pinnedColumnCount property

@override int pinnedColumnCount

The number of columns that are permanently shown on the leading vertical edge of the viewport.

If scrolling is enabled, other columns will scroll underneath the pinned columns.

Just like for regular columns, buildColumn method will be consulted for additional information about the pinned column. The indices of pinned columns start at zero and go to pinnedColumnCount - 1.

The integer returned by this getter must be smaller than (or equal to) the integer returned by columnCount.

If the value returned by this getter changes throughout the lifetime of the delegate object, notifyListeners must be called.

Implementation

@override
int get pinnedColumnCount => _pinnedColumnCount;

void pinnedColumnCount=(int value)

Implementation

set pinnedColumnCount(int value) {
  assert(value >= 0);
  assert(value <= columnCount);
  if (pinnedColumnCount == value) {
    return;
  }
  _pinnedColumnCount = value;
  notifyListeners();
}
