PDF library
Unfortunately i couldn't figure it out because i'm using dart:html
If you want to output a Flutter scene exactly as they appear on the screen, you can use a RepaintBoundary widget, to save the widget into a PNG file.
You can insert RepaintBoundary at any level of the widget tree. So if you put it near the root of the widget tree, you will be able to capture the whole screen.
Take a look at this answer for how to use RepaintBoundary.

Flutter: Make text/images selectable in whole web app

In the Flutter web apps, there is no default functionality which makes text and images in the app selectable.
Is there a way to enable selection functionality for text/image on web?
I did check SelectableText widget but it is only for text and I would need to use it over every text. Also, you can't select text in multiple SelectableText widgets at once, you can only select text in one of them. I'm looking for a solution to select all text in the app without making change to every text widget.
Let me know if there’s one step solution to achieve this thing in whole web app.
In Flutter 3.3, with the introduction of the SelectableArea widget, any child of the SelectableArea widget has selection enabled for free!
To take advantage of this powerful new feature, simply wrap your route body (such as the Scaffold) with the SelectionArea widget and let Flutter do the rest.
For a more comprehensive deep dive into this awesome new feature, please visit the SelectableArea API page.
Flutter Web currently does not support multiple text selection across SelectableText widgets.
However, there are some experimental widgets that people are currently working on. According to a guide available at:
Custom SelectableScope Widget
They have proposed a custom widget, a Selectable scope, which basically allows for anything within it to be selectable (currently text and images)
NOTE: THIS IS CURRENTLY UNDER EXPERIMENTATION AND MIGHT CHANGE AS MENTIONED IN THE PROVIDED LINK.
