toString method

  1. @override
String toString()
override

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  if (left == 0 && top == 0 && right == 0 && bottom == 0) {
    return 'Spacing.none';
  }
  if (left == right && top == bottom) {
    if (left == top) {
      return 'Spacing.all($left)';
    }
    if (left == 0 && top == 0) {
      return 'Spacing.none';
    }
    if (left == 0) {
      return 'Spacing.vertical($top)';
    }
    if (top == 0) {
      return 'Spacing.horizontal($left)';
    }
    return 'Spacing.symmetric(vertical: $top, horizontal: $left)';
  }
  return 'Spacing.fromLTRB($left, $top, $right, $bottom)';
}
