GlassToolbar class
A glass morphism toolbar following Apple's iOS 26 design patterns.
GlassToolbar provides a sophisticated bottom toolbar for actions, utilizing the liquid glass material. It is typically used at the bottom of the screen to present a set of actions relevant to the current context.
Unlike GlassTabBar.bottom which is for navigation, GlassToolbar is for actions (e.g., "Edit", "Share", "Delete").
Key Features
- Liquid Glass Material: Translucent, blurring background that floats over content.
- Flexible Layout: Supports any children, typically GlassButtons.
- Customizable: Control height, alignment, and glass settings.
- iOS 26 Compliance: Matches the visual style of system toolbars.
