OudsThemeTweak class

Modifies the current OUDS theme configuration and applies it to the given child.

This widget allows you to temporarily override the theme mode for a specific subtree without affecting the rest of your application. It's useful for:

Preview/demo screens showing both light and dark themes side-by-side
Specific UI sections that need forced light/dark mode (e.g., video player always dark)
Theme switching animations or transitions
Component showcases in design systems

Important Notes:

This widget must be nested within an OudsTheme widget
Multiple OudsThemeTweak widgets can be nested (inner tweak takes precedence)
The tweak only affects the visual appearance; logical theme queries via OudsTheme.modeOf will reflect the tweaked mode within the subtree
Use OudsTheme.isOudsInDarkTheme to check the effective theme mode (respects tweaks)

tweak: The specific adjustment to apply: ( OudsThemeTweakType.invert, OudsThemeTweakType.forceDark, or OudsThemeTweakType.forceLight)
child: The widget subtree to which the tweaked theme will be applied. This widget receives a context with the tweaked theme.

Accessing the tweaked theme:

OudsThemeTweak(
  tweak: OudsThemeTweakType.invert,
  child: MyComponentPreview(),
  ),
)

Force Light theme preview:

OudsThemeTweak(
  tweak: OudsThemeTweakType.forceLight,
  child: MyComponentPreview(),
),

Force Dark theme preview:

OudsThemeTweak(
  tweak: OudsThemeTweakType.forceDark,
  child: MyComponentPreview(),
),
