CustomSelector class

A customizable selector widget that fetches items from a Future and allows selection.

Example usage with defaultItem:

CustomSelector(
  future: apiService.getCategories(),
  label: 'Select Category',
  itemDisplayProperty: (item) => item.name,
  defaultItem: selectedCategory, // Pre-select an item
  onSelect: (item) {
    setState(() {
      selectedCategory = item;
    });
  },
)
