How do you use a switch case in darts?

switch( expression ) { case value-1: Block-1; Break; case value-2: Block-2; Break; case value-n: Block-n; Break; default: Block-1; Break; } Statement-x; The expression can be integer expression or a character expression . Value-1, 2, n are case labels which are used to identify each case individually.

The main reasons for using a switch include improving clarity , by reducing otherwise repetitive coding, and (if the heuristics permit) also offering the potential for faster execution through easier compiler optimization in many cases.
