createState method

@override State<StatefulWidget> createState()

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<StatefulWidget> createState() => new AutoCompleteTextFieldState<String>(
        suggestions,
        textChanged,
        textSubmitted,
        onFocusChanged,
        itemSubmitted, (context, item) {
      return new Padding(padding: EdgeInsets.all(8.0), child: new Text(item));
    }, (a, b) {
      return a.compareTo(b);
    }, (item, query) {
      return item.toLowerCase().startsWith(query.toLowerCase());
    },
        suggestionsAmount,
        submitOnSuggestionTap,
        clearOnSubmit,
        minLength,
        [],
        textCapitalization,
        decoration,
        style,
        keyboardType,
        textInputAction,
        controller,
        focusNode);
