adaptive_foreground

Fixed

• Fixed broken relative demo.gif path in README.md by utilizing absolute raw GitHub URLs so that project visualizer media renders flawlessly on pub.dev.

Added

• AdaptiveNavBar widget — a pixel-perfect, pure-Flutter replica of the Apple App Store's adaptive frosted glass bottom navigation bar.
• CNSymbol and CNTabBar integrations from cupertino_native inside the example application to show authentic platform tab bars on iOS.
• Dynamic AdaptiveTheme resolving surface blurs, inactive elements tints, dynamic active highlight pills, and micro-thin top borders.
• Isolated, low-resolution pixel sampling in BrightnessSampler with debouncing (> 100ms) and smooth transitions (250ms curve).
• Dedicated widget and unit test coverage in test/adaptive_nav_bar_test.dart asserting correct rendering, taps, and theme color maps.

Fixed

• Relocated AppAdaptiveForeground context inside ColorPlaygroundPage using direct background color hint mapping, completely bypassing fragile screen captures and resolving Platform View compositing conflicts on iOS.
• Restored explicit tint: color on iOS native buttons to ensure native visual glass effects adapt dynamically to contrast state.
• Upgraded Android circular action buttons to implement high-performance BackdropFilter glassmorphism blurs and AnimatedContainer transitions matching iOS tab bar aesthetics.
• Custom-themed all example swiper pages and bottom tab items (Demo, Contrast, Glass, Metrics, Docs) to focus entirely on showcasing package features and guides.

Fixed

• Shortened pubspec.yaml description to satisfy the pub.dev 180-character limit.
• Added dartdoc comments to all public API fields (AppAdaptiveForeground, AppButtonIosAndroid, AppIosButton) to exceed the 20 % documentation threshold.

Added

• AppAdaptiveForeground widget — adaptive black/white foreground color based on background luminance, with smooth 300 ms ColorTween transitions.
• Hysteresis (hysteresis parameter, default 0.08) prevents status-bar icon oscillation when sampled luminance hovers near the switching threshold.
• Two sampling strategies: backgroundColorHint (instant) and live backdrop sampling via a RepaintBoundary samplingKey.
• updateStatusBar flag to keep SystemUiOverlayStyle in sync automatically.
• Static accessors: AppAdaptiveForeground.of, backgroundColorOf, systemStyleOf.
• AppButtonIosAndroid — cross-platform circular action button (native iOS CNButton on iOS, Material InkWell circle on Android).
• AppIosButton — thin wrapper over cupertino_native's CNButton.icon.
• AppDimensions — lightweight sizing constants (no external scaling library).
