PickerTabBar.secondary constructor

const PickerTabBar.secondary({ Key? key, required List<Widget> tabs, TabController? controller, bool isScrollable = false, EdgeInsetsGeometry? padding, Color? indicatorColor, bool automaticIndicatorColorAdjustment = true, double indicatorWeight = 2.0, EdgeInsetsGeometry indicatorPadding = EdgeInsets.zero, Decoration? indicator, TabBarIndicatorSize? indicatorSize, Color? dividerColor, Color? labelColor, TextStyle? labelStyle, EdgeInsetsGeometry? labelPadding, Color? unselectedLabelColor, TextStyle? unselectedLabelStyle, DragStartBehavior dragStartBehavior = DragStartBehavior.start, MaterialStateProperty<Color?>? overlayColor, MouseCursor? mouseCursor, bool? enableFeedback, ValueChanged<int>? onTap, ScrollPhysics? physics, InteractiveInkFeatureFactory? splashFactory, BorderRadius? splashBorderRadius, })

Creates a Material Design secondary tab bar.

Secondary tabs are used within a content area to further separate related content and establish hierarchy.

{@tool dartpad} This sample showcases nested Material 3 PickerTabBars. It consists of a primary PickerTabBar with nested a secondary PickerTabBar. The primary PickerTabBar uses a DefaultTabController while the secondary PickerTabBar uses a TabController.

** See code in examples/api/lib/material/tabs/tab_bar.2.dart ** {@end-tool}
