flutter_table_layout 0.1.0

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

flutter_table_layout

Adaptive data tables for Flutter. One widget gives you a dense data grid on desktop and web, and expandable cards on phones. It comes with search, date and custom filters, sorting, pagination, selection, summaries, Excel / Word / PDF export, printing, auto-generated CRUD forms, five themes, and full RTL (Arabic) support.

The grid also covers the "spreadsheet" features: frozen columns, sticky header with virtualized rows (100k+ rows), column resize and drag & drop reorder, a per-column filter row, multi-column sort, row grouping, inline cell editing, keyboard navigation, and server-side data sources.

Features

📱 Adaptive layout	Data grid above mobileBreakpoint (600 px by default). Below it, rows become expandable cards. Horizontal scrolling kicks in when the columns don't fit.
🔎 Search	Debounced, case-insensitive search over visible and searchable columns. Dates also match yyyy-MM-dd.
📅 Filters	Inclusive date range with a "Query" button mode, your own filter widgets (customFilters), and a "Clear filters" button.
↕️ Sorting	Stable sort. Numbers, strings (case-insensitive), dates and booleans compare naturally, and null always sorts last.
📄 Pagination	Numbered pages, a rows-per-page menu, "Showing 11–20 of 48". The current page is clamped automatically when data shrinks.
☑️ Selection	Row checkboxes, a tri-state select all, onSelectionChanged, and a selection badge. Exports use only the selected rows when there are any.
🧩 Expandable rows	expandedRowBuilder adds a details panel on desktop and mobile.
🧮 Summary row	summaryBuilder receives every filtered row, across all pages.
📤 Export	Excel .xlsx with typed cells, Word .doc, PDF (auto landscape, Arabic font), and system printing. Web downloads the file, mobile opens the share sheet, desktop saves to Downloads.
📝 Dynamic forms	Generate add/edit dialogs from your columns, with validation and typed values.
🎨 Themes	adaptive, light, dark, glassmorphic, gradient, cozy. It's a ThemeExtension, so you can register it once for the whole app.
🌍 i18n and RTL	English and Arabic built in, every string can be overridden, and layout, alignment and icons mirror in RTL.
🧊 Frozen columns	Pin columns at the start or end (pin: ColumnPin.start); users can pin from the columns menu. LTR and RTL.
🚀 Large data	bodyHeight / fillHeight: sticky header and lazily built rows. Tested with 100,000 rows.
↔️ Column layout	Resize by dragging the header edge (double-click resets), reorder by long-press + drag, "Reset columns".
🧪 Column filters	A filter row under the header: text, =x, !=x, >10, <=5, 10..20, a, b, dates >=2026-01-01.
🔢 Multi-sort	Shift + click adds secondary sort levels, shown as 1, 2, 3 in the header.
🗂️ Grouping	groupByColumnId, collapsible groups, per-group aggregates via groupHeaderBuilder.
✏️ Inline editing	Double-click or Enter to edit text, number, dropdown, date or boolean cells, with validation and per-cell permissions.
⌨️ Keyboard	Arrows, Enter/F2, Tab, Space, Home/End, Page Up/Down, Ctrl+A, Escape.
☁️ Server-side	AdaptiveTableDataSource: search, filters, sort and paging are sent to your API. Stale responses are ignored.
🕹️ Controller	AdaptiveTableController to search, filter, sort, paginate and select from anywhere.

Installation

dependencies:
  flutter_table_layout: ^0.1.0

flutter pub get

Requires Flutter ≥ 3.35 / Dart ≥ 3.9.

Platform notes

• macOS: printing and saving files need the sandbox entitlements com.apple.security.print and com.apple.security.files.downloads.read-write.
• Android / iOS: exports open the native share sheet (share_plus).
• Web: exports download directly in the browser.

