list in dart
main(List<String> args) {
//Syntax : List<ValuesDataType> ListName = [Values]
List<int> x = [10, 20, 30, 50, 70, 90];
//? printing specific value : print (ListNameHere[ItsArrangeStartFrom0]);
//! example
print(x[0]);
//? printing the whole list : print (ListName)
print(x);
//? calculate list values :
//! example
print(x[0] * x[5]);
//? to add a new value to the list use <ListName>.add(Value);
//! example
x.add(155);
}create a int list dart
// a simple a.to(b) solution:
extension RangeExtension on int {
List<int> to(int maxInclusive) =>
[for (int i = this; i <= maxInclusive; i++) i];
}
// or with optional step:
extension RangeExtension on int {
List<int> to(int maxInclusive, {int step = 1}) =>
[for (int i = this; i <= maxInclusive; i += step) i];
}
// use the last one like this:
void main() {
// [5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38, 41, 44, 47, 50]
print(5.to(50, step: 3));
