플러터 Flutter For문 Switch문 간단 구현

• For문

for (int i = 0; i < 10; i++) {
  print("현재 값은 $i");
}

 

• Switch문

int grade = 80;

switch (grade) {
  case 90:
    print("Grade is A");
    break;
  case 80:
    print("Grade is B");
    break;
  case 70:
    print("Grade is C");
    break;
  default:
    print("Grade is not A, B, or C");
    break;
}
