better_data_table

New features:

• BetterDataTable.expandedRowChildBuilder — a new expansion builder whose content renders as its own full-width block between rows instead of being placed inside the expand column's table cell like expandableRowBuilder. Falls back to expandableRowBuilder for a row when it returns null, so both builders can be mixed on the same table. Table borders/dividers won't draw through this content since it sits outside the Table widget.

Fixed:

• Expand icon displays at true size — the expand toggle cell no longer applies cellPadding to its container, which was shrinking the available space in the fixed-width (48 px) column and clipping larger custom icons
• Custom expand icons rendered without extra padding — the inner Padding(EdgeInsets.all(4)) now wraps only the default fallback icons; widgets supplied via BetterDataTableTheme.rowExpandIcon / rowCollapseIcon are rendered as-is

New features:

• Pointer cursor on clickable rows — rows with any tap handler (onRowTap, onRowDoubleTap, onRowLongPress, onRowSecondaryTap, BetterDataTableRow.onTap) automatically show SystemMouseCursors.click on desktop and web
• Fully customizable icons — six new Widget? fields on BetterDataTableTheme let you replace every icon with any widget:
  • sortAscendingIcon / sortDescendingIcon — sort direction indicators in column headers
  • rowExpandIcon / rowCollapseIcon — expand/collapse toggle on hierarchical and expandable rows
  • groupExpandIcon / groupCollapseIcon — chevron in collapsible group headers
• No empty box for non-expandable rows — when the expand column is present but a row has no children and no expandable content, the cell now renders as SizedBox.shrink() instead of a padded empty container

Initial public release.

New features:

• BetterDataTableColumn.visible — hide/show individual columns at runtime
• BetterDataTableColumn.tooltip — tooltip on column header
• BetterDataTableColumn.minWidth / maxWidth — now actually enforced via MaxColumnWidth / MinColumnWidth wrappers
• BetterDataTableColumn.copyWith()
• BetterDataTableRow.tooltip — tooltip on hover over entire row
• BetterDataTableRow.copyWith()
• BetterDataTableGroup.collapsible — users can collapse/expand groups; controlled via BetterDataTable.collapsedGroups + onGroupToggled
• BetterDataTableGroup.copyWith()
• BetterDataTable.onRowSecondaryTap — right-click / secondary tap callback
• BetterDataTable.rowDivider (BorderSide?) — full-width row divider drawn as a bottom border on each data row (replaces the broken single-cell divider)
• BetterDataTable.collapsedGroups + BetterDataTable.onGroupToggled

Fixed:

• BetterDataTableTheme.striped now actually applies alternating row colors
• alternateRowDecoration is now used for odd-indexed rows
• cellTextStyle is now applied to every data cell via DefaultTextStyle.merge
• minWidth / maxWidth on columns were defined but had no effect — fixed
• Expand toggle now has a circular InkWell splash for better touch feedback

Structural:

• Split into lib/src/ modules (better_data_table_column.dart, better_data_table_row.dart, better_data_table_group.dart, better_data_table_theme.dart, better_data_table_widget.dart) with a clean barrel export in lib/better_data_table.dart
• 46 widget and unit tests added
