Description

Schema::getDefault() today returns a null value if no default value is specified in the OpenAPI document. The OpenAPI standard allows to explicitly specify null when a property is nullable. However this case cannot be detected because Schema:getDefault() will return null in that situation, too. An additional boolean flag Schema::hasDefaultValue() would be required.

Use case is the OpenAPI generator, where I would like to generate special code if the default value is set explicitly to null.

Research direction

Start by locating Schema::getDefault() and the OpenAPI schema representation it reads. Add the requested Schema::hasDefaultValue() behavior so an omitted default is distinguishable from an explicitly specified null, allowing the OpenAPI generator to detect the explicit case.
