padLeft abstract method

String padLeft(int width, [ String padding = ' ' ])

Pads this string on the left if it is shorter than width.

Return a new string that prepends padding onto this string one time for each position the length is less than width.

If width is already smaller than or equal to this.length, no padding is added. A negative width is treated as zero.

If padding has length different from 1, the result will not have length width. This may be useful for cases where the padding is a longer string representing a single character, like " " or "\u{10002}". In that case, the user should make sure that this.length is the correct measure of the strings length.
