• forEach() expression.
• iterator property to get Iterator that allows iterating.
• every() method
• simple for-each loop
• for loop with item index

void main()
 {
var myList = [0, 'one', 'two', 'three', 'four', 'five'];
myList.forEach((item) => print(item));
 }

Output:

0

Iterator property to get Iterator that allows iterating:

void main()
 {
     var myList = [0, 'one', 'two', 'three', 'four', 'five'];
     var listIterator = myList.iterator;
     while (listIterator.moveNext()) {
     print(listIterator.current);
     }
 }

Output

 0
one
two
three
four
five

every() method:

 void main()
 {
     var myList = [0, 'one', 'two', 'three', 'four', 'five'];
     myList.every((item) {
     print(item);
     return true;
     });
 }

Output

0
one
two
three
four
five

simple for-each loop:

void main()
 {
     var myList = [0, 'one', 'two', 'three', 'four', 'five'];
     for (var item in myList) {
     print(item);
     }
 }

Output

0
one
two
three
four
five

for loop with item index:

void main()
 {
     var myList = [0, 'one', 'two', 'three', 'four', 'five'];
    for (var i = 0; i < myList.length; i++) {
    print(myList[i]);
     }
 }

Output
