Use modulo for the most efficient implementation:

int x = 1993;
List<int> xList = [];

while(x > 0) {
    xList.add(x % 10);
    x = x ~/ 10;
}
xList = xList.reversed.toList();

print(xList);

This method takes the modulo 10 of the number to get the ones digit and adds it to a list. It then divides by 10 to shift the digits to the right. Since the digits were added in the reverse order of what you want, the list is reversed at the end.

Try This simple method :

int x = 123456
var data = x.toString().split('');
print(data);

Try this:

int yourNumber = 1234;
final yourInts = yourNumber.toString().split('').map((element) => int.parse(element)).toList();
print(yourInts);
