instantiable property Null safety

bool instantiable
final

Whether the Built Value is instantiable. Defaults to true.

A non-instantiable Built Value has no constructor or factory. No implementation will be generated. But, an abstract builder will be generated, or you may write one yourself.

Other Built Values may choose to implement a non-instantiable Built Value, pulling in fields and methods from it. Their generated builders will automatically implement the corresponding builder, so you can access and modify the common inherited fields without knowing the concrete type.
