MultipleSearchSelection<T>.creatable

MultipleSearchSelection<T>.creatable constructor can now create new item when search result does not return any results. It takes a new required parameter, createOptions e.g :

// [T] here is [Country]
createOptions: CreateOptions<Country>(
    // You need to create and return the item you want to add since [T] is not always [String].
    create: (text) {
        return Country(name: text, iso: text);
    },
    // A callback when the item is succesfully created.
    onCreated: (c) => print('Country ${c.name} created'),
    // Create item Widget that appears instead of no results.
    createBuilder: (text) => Align(
        alignment: Alignment.centerLeft,
            child: Padding(
                padding: const EdgeInsets.all(8.0),
                child: Text('Create "$text"'),
            ),
        ),
    // Whether you want to pick the newly created item or just add it to your list. Defaults to false.
    pickCreated: true,
),
