Trait is only documented here

symfony-docs/components/type_info.rst

Lines 29 to 41 in 8801059

	There are two ways to use this component. First one is to create a type manually thanks
	to the :class:`Symfony\\Component\\TypeInfo\\Type` static methods as following::
	use Symfony\Component\TypeInfo\Type;
	Type::int();
	Type::nullable(Type::string());
	Type::generic(Type::object(Collection::class), Type::int());
	Type::list(Type::bool());
	Type::intersection(Type::object(\Stringable::class), Type::object(\Iterator::class));
	// Many others are available and can be
	// found in Symfony\Component\TypeInfo\TypeFactoryTrait

All methods are not listed.

@mtarld You think we must add one or multiple example for fromValue method ? Or not

(I can make PR)

@alamirault, yes I think that we can provide one example of the fromValue 🙂

But I'm not sure that more than one example is useful here.
