rowCount property

  1. @override
int get rowCount
override

Called to obtain the number of rows to tell the user are available.

If isRowCountApproximate is false, then this must be an accurate number, and getRow must return a non-null value for all indices in the range 0 to one less than the row count.

If isRowCountApproximate is true, then the user will be allowed to attempt to display rows up to this rowCount, and the display will indicate that the count is approximate. The row count should therefore be greater than the actual number of rows if at all possible.

If the row count changes, call notifyListeners.

Implementation

@override
int get rowCount => _totalRows;
