maybeOf static method
- BuildContext context
Returns the ScrollController most closely associated with the given context.
Returns null if there is no ScrollController associated with the given context.
Calling this method will create a dependency on the closest
PrimaryScrollController in the context, if there is one.
See also:
- PrimaryScrollController.maybeOf, which is similar to this method, but asserts if no PrimaryScrollController ancestor is found.
Implementation
static ScrollController? maybeOf(BuildContext context) {
final PrimaryScrollController? result = context.dependOnInheritedWidgetOfExactType<PrimaryScrollController>();
return result?.controller;
}
