of static method
- BuildContext context
Retrieves the ExpansionTileThemeData from the closest ancestor ExpansionTileTheme.
If there is no enclosing ExpansionTileTheme widget, then ThemeData.expansionTileTheme is used.
Typical usage is as follows:
ExpansionTileThemeData theme = ExpansionTileTheme.of(context);
Implementation
static ExpansionTileThemeData of(BuildContext context) {
final ExpansionTileTheme? inheritedTheme = context
.dependOnInheritedWidgetOfExactType<ExpansionTileTheme>();
return inheritedTheme?.data ?? Theme.of(context).expansionTileTheme;
}
