Implementation

Simple implementation

SearchableList<Actor>(
  initialList: actors,
  builder: (Actor user) => UserItem(user: user),
  filter: (value) => actors.where((element) => element.name.toLowerCase().contains(value),).toList(),
  emptyWidget:  const EmptyView(),
  inputDecoration: InputDecoration(
    labelText: "Search Actor",
	fillColor: Colors.white,
	focusedBorder: OutlineInputBorder(
	  borderSide: const BorderSide(
	    color: Colors.blue,
		width: 1.0,
	  ),
	  borderRadius: BorderRadius.circular(10.0),
	),
  ),
),
