CaseZ class Null safety

A special version of Case which can do wildcard matching via z in the expression.

Any z in the value of a CaseItem will act as a wildcard.

Does not support SystemVerilog's ? syntax, which is exactly functionally equivalent to z syntax.

CaseZ(Logic expression, List<CaseItem> items, {List<Conditional>? defaultItem, ConditionalType conditionalType = ConditionalType.none}): Whenever an item in items matches expression, it will be executed, but the definition of matches allows for z to be a wildcard.

caseType → String: Returns the SystemVerilog keyword to represent this case block.

conditionalType → ConditionalType: The type of case block this is, for special attributes (e.g. ConditionalType.unique, ConditionalType.priority).

defaultItem → List<Conditional>?: The default to execute when there was no match with any other CaseItems.

expression → Logic: A logical signal to match against.

hashCode → int: The hash code for this object.

items → List<CaseItem>: An ordered collection of CaseItems to search through for a match to expression.
