ExpansionTileThemeData class Null safety
Used with ExpansionTileTheme to define default property values for descendant ExpansionTile widgets.
Descendant widgets obtain the current ExpansionTileThemeData object
using ExpansionTileTheme.of(context). Instances of
ExpansionTileThemeData can be customized with
ExpansionTileThemeData.copyWith.
A ExpansionTileThemeData is often specified as part of the overall Theme with ThemeData.expansionTileTheme.
All ExpansionTileThemeData properties are null by default.
When a theme property is null, the ExpansionTile will provide its own
default based on the overall Theme's textTheme and
colorScheme. See the individual ExpansionTile properties for details.
See also:
- ThemeData, which describes the overall theme information for the application.
- ExpansionTileTheme which overrides the default ExpansionTileTheme of its ExpansionTile descendants.
- ThemeData.textTheme, text with a color that contrasts with the card and canvas colors.
- ThemeData.colorScheme, the thirteen colors that most Material widget default colors are based on.
