 In a large variety of languages `void` as return type is used to indicate that
 a function doesn't return anything. Dart allows returning `null` in functions
 with `void` return type but it also allow using `return;` without specifying any
-value. To have a consistant way you should not return `null` and only use an
+value. To have a consistent way you should not return `null` and only use an
 empty return.