Quick start

import 'package:flutter/material.dart';
import 'package:flutter_table_layout/flutter_table_layout.dart';

class Invoice {
  final int id;
  final String customer;
  final double total;
  final DateTime date;
  final bool paid;
  const Invoice(this.id, this.customer, this.total, this.date, this.paid);
}

class InvoicesPage extends StatelessWidget {
  const InvoicesPage({super.key, required this.invoices});
  final List<Invoice> invoices;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SingleChildScrollView(
        child: AdaptiveTableLayout<Invoice>(
          title: 'Invoices',
          subtitle: 'All invoices of the current year',
          items: invoices,
          columns: [
            AdaptiveTableColumn(id: 'id', title: '#', width: 70),
            AdaptiveTableColumn(id: 'customer', title: 'Customer', flex: 2),
            AdaptiveTableColumn(
              id: 'total',
              title: 'Total',
              alignment: TableColumnAlignment.end,
              valueFormatter: (v) => '\$${(v as double).toStringAsFixed(2)}',
            ),
            AdaptiveTableColumn(id: 'date', title: 'Date', width: 120),
            AdaptiveTableColumn(
              id: 'paid',
              title: 'Status',
              width: 110,
              cellBuilder: (context, inv) => Chip(
                label: Text(inv.paid ? 'Paid' : 'Open'),
              ),
            ),
          ],
          // One extractor per column id. Used for search, sort and export.
          valueProviders: {
            'id': (i) => i.id,
            'customer': (i) => i.customer,
            'total': (i) => i.total,
            'date': (i) => i.date,
            'paid': (i) => i.paid ? 'Paid' : 'Open',
          },
          dateProvider: (i) => i.date, // enables the From / To filter
        ),
      ),
    );
  }
}

💡 items may be a new list or the same list changed in place. Either way the table refreshes on the next rebuild.

Columns

AdaptiveTableColumn<T> describes one column:

Property	Default	Description
id	required	Unique key. It must match the key in valueProviders.
title	required	Header text. Single words are never split mid-word, they shrink to fit instead.
fieldName	id	Field name, used by the dynamic form type detection.
width / flex	null / 1	Fixed width, or a flex share of the remaining space.
alignment	start	start, center or end. Direction-aware, so end is the left edge in RTL.
cellBuilder	null	Custom cell widget.
headerBuilder	null	Custom header widget.
valueFormatter	null	Formats the raw value for text cells, mobile cards and PDF/Word exports. Excel keeps the raw typed value.
isSortable	true	Tapping the header toggles ascending / descending.
isVisible	true	Initial visibility. Users can still toggle it from the columns menu.
isHideable	true	Whether users may hide the column. The last visible column can never be hidden.
isSearchable	true	Include in global search.
isExportable	true	Include in exports and printing. Set false for action columns.
pin	ColumnPin.none	Freeze at the start or end (desktop grid).
minWidth	60	Smallest width when resizing or squeezing.
isResizable	true	Allow resizing by dragging the header edge.
isFilterable	true	Show a field in the per-column filter row.
isEditable	false	Allow inline editing (with onCellEdited).
editor	inferred	CellEditor.text / number / dropdown(options) / date / boolean.
cellValidator	null	Validates inline edits. Return an error message to keep the editor open.

AdaptiveTableColumn<Currency>(
  id: 'actions',
  title: 'Actions',
  width: 130,
  isSortable: false,
  isSearchable: false,
  isExportable: false, // not written to Excel / PDF / Word
  cellBuilder: (context, c) => Row(
    mainAxisSize: MainAxisSize.min,
    children: [
      IconButton(icon: const Icon(Icons.edit), onPressed: () => edit(c)),
      IconButton(icon: const Icon(Icons.delete), onPressed: () => delete(c)),
    ],
  ),
),

[Columns menu (dark theme)]

Search, filters and sorting

AdaptiveTableLayout<Transaction>(
  // …
  showSearch: true,                          // default
  searchDebounce: const Duration(milliseconds: 250),
  dateProvider: (t) => t.date,               // shows From / To pickers
  firstDate: DateTime(2020), lastDate: DateTime(2030),
  onQueryPressed: () {},                     // optional: apply dates only on "Query"
  initialSortColumnId: 'date',
  initialSortAscending: false,

  // Custom filters: any widget, plus a matcher.
  customFilterMatcher: (t, filters) =>
      filters['currency'] == null || t.currency == filters['currency'],
  customFilters: const [CurrencyFilter()],
)

A custom filter widget is built under the table, so it can talk to the table directly:

class CurrencyFilter extends StatelessWidget {
  const CurrencyFilter({super.key});

  @override
  Widget build(BuildContext context) {
    final cubit = context.watch<TableCubit<Transaction>>();
    final current = cubit.tableState.customFilters['currency'] as String?;
    return SegmentedButton<String>(
      segments: const [
        ButtonSegment(value: 'all', label: Text('All')),
        ButtonSegment(value: 'USD', label: Text('USD')),
        ButtonSegment(value: 'SAR', label: Text('SAR')),
      ],
      selected: {current ?? 'all'},
      onSelectionChanged: (s) =>
          cubit.setCustomFilter('currency', s.first == 'all' ? null : s.first),
    );
  }
}

Value providers whose key doesn't match any column are search-only keys. For example, 'tags': (t) => t.tags.join(' ') makes tags searchable without showing a column.

