Uno Toolkit Statusbar Extensions

Uno Toolkit StatusBar Extensions — Agent Skill

Workflow

Docs lookup: call uno_platform_docs_search(...) first, then uno_platform_docs_fetch(sourcePath="…") using the sourcePath field from a result (a relative .md path; add the result's anchor for a section). Never pass a URL, a .html link, or a hand-built path.

Step 1: Fetch the StatusBar Extensions Documentation

uno_platform_docs_search("Uno Toolkit StatusBar extensions foreground background color iOS Android")

Primary documentation page:

• StatusBar Extensions: external/uno.toolkit.ui/doc/helpers/StatusBar-extensions.md

Fetch the page:

uno_platform_docs_fetch(sourcePath="external/uno.toolkit.ui/doc/helpers/StatusBar-extensions.md")

Critical Rules

• StatusBar.Foreground is a StatusBarForegroundTheme enum value, NOT a Brush. Use attribute syntax with a bare enum name: utu:StatusBar.Foreground="Light" (or Dark, Auto, AutoInverse). Element syntax or a Brush value (e.g. <utu:StatusBar.Foreground><SolidColorBrush Color="White"/></utu:StatusBar.Foreground>) is invalid.
• StatusBar.Background is a color/brush — accepts an attribute color name or a {StaticResource} brush.
• The class is StatusBar, not StatusBarExtensions, despite the file/skill name.

Key Principles (Stable)

• utu:StatusBar.Foreground — StatusBarForegroundTheme enum value
• utu:StatusBar.Background — color or brush
• StatusBarForegroundTheme values: Light (white icons), Dark (black icons), Auto (matches theme, updates on change), AutoInverse (opposite of theme, updates on change)
• Applied as attached properties on the Page element
• Works on iOS and Android only
• XAML namespace: xmlns:utu="using:Uno.Toolkit.UI"
