maybeOf static method
- BuildContext context
The closest instance of DefaultTextHeightBehavior that encloses the given context, or null if none is found.
If no such instance exists, this method will return null.
Calling this method will create a dependency on the closest
DefaultTextHeightBehavior in the context, if there is one.
Typical usage is as follows:
TextHeightBehavior? defaultTextHeightBehavior = DefaultTextHeightBehavior.of(context);
See also:
- DefaultTextHeightBehavior.maybeOf, which is similar to this method, but asserts if no DefaultTextHeightBehavior ancestor is found.
Implementation
static TextHeightBehavior? maybeOf(BuildContext context) {
return context.dependOnInheritedWidgetOfExactType<DefaultTextHeightBehavior>()?.textHeightBehavior;
}
