Instance member 'readLineSync' can't be accessed using static

I'm trying to make a BMI calculator as a beginner project, as I am learning Dart. However, when I'm trying to take input, it outputs an error

import 'dart:io';

void main() {

  print('What is your weight in kgs?');
  var weight = Stdin.readLineSync();

  print("Your weight is $weight");


}

enter image description here

You're trying to call readLineSync on the class, not on an instance. Since readLineSync isn't static, you'll need to call this on an instance of Stdin.

There's a global instance of Stdin named stdin exposed through dart:io that you can use for this.