Pagination

AdaptiveTableLayout<T>(
  pageSizes: const [10, 25, 50, 100],
  initialPageSize: 25,
  showPagination: true, // false = render every row, no footer
)

Selection, row taps and expandable rows

AdaptiveTableLayout<Transaction>(
  showSelection: true,
  onSelectionChanged: (rows) => setState(() => selected = rows),
  onRowTap: (t) => openDetails(t),          // when null, a tap expands the row
  onRowLongPress: (t) => showMenu(t),
  rowColorBuilder: (t) => t.isOverdue ? Colors.red.withValues(alpha: .06) : null,
  expandedRowBuilder: (context, t) => TransactionDetails(t),
  mobileTitleColumnId: 'details',           // card title on phones
  mobileSubtitleColumnId: 'amount',         // card subtitle on phones
)

Summary row

summaryBuilder receives all filtered rows, not only the current page:

summaryBuilder: (context, rows) {
  final total = rows.fold<double>(0, (s, r) => s + r.amount);
  return Text('Total: ${total.toStringAsFixed(2)}');
},

Controlling the table from outside

final controller = AdaptiveTableController<Invoice>();

AdaptiveTableLayout<Invoice>(controller: controller, /* … */);

controller.search('acme');
controller.setDateRange(DateTime(2026, 1, 1), null);
controller.setCustomFilter('status', 'open');
controller.sortBy('total', ascending: false);
controller.goToPage(2);
controller.setColumnVisibility('notes', false);
controller.selectAll();
controller.setColumnFilter('total', '>100');
controller.addSort('date');                  // secondary sort level
controller.groupBy('customer');
controller.setColumnPin('customer', ColumnPin.start);
controller.refresh();                        // reload (server mode)

final rows = controller.filteredItems;   // all pages, filtered and sorted
final picked = controller.selectedItems;
controller.resetFilters();

The controller is a ChangeNotifier, so ListenableBuilder(listenable: controller, …) rebuilds on every table change. Use onTableStateChanged to persist the search/sort/page state, or to drive server-side queries.

Loading and empty states

AdaptiveTableLayout<T>(
  isLoading: isFetching,            // spinner, or a progress bar over existing rows
  loadingWidget: const MyShimmer(),
  emptyWidget: const MyEmptyState(), // otherwise "No data" / "No results"
)

If a value provider throws, the table shows an error message instead of crashing, and recovers on the next change.

Layout mode (grid or cards)

AdaptiveTableLayout<T>(
  layoutMode: TableLayoutMode.auto,  // default: cards below mobileBreakpoint
  // layoutMode: TableLayoutMode.table, // always the grid (scrolls horizontally on phones)
  // layoutMode: TableLayoutMode.cards, // always cards, even on desktop
  mobileBreakpoint: 700,             // only used by `auto`
)

The toolbar and footer always adapt to the available width, whatever the mode.

Advanced grid

[Frozen columns and per-column filters]

Everything below works on desktop and web. On phones the same table switches to cards, with grouping and virtualization still working.

Sticky header and virtualization (large data)

Give the rows a bounded height and only the visible rows are built, while the header stays on top:

// A fixed rows area…
AdaptiveTableLayout<Employee>(
  items: employees,            // e.g. 100,000 rows
  showPagination: false,       // one long, lazily built list
  bodyHeight: 520,
  columns: columns,
  valueProviders: providers,
)

// …or fill the parent (Expanded, SizedBox, a TabBarView page…)
Expanded(
  child: AdaptiveTableLayout<Employee>(
    fillHeight: true,
    items: employees,
    columns: columns,
    valueProviders: providers,
  ),
)

fillHeight is ignored (with a debug message) when the parent height is unbounded, for example inside a SingleChildScrollView.

