I've published the sample #FlutterDev implementation of "blackboard and chalk" expression. Visit the GitHub repo below and enjoy CustomPainter and fragment shader! (my draw_your_image package also) github.com/chooyan-eng/ch…

Github: github.com/ben-milanko/da… App Demo: app.dart-pdf.com

dart_pdf_editor 3.1.0 is out. Fewer dropped frames on large, visually dense PDFs, responsive rapid scrolling, and page previews that stay visible until full-detail rendering catches up. Here's the 3 piece demo. (All in Flutter web too)

@hurelhuyag Hmm yeah I think we can be greedier with RAM and also make better use of idle time to pre-process out of view sheets. I also thinking more disk caching could be good if RAM is constrained.

@BenMilanko Is there a way to keep rendered pages cached, even if it uses 5 GB of RAM? It seems to discard them even when there's plenty of free memory available.

DartPDF 2.1.0 is out I've been working on the performance: - dense pages scroll without stalling - saves append, not full rewrites - O(1) page + widget lookups If you have a heavy / slow / janky PDF, devtools is opened with F12 and the PdfPerfLog can help diagnose.

@hurelhuyag Let me know how you go!

@BenMilanko Nice. I wanna test it with big technical drawings. Most pdf readers too slow to use.

Library is pure Dart end to end. Parser, renderer and editor, no platform PDF engine. github.com/ben-milanko/da…

@pavanpodila Yes! always happy to chat

@BenMilanko We should chat and exchange notes if you are up for it

Making progress on the Document Editor, built entirely in #Flutter. Inspired by a variety of such solutions across the web. There are still many bugs here and there, and a lot more polishing is required in some areas. The core document model, actions, commands, undo/redo stack, and core inline geometries, line geometries, paragraph, sections, are in place. We're expanding our support for more table editing features and fixing a variety of bugs. I'll make this editor online for public testing once we reach more stability. #vyuh #document #editor

@awrsqx @devangelslondon Yeah a sample PDF would help thanks

@BenMilanko @devangelslondon Looks good, but I think this introduced an issue with Arabic search. Searching for Arabic words now returns 0 results. Also, copying words with tashkil adds spaces between each letter (plain Arabic works fine). Let me know if you'd like me to open an issue with a sample PDF.

I've spent the last few releases making Dart PDF much faster on large files. Here's 1.0.0 vs 1.4.1 scrolling the same PDF, to the same point.

@devangelslondon @awrsqx Thanks for the pointer. The new PR for this is up github.com/ben-milanko/da…

@awrsqx @BenMilanko It can, you need to insert bidi characters. See w3.org/International/…

@awrsqx Hey I've raised a PR for this, could you let me know how it looks now? There's a link to the PR preview channel demo app in the PR. github.com/ben-milanko/da…

@BenMilanko Great work! I noticed an issue that's common across PDF packages in Dart. Arabic text is reversed when copied or searched. I tested your package and saw the same behavior. Could you look into fixing it? Here's an example from an issue I opened in pdfrx: github.com/espresso3389/p…

@BenMilanko packge link?

💙 Introducing gputext 💙 ​Built on the Windfoil algorithm (an improved variant of Slug), gputext enables ultra-fast, scalable text rendering by offloading text shaping and rasterization directly to the GPU. ​Check it out here: 🔰

@definev2 @jezell @SuprDeclarative I think I might have to check out flutter_gpu for pdf rendering! My bottleneck at the moment is the Flutter raster.

The Clay algorithm looks really good! cc: @jezell @SuprDeclarative

Experimenting use the windfoil algorithm to serve as the backend for the RichText widget :-) It looks much sharper and more refined than the default RichText. It might even fix the issue at github.com/flutter/flutte…. #flutter #flutter_gpu

What's the most ambitious project you have Fable working on right now?

Here is the post I mentioned! @jacobtechtavern creates truly top-notch content 🔥🔥🔥
