Dart vs Kotlin: numbers

numbers.dart

void main() {
  int intNumber = 10;
  double doubleNumber = 70.0;
  double exponentialNumber = 1.35e2;
  int hexadecimalNumber = 0xF1A;
  double castIntToDouble = intNumber.toDouble();
  int castDoubleToInt = doubleNumber.toInt();
  var intString = intNumber.toString();
  int? parsedNumber = int.tryParse("16");
}

numbers.kt

    var intNumber: Int = 10

    var exponentialNumber: Double = 1.35e2
    var hexadecimalNumber: Int = 0xF1A
    var castIntToDouble = intNumber.toDouble()
    var castDoubleToInt = doubleNumber.toInt()
