createState method
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() {
return SoundPlayerUIState(
_track,
_onLoad,
enabled: _enabled,
backgroundColor:
(_backgroundColor != null) ? _backgroundColor : Color(0xFFFAF0E6),
iconColor: _iconColor,
disabledIconColor: _disabledIconColor,
textStyle: _textStyle,
titleStyle: _titleStyle,
sliderThemeData: _sliderThemeData,
);
}
