createState method

@override _ThemeBuilderState 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
_ThemeBuilderState createState() => _ThemeBuilderState(
      ThemeManager(
        themes: themes,
        statusBarColorBuilder: statusBarColorBuilder,
        navigationBarColorBuilder: navigationBarColorBuilder,
        darkTheme: darkTheme,
        lightTheme: lightTheme,
        defaultTheme: defaultThemeMode,
      ),
    );
