createState method
CurrencySelectorState<CurrencySelector<CurrencySelectorItem> , CurrencySelectorItem>
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
// ignore: no_logic_in_create_state
CurrencySelectorState createState() => switch (searchType) {
CurrencySelectorType.searchAnchorBar =>
CurrencySelectorBarState<CurrencySelector, K>(),
CurrencySelectorType.searchAnchorMin =>
CurrencySelectorMinState<CurrencySelector, K>(),
_ => CurrencySelectorState<CurrencySelector, K>(),
};
