changeTheme static method

void changeTheme({ @Deprecated('No longer needed; the theme can be changed without a BuildContext.') BuildContext? context, required String themeKey, })

Switches the whole app to the theme registered under themeKey and persists it.

The current page stays on screen; every widget reading the theme rebuilds with the new one.

Throws AppThemeException if themeKey is unknown or init has not completed.

Implementation

static void changeTheme({
  @Deprecated('No longer needed; the theme can be changed without a BuildContext.') BuildContext? context,
  required String themeKey,
}) {
  final bloc = _requireBloc();
  final theme = _findTheme(themeKey);
  if (theme == null) {
    throw AppThemeException('${ThemeExceptionConstants.notFoundKey} Key: "$themeKey".');
  }
  bloc.add(AppThemeEvent.changeTheme(theme));
}
