useTheme function
A composable that returns the current ThemeData from the widget tree.
This is a convenient way to access theme properties within a Kaeru composable.
It uses useContext to get the current BuildContext and then retrieves the theme.
Example:
KaeruWidget((ref) {
final theme = useTheme();
return KaeruBuilder(() {
return Text(
'The primary color is ${theme.$.primaryColor}',
style: TextStyle(color: theme.$.colorScheme.secondary),
);
});
});
Implementation
Computed<ThemeData> useTheme() {
final context = useContext();
final compute = computed(() => Theme.of(context));
onDependenciesChanged(() => compute.onChange());
return compute;
}
