FTabs constructor

FTabs({ required List<FTabEntry> children, bool scrollable = false, ScrollPhysics? physics, FTabController? controller, FTabsStyle style(FTabsStyle)?, ValueChanged<int>? onChange, ValueChanged<int>? onPress, int initialIndex = 0, Key? key, })

Creates a FTabs.

Contract

Throws AssertionError if:

• children is empty.
• initialIndex is not within the range '0 <= initialIndex < tabs.length`.
• controller index does not match the initialIndex.

Implementation

FTabs({
  required this.children,
  this.scrollable = false,
  this.physics,
  this.controller,
  this.style,
  this.onChange,
  this.onPress,
  this.initialIndex = 0,
  super.key,
}) : assert(children.isNotEmpty, 'Must provide at least 1 tab.'),
     assert(
       0 <= initialIndex && initialIndex < children.length,
       'initialIndex ($initialIndex) must be between 0 and the number of children (${children.length})',
     ),
     assert(
       controller == null || initialIndex == 0,
       'Cannot provide both controller and initialIndex. To fix, set the initialIndex on the controller.',
     ),
     assert(
       controller == null || controller.length == children.length,
       "Controller's number of tabs (${controller.length} must match the number of children (${children.length}).",
     );
