FdcGridRangeSelectionCellEditablePredicate typedef
Reports whether one grid cell may receive a range-paste update.
The grid host supplies this predicate and the range-selection session calls it
while validating a paste plan. Indexes are zero-based data-row and source-column
coordinates. Returning false excludes the cell from writable paste targets;
the session decides whether that makes the complete paste plan inapplicable.
This typedef is part of the stable fdc_ext.dart extension seam.
Implementation
typedef FdcGridRangeSelectionCellEditablePredicate =
bool Function(int rowIndex, int columnIndex);
