flutter_table_layout 0.1.3

Responsive data table for Flutter with frozen columns, sorting, filtering, grouping, editing, and Excel/PDF export for mobile, web, and desktop.

Changelog

0.1.3

Fixes

• Date panel popped the page underneath (web / wide screens): pressing Apply in the date range panel closed it with the caller's Navigator, not the dialog's. With go_router's ShellRoute (a nested navigator under the root one that hosts the dialog) this popped the current page instead, throwing "You have popped the last page off of the stack" followed by !_debugLocked errors. The panel now closes through its own route context. Covered by a regression test with a nested navigator.

0.1.2

Release automation

• Versions are now published to pub.dev automatically from GitHub Actions when a v{{version}} tag is pushed.

Fixes

• Column resize in RTL felt inverted: grid rows were anchored to the left in right-to-left layouts, so widening a column moved the opposite edge. Rows now start at the right in RTL.
• Resize edge didn't follow the pointer: flexible columns before the resized one absorbed the change. They are now frozen during the drag; only the columns after it adapt. Covered by 8 tests (LTR/RTL × fixed/flex × grow/shrink).

Date filter redesign (new)

• The two From / To buttons (each opening the same full calendar) are replaced by a single "Period" button. It opens a panel with quick periods (all, today, yesterday, last 7 / 30 days, this / last month, this year), a two-month range calendar and typed From / To fields. On phones it opens as a bottom sheet.
• datePresets / DateRangePreset for custom periods, showTableDateRangePicker / DateRangePanel for standalone use.
• dateFilterStyle: DateFilterStyle.separateFields keeps the previous look.

0.1.1

• Fixes and improvements.

0.1.0

A full audit and overhaul. The public API is backward compatible: existing code keeps compiling, and the original tests pass unchanged.

Bug fixes

• Date filter: clearing a date (✕) did nothing because copyWith couldn't reset nullable fields. TableStateModel.copyWith now has clearStartDate / clearEndDate / clearSort.
• Columns menu: toggling a column threw ProviderNotFoundException (the popup lives outside the BlocProvider), and its checkboxes didn't update.
• Web export: nothing was downloaded (the download code was commented out). Rewritten with package:web.
• showPagination: false: only the first 10 rows were ever shown.
• pageSizes without 10: the rows-per-page dropdown crashed.
• Data updates: changing the items list in place (add / remove followed by setState) did not refresh the table.
• TableCubit mutated the caller's column list, and crashed when given a const list.
• Exports: columns hidden by the user were still exported.
• Word export: values were not HTML-escaped, so <, & or quotes broke the document.
• Excel export: invalid sheet names (/, :, more than 31 characters) produced corrupted files. Also fixed the fragile default-sheet deletion.
• RTL: pagination arrows were flipped twice, and column alignment ignored RTL.
• Sorting: crashed on mixed value types, was case-sensitive, not stable, and placed nulls inconsistently.
• Pagination: the current page was not clamped after filtering or deleting (it showed "No data" while data existed), and an empty table showed "Page 1 of 0".
• Filters: the date pickers were shown even without a dateProvider. The picker crashed when initialDate was outside 2000–2100.
• Row details: expandedRowBuilder only opened for selected rows (impossible when showSelection: false), and onRowTap was ignored on mobile.
• Footer: the page numbers could overflow on phones when there were many pages.
• Toolbar: it overflowed on narrow screens, and snackbars used a BuildContext across async gaps.
• Theme: the default theme was always light, even in dark apps. Many colors were hard-coded blue.
• Dynamic form:
  • any name containing "is" (discount, wishlist…) was detected as a boolean;
  • a required dropdown displayed its first item but submitted null;
  • an invalid dropdown initial value crashed;
  • the date field ignored isRequired;
  • custom validators only ran for text fields;
  • the internal mutable map was leaked to callers.
• Removed dead placeholder code in FilterItemsUseCase.execute, which now works and sorts.
• Fixed every analyzer deprecation (withOpacity, dart:html, Share.shareXFiles, DropdownButtonFormField.value, Switch.activeColor).

