maybeOf static method
- BuildContext context
The state from the closest instance of this class that encloses the given context.
This method is typically used by AnimatedGrid item widgets that insert or remove items in response to user input.
If no AnimatedGrid surrounds the context given, then this function will return null.
This method can be expensive (it walks the element tree).
This method does not create a dependency, and so will not cause rebuilding when the state changes.
See also:
- of, a similar function that will throw if no AnimatedGrid ancestor is found.
Implementation
static AnimatedGridState? maybeOf(BuildContext context) {
return context.findAncestorStateOfType<AnimatedGridState>();
