debugDisposed and debugDuringDeviceUpdate errors during debug

[Pietro Beccegato]

I've got a flutter web app with many different widgets.

Basically there's a sfDatagrid on the left and an hidden sfPdfViewer on the right.

When the user make a double tap on a sfDatagrid's row, if the sfPdfViewer on the right is not yet visible, the main widgets is rebuild and the sfPdfViewer is shown.

Everything works fine into the builded app, but when I test in debug mode, I've got an error as following, the app still hang and I have to stop the app.

════════ Exception caught by scheduler library ═════════════════════════════════
The following assertion was thrown during a scheduler callback:
Assertion failed:

is not true




When the exception was thrown, this was the stack

I tried in different ways to edit my code, but I can't solve the problem. I also try to make a sample app to reproduce the error to send to you, but I can't reproduce the error in other app.

The error is fired by code at line 959.

I attach to this post my dart code and a screenshot of my app, hoping can help you to suggest me something to check.

This issue make me crazy in the last 4 days, so each help will be appreciated.
