QUESTION
The goal is to render pages of a pdf to an offsrceen canvas to that I can copy portions of the page to a visible canvas. As a first step, the code below is intended to render the entire first page of a pdf. It renders to an offscreen canvas, then copies from offscreen to the visible canvas. Or that was my intention. Nothing appears.
...ANSWER
Answered 2022-Mar-23 at 19:45The code below does what was intended. I am still uncertain why the original code fails to work. My best guess is that it's due to something being done asynchronously.There's very little that's different about the two implemenations aside from that.
QUESTION
I need to a open pdf file from the local storage, here i use native_pdf_renderer: ^3.1.0 package for this purpose. As per the documentation, using the method PdfDocument.openFile('path/to/file/on/device')
will fetch file from local storage. But In my case it doesn't work, show's an error PlatformException (PlatformException(PDF_RENDER, Can't open file, null, null))
. The other methods PdfDocument.openAsset('assets/sample.pdf')
and PdfDocument.openData(uint8Data)
work's fine. How can this be made to work?

...ANSWER
Answered 2021-Aug-24 at 05:51I got the solution:
The error occurs because of incomplete download of NDK hence the source.properties is missing.
Solution: go to the ndk directory and delete the corresponding folder
In my case the path was D:\Resources\AndroidStudioSDK\ndk\21.4.7075529
, I deleted the folder 21.4.7075529
. You can find the ndk folder path in the error message itself.
After deleting the folder execute the app, the ndk fresh download will start again.
Let it complete and the problem is solved !!!
QUESTION
I am working on a iOS/Android/Web app where I am generating a PDF based on user input using the pdf plugin here: https://pub.dev/packages/pdf. On iOS and Android, I have access to the file system, so I am able to save the generated pdf first, and then open it with any pdf display plugin.
However, for Flutter web, as far as I know, there is no access to any type of file system. All the pdf render plugins that I've seen assume that the pdf file is either stored in a file, or on the web. I looked at:
- flutter_full_pdf_viewer: ^1.0.6
- flutter_pdf_viewer: ^0.6.1
- pdf_render: ^0.57.2
How can I display this app-generated pdf on flutter web? Is there a way to spoof the Uint8List data as a file, or perhaps another way to approach this? (The only thing I can think of to solve this is by uploading the file to the web after generating it in order to display it, but it seems like overkill.)
...ANSWER
Answered 2020-Apr-23 at 19:58We can do it without additional plug-ins, because the web browser itself can display (or download) pdf
