# createState method Null safety

1. @override

State<MyDividerForm> createState()
override

Creates the mutable state for this widget at a given location in the tree.

Subclasses should override this method to return a newly created instance of their associated State subclass:

    @override
    State<SomeWidget> createState() => _SomeWidgetState();

The framework can call this method multiple times over the lifetime of a `StatefulWidget`. For example, if the widget is inserted into the tree in multiple locations, the framework will create a separate State object for each location. Similarly, if the widget is removed from the tree and later inserted into the tree again, the framework will call createState again to create a fresh State object, simplifying the lifecycle of State objects.

## Implementation

    @override
    State<MyDividerForm> createState() => _MyDividerFormState(formAction);
