How to mesure the duration taken from a block of code in the dart-CodePudding

I have as an example this block of code :

for(int index = 0; index < 1000000; index =1) {
 print(i);
}

is there any way to measure the time/duration taken by this to finish in the milliseconds

without using external source, I mean any idea to do it in the dart ?

CodePudding user response：

You can use the Stopwatch class which makes it easy to measure time:

void main() {
  Stopwatch stopWatch = Stopwatch()..start();

  for(int index = 0; index < 1000000; index =1) {
    print(index);
  }

  print('Time it took: ${stopWatch.elapsedMilliseconds}ms');
}
