dropUntil method Null safety

bool dropUntil(
  1. Characters target
)

Drops characters from the start of the range until before the first occurrence of target.

If the range contains any occurrences of target, then all characters before the start of the first such occurrence is removed from the range. This advances the start of the range to the start of the first occurrence of target.

If there are no occurrences of target in the range, all characteres in the range are removed, which gives the same effect as collapseToEnd.

Returns true if there is an occurrence of target and false if not.

Implementation

bool dropUntil(Characters target);
