lineCount property

Implementation

@override
int get lineCount {
  var count = 0;
  if (_borderTop) count++;
  if (_borderBottom) count++;
  if (_headers.isNotEmpty) count++; // Header row
  if (_borderHeader && _headers.isNotEmpty) count++; // Header separator

  final startRow = _offset.clamp(0, _rows.length);
  var visibleRows = _rows.length - startRow;
  if (_height != null) {
    var usedLines = count;
    final availableRows = _height! - usedLines;
    if (availableRows > 0 && availableRows < visibleRows) {
      visibleRows = availableRows;
    }
  }
  count += visibleRows;
  if (_borderRow && visibleRows > 1) {
    count += visibleRows - 1; // Row separators
  }
  return count;
}
