Case class Null safety
A block of CaseItems where only the one with a matching CaseItem.value is executed.
Searches for which of items appropriately matches expression, then executes the matching CaseItem. If defaultItem is specified, and no other item matches, then that one is executed. Use conditionalType to modify behavior in ways similar to what is available in SystemVerilog.

Case(Logic expression, List<
CaseItem> items, {List<Conditional> ? defaultItem, ConditionalType conditionalType = ConditionalType.none}) - Whenever an item in items matches expression, it will be executed.
Properties
- caseType → String
-
Returns the SystemVerilog keyword to represent this case block.
read-only
- conditionalType → ConditionalType
-
The type of case block this is, for special attributes
(e.g. ConditionalType.unique, ConditionalType.priority).
final
-
defaultItem
→ List<
Conditional> ? -
The default to execute when there was no match with any other CaseItems.
final
- expression → Logic
-
A logical signal to match against.
final
- hashCode → int
-
The hash code for this object.
read-onlyinherited
-
items
→ List<
CaseItem> -
An ordered collection of
CaseItems to search through for a match to expression.final - runtimeType → Type
-
A representation of the runtime type of the object.
