Issue with ColumnWidthMode.lastColumnFill in Flutter Syncfusion DataGrid for Single Row

I’m experiencing an issue with the SfDataGrid from the Syncfusion Flutter package, specifically when using the ColumnWidthMode.lastColumnFill setting. The problem occurs when there is only a single row in the grid.

With multiple rows, the grid behaves as expected: the columns adjust their widths based on the text in the cells, and the last column properly fills the remaining space. However, when there is only a single row, the lastColumnFill mode does not seem to work correctly. The column widths are not adjusted according to the text content in the cells, leading to improper alignment and spacing issues.

Here’s a summary of the behavior:

• With Multiple Rows: The grid columns adjust their width based on the
  content of the cells, and the last column fills the remaining width
  as intended.
• With Single Row: The column widths do not adjust according to the
  text content, and the last column does not fill the remaining space
  correctly.

I would appreciate any advice on how to address this issue or if there are any known workarounds. Has anyone encountered a similar problem, or does anyone have suggestions for ensuring that ColumnWidthMode.lastColumnFill works correctly even with a single row?