Advanced grid (new)

• Frozen columns: pin: ColumnPin.start / end, pin/unpin from the columns menu, LTR and RTL. Implemented with a custom RenderPinnedRow.
• Sticky header + virtualized rows: bodyHeight / fillHeight. Only visible rows are built (tested with 100,000 rows).
• Column resize (drag the header edge, double-click to reset), drag & drop reorder (long-press), and "Reset columns".
• Per-column filter row (showColumnFilters) with ColumnFilterMatcher expressions (>10, 10..20, =x, !=x, !x, dates, a, b).
• Multi-column sort (Shift + click, setSorts, addSort) with level badges.
• Row grouping (groupByColumnId, collapsible groups, groupHeaderBuilder with TableGroupInfo), on desktop and mobile.
• Inline cell editing (isEditable, CellEditor.text / number / dropdown / date / boolean, cellValidator, onCellEdited, canEditCell), with Enter / Tab / Escape.
• Keyboard navigation: arrows, Enter / F2, Space, Tab, Home / End, Page Up / Down, Ctrl + A, Escape.
• Server-side data: AdaptiveTableDataSource / TableDataPage, stale-response protection, automatic last-page clamping, and a Retry button on errors.
• TableStateModel gained additionalSorts, columnFilters, groupByColumnId, sorts. TableLoaded gained columnWidths, columnOrder, columnPins, collapsedGroups, isFetching, arrange() and pinOf().
• Mobile cards are virtualized too when the table has a bounded height.
• Exports follow the user's column order.

New

• layoutMode (TableLayoutMode.auto / table / cards) to force the grid on phones or cards on desktop.
• onExportRequested / onPrintRequested to plug in your own export and print implementations.
• AdaptiveTableController to search, filter, sort, paginate and select from outside.
• onSelectionChanged, onTableStateChanged, onRowLongPress, rowColorBuilder, toolbarActions, isLoading, showClearFilters, showDateFilter, initialPageSize, initialSortColumnId / initialSortAscending, mobileBreakpoint, mobileTitleColumnId / mobileSubtitleColumnId, searchDebounce, firstDate / lastDate.
• Column options: valueFormatter, isSearchable, isExportable, isHideable. fieldName is now optional.
• TableExportOptions: file name, formats, PDF fonts and page format, "export selected rows only", and a custom onExport handler.
• AdaptiveTableLabels with English and Arabic built in, chosen from the app locale.
• AdaptiveTableTheme is now a ThemeExtension (copyWith, lerp, AdaptiveTableTheme.of), with an adaptive preset and new accentColor, onAccentColor, selectedRowColor, titleTextStyle, toolbarIconColor, summaryBackgroundColor and blurSigma.
• Tri-state "select all", numbered pagination, "Showing 11–20 of 48", a search clear button, a "Clear filters" button, and separate "no data" vs "no results" states.
• PDF: cached Cairo font with a timeout, custom fonts, automatic landscape, column widths and alignments.
• Excel: typed date cells, RTL sheets, automatic column widths.
• Desktop exports are saved to the Downloads folder, and the saved path is shown.
• TableCubit: sortBy, clearSort, setCustomFilter, resetFilters, resetAll, setSelection, setColumnVisibility, toggleRowExpansion, updateConfiguration, nextPage / previousPage. It emits TableError instead of crashing.
• FilterItemsUseCase.apply returns TableQueryResult (with totalPages and effectivePage). Supports hidden columns and search-only keys.
• DynamicFormField: hint, helperText, enabled, maxLines, firstDate / lastDate, copyWith, and inferType / tokenize. detectFromColumns gained fieldTypes, excludeIds and optionalIds. DynamicFormDialog.show returns the submitted values.

Behaviour changes

• An empty, optional number field now submits null instead of 0.
• Exports use the selected rows when there is a selection (turn this off with TableExportOptions(exportSelectedWhenAny: false)).
• saveAndShareFile returns Future<String?> (the saved path or file name).

Project

• 135 package tests + 6 example smoke tests (previously 7), a CI workflow, stricter lints, a rewritten README with screenshots, and a rebuilt example app with all platforms.
