My issue is about [Mobile]

SVID_20220215_225106_1.mp4

If the content ends with a newline break, then select all, then select cut it will report an error

If you have a VERY long amount of text, and even highlight just a piece of it and delete, you will get a RSOD (red screen of death)

Me too, the same problem

[jonasbernardo]

please someone correct this bug

[jonasbernardo]

I tried to find the problem, so I checked the method ChildQuery queryChild(int offset) in class Document.dart
is returning wrong values ​​when selecting text with line break \n

I think that's it but I don't know how to fix it

[mtallenca]

version 4.0.7 addresses this
