matchTypeByName static method

bool matchTypeByName(String? expectedType, TypeCode actualType, [ dynamic actualValue ])

Matches expected type to an actual type.

• expectedType an expected type name to match.
• actualType an actual type to match defined by type code.
• actualValue an optional value to match its type to the expected one. Returns true if types are matching and false if they don't.
