Example (explore example code in the example app - it's short).
/// Example of ListDetailBase
class _MyHomePageState extends State<MyHomePage> {

/// Make a controller with the same type as your list.
/// [ColorEtymology] is an example data class
late final ListDetailController<ColorEtymology> controller;

@override
void initState() {
super.initState();
/// 5 second delay for show. Transform turns JSON list into a
/// list of your model
controller = ListDetailController(
fetch: () => Future.delayed(const Duration(seconds: 5), () => Future.value(colorMapList)),
transform: ColorEtymology.fromMap,
);
}

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text(widget.title)),
body: ListDetailLayout(
controller: controller,
listBuilder: (context, items, isSplitScreen) => ListView.builder(
itemCount: items.length,
// [Item] is an example view - a ListTile
itemBuilder: (context, index) => Item(
colorModel: items[index],
isSplitScreen: isSplitScreen,
onSelect: (value) => controller.select = value,
),
),
detailBuilder: (context, item, isSplitScreen) => item == null
? Container()
// [ColorModelDetail] is an example view - a Card
: ColorModelDetail(
colorModel: item,
isSplitScreen: isSplitScreen,
colorModelListenable: controller.selectedItem,
),
),
);
}