Frozen columns

AdaptiveTableColumn(id: 'id', title: 'ID', width: 80, pin: ColumnPin.start),
AdaptiveTableColumn(id: 'name', title: 'Name', width: 200, pin: ColumnPin.start),
// … scrollable columns …
AdaptiveTableColumn(id: 'actions', title: 'Actions', width: 110, pin: ColumnPin.end),

• Pinned columns stay visible while the other columns scroll horizontally. start and end follow the text direction.
• The selection and expand columns are always pinned.
• Users can pin or unpin any column from the 📌 button in the columns menu, or you can call controller.setColumnPin('city', ColumnPin.start).

Resize and reorder columns

• Resize: drag the right edge of a header. Double-click the edge to restore the declared width.
• Reorder: long-press a header, then drag it onto another header.
• Reset: the columns menu has a "Reset columns" item, or call controller.resetColumnLayout().

AdaptiveTableLayout<T>(
  allowColumnResize: true,   // default
  allowColumnReorder: true,  // default
  columns: [
    AdaptiveTableColumn(id: 'notes', title: 'Notes', minWidth: 120),
    AdaptiveTableColumn(id: 'actions', title: '', isResizable: false),
  ],
)
// From code:
controller.setColumnWidth('notes', 300);
controller.moveColumn('salary', beforeColumnId: 'name');

Per-column filter row

AdaptiveTableLayout<T>(showColumnFilters: true, /* … */)

Type in a column filter	Keeps rows where the value…
acme	contains "acme" (case-insensitive)
=paid / !=paid	equals / differs
!test	does not contain "test"
>1000, >=1000, <50, <=50	compares as a number, date or text
100..500	is within the range (inclusive)
>=2026-01-01	is on or after a date
USD, SAR	matches any of the parts (OR)

Column filters combine with each other and with the search box using AND. Set isFilterable: false to skip a column. From code: controller.setColumnFilter('salary', '>=3000'). The expressions are also sent to your server in TableStateModel.columnFilters.

Multi-column sort

Click a header to sort, and Shift + click other headers to add secondary sort levels, shown as 1, 2… next to the arrow. From code:

controller.setSorts(const [ColumnSort('department'), ColumnSort('salary', ascending: false)]);
controller.addSort('name');

Row grouping

[Grouping and inline editing]   [Grouped cards on a phone (Arabic)]

AdaptiveTableLayout<Employee>(
  groupByColumnId: 'department',               // or controller.groupBy('city')
  groupHeaderBuilder: (context, group) => Text(
    'Avg: ${group.rows.map((e) => e.salary).reduce((a, b) => a + b) / group.rows.length}',
  ),
)

• Click a group header to collapse or expand it.
• group.rows holds every row of the group across all pages, so aggregates cover the whole group.
• Rows are ordered by the group column first, then by the user's sort.

Inline cell editing

AdaptiveTableLayout<Employee>(
  items: employees,
  columns: [
    AdaptiveTableColumn(id: 'name', title: 'Name', isEditable: true,
        cellValidator: (v) => (v as String).trim().isEmpty ? 'Required' : null),
    AdaptiveTableColumn(id: 'salary', title: 'Salary', isEditable: true), // number editor (inferred)
    AdaptiveTableColumn(id: 'dept', title: 'Department', isEditable: true,
        editor: const CellEditor.dropdown(['Sales', 'IT', 'HR'])),
    AdaptiveTableColumn(id: 'hiredOn', title: 'Hired', isEditable: true), // date picker (inferred)
    AdaptiveTableColumn(id: 'active', title: 'Active', isEditable: true), // toggles on double-click
  ],
  // Permissions: per row / per column.
  canEditCell: (e, column) => user.canEdit && e.isActive,
  // Save the change. Return false (or throw) to reject it.
  onCellEdited: (e, column, value) async {
    final ok = await api.update(e.id, {column: value});
    if (ok) setState(() => employees = [for (final x in employees) x.id == e.id ? x.copyWith(column, value) : x]);
    return ok;
  },
)

Action	Result
Double-click, Enter or F2	Start editing
Enter	Save
Tab / Shift+Tab	Save and edit the next / previous cell
Escape	Cancel
Click outside	Save

The editor is inferred from the value (num → number, DateTime → date picker, bool → toggle, otherwise text) unless you set editor. Numbers accept 1,250.5. Invalid values keep the editor open with an error.

