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;
}
