ellipsSize method

String ellipsSize({ required int maxLength, bool fromStart = false, })

ellipsSize Returns a new string truncated to the specified maximum length.

If the string is longer than the maxLength, it is truncated and an ellipsis is appended. If the string is shorter than or equal to the maxLength, it is returned unchanged.

The fromStart parameter determines whether the truncation occurs from the start or end of the string. If fromStart is true, the truncation occurs from the start of the string, and the ellipsis is prepended. If fromStart is false (default), the truncation occurs from the end of the string, and the ellipsis is appended.

Example:

String text = "This is a very long string";
String truncatedText = text.ellipsSize(maxLength: 10);
print(truncatedText); // "This is a..."

String truncatedTextFromStart = text.ellipsSize(maxLength: 10, fromStart: true);
print(truncatedTextFromStart); // "...very long string"

Implementation

String ellipsSize({required int maxLength, bool fromStart = false}) {
  if (length > maxLength) {
    if (fromStart) {
      return "...${substring(length - maxLength)}";
    }
    return "${substring(0, maxLength)}...";
  } else {
    return this;
  }
}
