Error: The getter 'accentColor' isn't defined for the class 'ThemeData' after updating to Flutter 3.10

I’m getting this error after updating to 3.10, and I don’t reference accentColor in code. I assume it’s one of the libraries that use this line. How do I check which one it is?

Error:

    final borderColor = this.borderColor ?? Theme.of(context).accentColor;
