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 TextFieldAutoCompleteState<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);
