showing horizontal scroll bar flutter

Question

I want to always show the scroll bar below the datatable for the web version. But it's showing this error message:

The Scrollbar's ScrollController has no ScrollPosition attached.

and the scroll bar doesn't work.

Scrollbar(
  isAlwaysShown: true,
  controller: ScrollController(),
  thickness: 10,
  child: PaginatedDataTable(
      showCheckboxColumn: false,
      columns: generateColumns(),
      source: generateDataSources(),
      rowsPerPage: count.toInt()),
);

Answer 1

Well try to remove the controller then ? controller: ScrollController()

Answer 2

Just remove the line :

controller: ScrollController(),

and the exception should be cleared. That is how I fixed mine.
