I'm working on a Flutter app targeting Android and iOS, using Flutter 3.29.0. I've received user reports of a rendering glitch on a screen containing a ListView. The problem is reported to appear to multiple users using the same phone Samsung A51 5G.
The text inside the ListTile in the ListView is not rendered correctly, as you can see in this image
I've only encountered a similar problem with the app running in debug mode on a Xiaomi Note 11S, but this time the problem is presenting itself with the app built in release mode.
Any idea what could be the cause of this?
The structure of the Widget tree is as follows: ChiamateListScreen -> TabBarView -> ChiamateListTab -> ListView -> ChiamateListItem
