I am using latest version of flutter, with latest version of Xcode, with latest version of android studio. I also have charts_flutter: ^0.12.0 but I am getting the error :

Launching lib/main.dart on iPhone 15 Pro Max in debug mode...
Xcode build done.                                            3,9s
Failed to build iOS app
Error (Xcode): ../.pub-cache/hosted/pub.dev/charts_flutter-0.12.0/lib/src/behaviors/legend/legend_entry_layout.dart:134:45: 
Error: The getter 'bodyText2' isn't defined for the class 'TextTheme'.

Could not build the application for the simulator.
Error launching application on iPhone 15 Pro Max.

I tried flutter upgrade, flutter doctor, but everything is right and up to date.
I do not understand why I have an error, and therefore do not know how to solve it after many stack overflow posts.
