Static Methods

availableCrossExtent({required double crossAxisSize, required EdgeInsets padding, required Axis axis}) → double

Cross-axis room left for item content after padding on axis.

buildItem({required M3EToolbarItem item, required double availableExtent, required Axis axis, required Widget buildAction(M3EToolbarAction action), double opticalInset = 0}) → Widget

Builds the visual for one item (icon button or constrained widget).

constrainWidget({required M3EToolbarWidget item, required double availableExtent, required Axis axis, double opticalInset = 0}) → Widget

Wraps a M3EToolbarWidget so it cannot exceed the bar content extent.

dockedGap({required double available, required double slotExtent, required int slotCount, required double preferredGap, required double minGap}) → double

Docked gap clamped to [minGap, preferredGap].

partitionInline({required List<M3EToolbarItem> items, required int maxInline, int? triggerIndex}) → ({List<M3EToolbarItem> inline, List<M3EToolbarAction> overflow})

Keeps all widgets inline; only excess non-trigger actions overflow.

reservedLabeledSelectionExtent({required List<M3EToolbarItem> inline, required Axis axis, required double iconVisualExtent, required double iconSlotExtent, required TextStyle labelStyle, required TextScaler textScaler, required double gap, required double labelGap, bool includeOverflowSlot = false}) → double?

Fixed pill width for labeled selection when the outer pill should not grow/shrink: widest (icon+label) action + icon-only neighbors + gaps.

withGaps(List<Widget> children, {required double gap, required Axis axis}) → List<Widget>

Inserts gap between consecutive children along axis.
