How to pass along the password

[reddeath1]

Hello I m currently using this, package on my app, then migrate to the new one.. my app is it's completion stage,
But the issue is once it's in production all pdf will be password protected and I don't want users to be prompted to enter passwords which they don't even have. so the question is how to pass the password along on this methods.

PdfDocument doc = isFile
? await PdfDocument.openFile(f)
: await PdfDocument.openData(uint8List);

pdf_render could not support password because the backend for Android is PdfRenderer and it does not support password.

Thank you, what are your recommendations. As I once wanted to use pdfrx but failed due to compatibility issues.

[espresso3389]

What is your compatibility issue?

[reddeath1]

Kindly see the screenshot.

@reddeath1 Could you give me your flutter doctor -v? Are you on Flutter 3.12.0/Dar 3.1.0?

[reddeath1]

flutter doctor -v
[√] Flutter (Channel stable, 3.13.0, on Microsoft Windows [Version 10.0.22621.3155], locale en-AS)
    • Flutter version 3.13.0 on channel stable at D:\SERVER\flutter

Just a rough testing, but if I change pdfrx's pubspec to support Flutter 3.12.0/Dart 3.1.0, it works well except Web.

name: pdfrx
description: pdfrx is a rich and fast PDF viewer implementation built on the top of pdfium. The plugin supports Android, iOS, Windows, macOS, Linux, and Web.
version: 0.4.46
homepage: https://github.com/espresso3389/pdfrx

environment:
  sdk: '>=3.1.0 <4.0.0'
  flutter: '>=3.12.0'

[reddeath1]

Thank you, I m not using the web version.. let me do that, and revert back.

[reddeath1]

Quick question

do I change all these

environment:
sdk: '>=3.3.0 <4.0.0'
flutter: '>=3.19.0'

or just flutter.

[espresso3389]

You should change both.

[espresso3389]

Oh, please use 0.4.X branch.

[reddeath1]

Thank you as the current version has issues. Also I have a question is 0.4.X brand has all upgrade from current version?

`Resolving dependencies...
Note: web is pinned to version 0.1.4-beta by flutter from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.

Because every version of pdfrx from git depends on web ^0.5.0 and every version of flutter from sdk depends on web 0.1.4-beta, pdfrx from git is incompatible with flutter from sdk.
So, because egazeti depends on both flutter from sdk and pdfrx from git, version solving failed.`

[espresso3389]

Mmm, I'm testing it on Dart 3.1.0, but NativeCallable.listener at least requires 3.2.0...

[reddeath1]

I just downloaded latest flutter, but ran onto big issue.. I think will recall the previous one and replan the upgrade.

I'm still working on a workaround on Flutter 3.13.0.

[reddeath1]

I manage to narrow down the errors by upgrading other plugins as well and started to work till this came.
