convert num to int dart code example

Example 1: dart string to int

main () {
// String -> int
    var one = int.parse('1');
    print(one == 1); // prints true
    
// String -> double
    var two = double.parse('10');
    print(two); //result is => 10.0
}

Example 2: convert from int64 to int dart

double d = 20.5;

int i = d.toInt(); // i = 20
int i = d.round(); // i = 21
int i = d.ceil();  // i = 21
int i = d.floor(); // i = 20
