Nice if the app could have a text feature to be added so that the user can add and edit text on canvas.

When i test the project, try add shape or line in backgroud. After i saved it and check the images, the shape or line is appear, but the background or image that added not appear. I want to fixed that but the backgroundImage not null when added images, make me really confuse

Trying to run this project but I'm getting this error Not found: 'dart:js'

I'm running this on Flutter 3.3.2 and haven't done anything extra on the project. How to fix?

When I run this on mobile it does not export the image. What should I update in the code to do that?

I'm trying to implement a collaborative whiteboard. For that to work efficiently, I need to be able to get access to all points and lines drawn on the canvas. Is it possible to do that? Or at least get the SVG output of the canvas?

If import a background it not keep original proportion but are dragged to the outher edges of the screen/canvas.

Would be useful as well with a option to calibrate and eventually rotate and lock/unlock the bacground. This so that it could be traceable in real proportions or measures.

The File Saver plugin failed to save on Windows, I recommend the FIleSaver plugin is replaced with a more robust solution
