Overview
The switch statement is a conditional statement similar to if-else
. It has different case clauses specified by the case
keyword which are similar to conditions in an if-else
statement. switch
takes an expression and the case clause which is equivalent to that expression will be executed.
switch
differs from if-else
in the fact that if
statements can only return true
or false
, and can only be defined as such. Case clauses, on the other hand, are not restricted to boolean values (integers, strings, or compile-time constants). However, make sure the case clauses have the same type as the expression.
Switch statements in Dart are intended for limited circumstances, such as in interpreters or scanners.
