material_navigation 0.1.0

Material 3 Expressive navigation for Flutter: a flexible navigation bar and a navigation rail that expands in place or as a modal, with spring motion.

0.1.0

Breaking.

• Migrates to material_ui.
• NavigationBarStyle and NavigationRailStyle are now ThemeExtensions with optional tokens, falling back to the Material 3 defaults for the current ColorScheme and TextTheme. Adds variant, of, merge and lerp.
• New tokens, including indicator shape, per-state icon and label styles, the rail's header and item spacing, item heights, groupAlignment and scrollable.
• Defaults follow the Material 3 tokens: the Expressive springs, an expanded rail sized to its destinations instead of a fixed 280dp, the rail's header and item spacing, onSurfaceVariant for disabled destinations, no shadow on the bar, and no bold active label in the baseline variant.
• Adds NavigationRail.groupAlignment, NavigationRail.modalMotion, NavigationMotion.defaultSpatial and NavigationMotion.fastSpatial.
• Destinations in a rail's trailing and expandedBody slots take the rail's layout and style instead of their own defaults.
• Removes itemVerticalSpace, and the style classes' besideLabelStart and destinationStyle getters.

0.0.2

• Fixes setState() or markNeedsBuild() called during build when a destination is selected, or the destinations change, while NavigationRail is open as a modal overlay. The overlay is now built with an OverlayPortal, so it also inherits what the rail inherits (such as a local Theme), and dialogs or routes opened while it is showing now appear above it instead of beneath it.
• Fixes NavigationBar throwing an ArgumentError and rendering no destinations when a destination is narrower than 80dp, for example five destinations on a screen under 400dp wide. Destinations now squash to fit.

0.0.1

• Initial release.
