titleTextStyle property
final
The text style for ListTile's title.
If this property is null, then ListTileThemeData.titleTextStyle is used. If that is also null and ThemeData.useMaterial3 is true, TextTheme.bodyLarge with ColorScheme.onSurface will be used. Otherwise, If ListTile style is ListTileStyle.list, TextTheme.titleMedium will be used and if ListTile style is ListTileStyle.drawer, TextTheme.bodyLarge will be used.
