What ways in Dart can you check if a string reads the same from left to right and right to left?

In Dart, you can check if a string is a palindrome (reads the same forwards and backwards) in several ways:

1. Compare the string with its reversed copy:

bool isPalindrome(String s) {
  String reversed = s.split('').reversed.join('');
  return s == reversed;
}

2. Use two pointers — one at the start and one at the end, comparing characters alternately:

bool isPalindrome(String s) {
  int left = 0;
  int right = s.length - 1;
  while (left < right) {
    if (s[left] != s[right]) return false;
    left++;
    right--;
  }
  return true;
}

Both methods are effective for palindrome checking.
