DsBrandToggle class

A single-button brand toggle that flips between DsBrand.violet and DsBrand.emerald.

Violet (◆) ⇄ Emerald (🌿)

The icon swaps with the same rotate + scale + fade animation as DsThemeToggle. The icon color reflects the active brand's primary via colorScheme.primary, so the button is always in sync with the current theme.

───────────────────────────────────────────── Usage (StatefulWidget) ─────────────────────────────────────────────

class _RootState extends State<Root> {
  DsBrand _brand = DsBrand.violet;
  ThemeMode _mode = ThemeMode.system;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme:     _brand.lightTheme(),
      darkTheme: _brand.darkTheme(),
      themeMode: _mode,
      home: Scaffold(
        appBar: AppBar(
          actions: [
            DsBrandToggle(
              brand: _brand,
              onChanged: (b) => setState(() => _brand = b),
            ),
            const SizedBox(width: 8),
          ],
        ),
      ),
    );
  }
}

───────────────────────────────────────────── Usage with a ValueNotifier (no StatefulWidget needed) ─────────────────────────────────────────────

final brand = ValueNotifier(DsBrand.violet);

// In build:
ValueListenableBuilder<DsBrand>(
  valueListenable: brand,
  builder: (_, b, __) => DsBrandToggle(
    brand: b,
    onChanged: (next) => brand.value = next,
  ),
)
