Create Items

for creating items you can use primary constructor or builder named constructor.

1. Primary constructor:

BreadCrumb(
	items: <BreadCrumbItem>[
		 BreadCrumbItem(content: Text('Item1')),
		 BreadCrumbItem(content: Text('Item2')),
								 ...
	],
	divider: Icon(Icons.chevron_right),
)

2. Builder named constructor:

BreadCrumb.builder(
	itemCount: 8,
	builder: (index) {
		return BreadCrumbItem(content: Text('Item$index'));
	},
	divider: Icon(Icons.chevron_right),
)

Care about Overflow

select a right overflow behavior for your BreadCrumb widget.

1. WrapOverflow behavior: you can use this behavior when you want to your widget, wrap whenever it uses all of the main Side sizes:

BreadCrumb(
	items: <BreadCrumbItem>[
		//add your BreadCrumbItem here
	],
	divider: Icon(Icons.chevron_right),
	overflow: WrapOverflow(
		keepLastDivider: false,
		direction: Axis.horizontal,
	),
)

2. ScrollableOverflow behavior: use it whenever you want to content your widget scroll if it needed.

BreadCrumb(
	items: <BreadCrumbItem>[
		//add your BreadCrumbItem here
	],
	divider: Icon(Icons.chevron_right),
	overflow: ScrollableOverflow(
		keepLastDivider: false,
		reverse: false,
		direction: Axis.horizontal,
	),
)

3. Custom Overflow behavior: you can easily create your own overflow behavior. the only thing you need is to create a class and extends it from the BreadCrumbOverflow class and overwrite its dependencies.

class CustomOverflowBehavior extends BreadCrumbOverflow{
	@override
	Widget build(BuildContext context, List<BreadCrumbItem> items, Widget divider) {
		// TODO: implement build
	}

	@override
	// TODO: implement keepLastDivider
	bool get keepLastDivider => _keepLastDivider;

	@override
	List<Widget> widgetItems(List<BreadCrumbItem> items, Widget divider) {
		// TODO: implement widgetItems
	}
}

* override widgetItems method to create List<Widget> with items and divider parameters.

* override build method to create your own widget behavior. for example wrap behavior uses Wrap widget. and you can use widgetItems method in your build method to create List<Widget> items.
