Since my app allows to compose widget trees by user edit operations, I'd like to catch render errors: If the user inserts a non-fitting widget which renders an error, the app should undo the last insert operation.
I specifically need to catch Exceptions caught by the widgets library:
I did find the Handling Errors in Flutter section. Unfortunately, this section doesn't explain how to catch render errors.
Could you provide a code sample for this?

I have a code which can be seen here
trying to debug it I got this error, I don't know where I made mistake in the Obx function as started by flutter.
Try to wrap the Scaffold into Obx if you need to update the state on whole widget tree or the ListTile to Update the specific widget.

After these codes create a screenshot, an image is created at the bottom. This is the code I implemented because I wanted to drag the created image after that.
However, an error occurs during execution and the code cannot be executed. Please help me to get my code to run fine.
Add the _bytes null-check on Positioned too:
if (bytes != null)
Positioned(...)

call-for-help: we are keep getting the illustrated error after hitting "save changes" in the application settings dashboard ... the changes are saved though ... any link where we can report our app issue?

This is not a problem with your app..
This happens sometimes because your app server might have taken a longer time to update on FB servers and the connection timed out...
Nothing to worry about you an try again
I had the same issue and solved it by checking all the icons and screenshots. I made sure that they all was in the same format (.png) and then it worked!
I guess the issue, for me, is that i used different formats.
