of static method
Returns the data from the closest NavigationPaneTheme ancestor. If there is no ancestor, it returns ThemeData.navigationPaneTheme. Applications can assume that the returned value will not be null.
Typical usage is as follows:
NavigationPaneThemeData theme = NavigationPaneTheme.of(context);
Implementation
static NavigationPaneThemeData of(BuildContext context) {
return FluentTheme.of(context).navigationPaneTheme.merge(
_getInheritedThemeData(context),
);
}
