local storage. // FALSE by default

    context = this,
    path = "your_file_path_or_uri_here",
    pdfTitle = "Title",
    saveTo = PdfViewerActivity.saveTo.ASK_EVERYTIME,
    fromAssets = false

  fromAssets = true

Loading PDF in a View

Load a PDF directly into a view:

Add PDF render view in your layout file

    app:pdfView_showDivider="false" />

and in your kotlin file

  url = "your_pdf_url_here",
