void main(){
  List magicSquare = [
    [2, 7, 6],
    [9, 5, 1],
    [4, 3, 8],
];

List checkingMagicFuncs = [
  coloumnChecker(magicSquare),
  rowChecker(magicSquare),
  rightDiagonalChecker(magicSquare),
  leftDiagonalChecker(magicSquare),
  ];


functionChecker(checkingMagicFuncs);

}

basically all i need is someone to review my code :
also im thinking of creating one function named diagonalChecker and take either "left" or "right" as arg instead of creating two functions rightDiagonalChecker and leftDiagonalChecker to reduce redundancy maybe?

Comments:

• Line 25 and line 32, why are you comparing a boolean to true or false?
• The loop in line 24 could be a bit more concise, bool functionIsTrue = functions.any((x) => x);
• The entire function in line 41 could probably be refactored to listOfNumbers.fold(0, (p, c) => p + c);
• rowChecker could be simplified to return magicSquare.all((row) => sum(row) == 15);, same thing kind of applies to the coloumnChecker (also it's spelled column)

can i ask u a question i really want to understand this

final numbers = <int>[1, 2, 3, 5, 6, 7];
var result = numbers.any((element) => element >= 5); // true;
result = numbers.any((element) => element >= 10); // false;

What does this code do like from my understanding all it do is like checks if any element is 5 it returns true
but what i dont understand is what does >= mean is it greater than or equal to?

oh i think i got it

  bool a = true, b = false, c = true;
  List bools = [a, b, c];


  print(bools.any((element) => b));

it js checks whether the given element is in the list or not

nvm then

but theres still gonna be more questions i hope i can do them on my own if not then not rob

[indigo widget]

but no

i dont get it

what does >= mean
