Added Feature: Hide Filter Bar

Description

This PR introduces a new feature to allow dynamic control over the visibility of the filter bar in the PagedDataTable widget.

New Property:

• hideFilterBar:
  • A bool property added to the PagedDataTableThemeData class.
  • Default value: false, ensuring backward compatibility.

Usage:

• When hideFilterBar is set to true, the filter bar will not be rendered.
• When hideFilterBar is false (default), the filter bar will remain visible.

Changes Made:

1. Added hideFilterBar to PagedDataTableThemeData.
2. Updated PagedDataTable to respect the hideFilterBar property when building the widget tree.

Motivation

This enhancement provides developers with the flexibility to hide the filter bar when it is not needed, improving the customization options for the PagedDataTable widget.

Testing

• Verified that the filter bar is hidden when hideFilterBar is set to true.
• Confirmed that the filter bar remains visible by default when hideFilterBar is not specified or set to false.
