Hello @chifandeyu. Thank you for filing this issue. Can you please provide the following information?

• A complete and minimal, reproducible example. Ideally, a single main.dart file that can be run directly.
• The output of flutter run -v

Please provide the information in the form of text. See how to make collapsible sections with Markdown here.

Sorry. The call stack from users through the exception reporting system. Crashing randomly in use, and our project has many components.

[exaby73]

Alright thank you for the information. I'll label this issue for insights and investigation from the team

[chifandeyu]

Analysis from the user feedback. Rendering to the text contains special characters. The overflow is set to the textoverflow.ellipsis.

[chifandeyu]

estext.txt

This is the special text that we have rendered. @exaby73

[Rusino]

Thank you. Special text + ellipsis. I am going to work on it.

Thank you. Special text + ellipsis. I am going to work on it.

Maybe my description is wrong. This one has a stack that is the same as the crash reproduce #https://github.com/flutter/flutter/issues/109825
