GlassSegmentedControl constructor

const GlassSegmentedControl({ required List<GlassSegment> segments, required int selectedIndex, required ValueChanged<int> onSegmentSelected, Key? key, double height = GlassDefaults.heightControl, double borderRadius = GlassDefaults.borderRadius, EdgeInsetsGeometry padding = const EdgeInsets.all(2), TextStyle? selectedTextStyle, TextStyle? unselectedTextStyle, Color? backgroundColor, Color? indicatorColor, LiquidGlassSettings? indicatorSettings, double indicatorPinchStrength = 0.4, EdgeInsetsGeometry indicatorExpansion = const EdgeInsets.symmetric(horizontal: 12, vertical: 8), LiquidGlassSettings? settings, bool useOwnLayer = false, GlassQuality? quality, GlobalKey<State<StatefulWidget>>? backgroundKey, GlassInteractionBehavior interactionBehavior = GlassInteractionBehavior.full, Color? glowColor, double glowRadius = 1.5, bool isScrollable = false, double iconSize = 24.0, EdgeInsetsGeometry labelPadding = const EdgeInsets.symmetric(horizontal: 16), Color? selectedIconColor, Color? unselectedIconColor, MaskingQuality maskingQuality = MaskingQuality.high, DividerSettings? dividerSettings, List<BoxShadow>? indicatorShadow, })

Creates a fixed-width glass segmented control (iOS UISegmentedControl).

All segments are equal-width. For a scrollable variant that mimics GlassTabBar(isScrollable: true), use GlassSegmentedControl.scrollable.

Implementation

const GlassSegmentedControl({
  required this.segments,
  required this.selectedIndex,
  required this.onSegmentSelected,
  super.key,
  this.height = GlassDefaults.heightControl,
  this.borderRadius = GlassDefaults.borderRadius,
  this.padding = const EdgeInsets.all(2),
  this.selectedTextStyle,
  this.unselectedTextStyle,
  this.backgroundColor,
  this.indicatorColor,
  this.indicatorSettings,
  this.indicatorPinchStrength = 0.4,
  this.indicatorExpansion =
      const EdgeInsets.symmetric(horizontal: 12, vertical: 8),
  this.settings,
  this.useOwnLayer = false,
  this.quality,
  this.backgroundKey,
  // ── iOS 26 interaction ──────────────────────────────────────────────────
  this.interactionBehavior = GlassInteractionBehavior.full,
  this.glowColor,
  this.glowRadius = 1.5,
  // Scrollable-mode fields — unused in fixed mode.
  this.isScrollable = false,
  this.iconSize = 24.0,
  this.labelPadding = const EdgeInsets.symmetric(horizontal: 16),
  this.selectedIconColor,
  this.unselectedIconColor,
  this.maskingQuality = MaskingQuality.high,
  this.dividerSettings,
  this.indicatorShadow,
})  : assert(
        segments.length >= 2,
        'GlassSegmentedControl requires at least 2 segments',
      ),
      assert(
        segments.length <= 6,
        'GlassSegmentedControl works best with 2–5 segments. '
        'For 6+ items use GlassSegmentedControl.scrollable().',
      ),
      assert(
        selectedIndex >= 0 && selectedIndex < segments.length,
        'selectedIndex must be within bounds of segments list',
      );
