didExceedMaxLines property

bool didExceedMaxLines

Whether any text was truncated or ellipsized.

If maxLines is not null, this is true if there were more lines to be drawn than the given maxLines, and thus at least one line was omitted in the output; otherwise it is false.

If maxLines is null, this is true if ellipsis is not the empty string and there was a line that overflowed the maxWidth argument passed to layout; otherwise it is false.

Valid only after layout has been called.

Implementation 

bool get didExceedMaxLines {
  assert(!_needsLayout);
  return _paragraph.didExceedMaxLines;
}
