I am building a two dimensional TableView in my Flutter app to display a type of spreadsheet.
In this view I want to be able to drag cells to a new position, including to cells not within the current display area.
For example, I have a cell at column 3, row 2 in a display showing 5 x 5 cells.
I want to drag the cell to a cell in row 6, which is currently not displayed.
Is there a way to force the TableView to scroll down as I drag the cell off the bottom edge?