Keyboard navigation

Click a cell, then:

Key	Action
← → ↑ ↓	Move between cells (mirrored in RTL)
Enter / F2	Edit, or run onRowTap / expand the row
Space	Select the row
Home / End (+Ctrl)	First / last column (row)
Page Up / Page Down	Previous / next page
Ctrl/Cmd + A	Select all
Escape	Leave the cell

Turn it off with enableKeyboardNavigation: false.

Server-side data

[Server-side data source]

class _InvoicesState extends State<InvoicesPage> {
  // Create the source once, not in build().
  late final source = AdaptiveTableDataSource<Invoice>.fromCallback((q) async {
    final res = await api.getInvoices(
      page: q.currentPage,
      size: q.pageSize,
      search: q.searchQuery,
      sort: [for (final s in q.sorts) '${s.columnId}:${s.ascending ? 'asc' : 'desc'}'],
      filters: q.columnFilters,   // {'total': '>100', 'status': '=paid'}
      from: q.startDate, to: q.endDate,
    );
    return TableDataPage(items: res.items, totalCount: res.total);
  });

  @override
  Widget build(BuildContext context) => AdaptiveTableLayout<Invoice>(
    dataSource: source,            // `items` is not needed
    columns: columns,
    valueProviders: providers,
    showColumnFilters: true,
    fillHeight: true,
  );
}

• Every change to the search, filters, sort, page or page size calls fetch.
• A progress bar shows while a request is in flight, and out-of-order responses are ignored.
• On error, the table shows a Retry button (controller.refresh() also reloads).
• If the server has fewer pages than the current page, the table moves to the last page automatically.
• Selection and exports work on the rows of the current page. Use onExportRequested for server-side exports.
• Tip: FilterItemsUseCase is pure Dart, so your Dart backend can run exactly the same filtering and sorting.

Export and printing

The toolbar has Excel, Word, PDF and Print actions. Exports:

• respect the current search, filters and sort order;
• export only the selected rows when some are selected (exportSelectedWhenAny);
• skip hidden columns and columns with isExportable: false;
• escape HTML in the Word output, and use safe file and sheet names, including Arabic titles;
• save the file where it belongs: a browser download on web, the share sheet on mobile, and ~/Downloads on desktop (with a snackbar showing the path).

AdaptiveTableLayout<T>(
  exportOptions: TableExportOptions(
    fileName: 'statement_2026',
    formats: {ExportFormat.excel, ExportFormat.pdf},
    pdfFont: myRegularFont,       // pw.Font.ttf(await rootBundle.load('assets/Cairo-Regular.ttf'))
    pdfBoldFont: myBoldFont,
    pdfPageFormat: PdfPageFormat.a4.landscape,
    // Handle the bytes yourself (upload, e-mail…) instead of saving:
    onExport: (format, bytes, fileName) async => upload(bytes, fileName),
  ),
)

Use your own export or print (for example your company PDF template). The table gives you the rows it would export: the selected rows if any, otherwise all filtered rows, in the current sort order.

AdaptiveTableLayout<Invoice>(
  onExportRequested: (format, rows) async {
    if (format == ExportFormat.pdf) {
      final bytes = await MyInvoicePdf.build(rows);
      await saveAndShareFile(bytes: bytes, fileName: 'invoices.pdf',
          mimeType: format.mimeType);
    }
  },
  onPrintRequested: (rows) => MyPrinter.print(rows),
)

Arabic PDFs offline: by default the Cairo font is downloaded from Google Fonts once, then cached. Offline apps should bundle a font and pass pdfFont.

The exporters also work on their own:

final bytes = await const ExcelExporter().generateExcel<Invoice>(
  sheetName: 'Invoices',
  columns: columns.map((c) => c.definition).toList(),
  items: invoices,
  valueProviders: providers,
);
await saveAndShareFile(bytes: bytes, fileName: 'invoices.xlsx',
    mimeType: ExportFormat.excel.mimeType);

Dynamic forms (CRUD)

[Dynamic form dialog]

Generate a form from your columns and get typed values back:

final values = await DynamicFormDialog.show(
  context,
  title: 'New transaction',
  fields: DynamicFormField.detectFromColumns(
    columns,
    dropdownItems: {'currency': ['YER', 'SAR', 'USD']},
    excludeIds: {'id', 'actions'},
    initialValues: {'currency': 'USD'},      // e.g. when editing
    fieldTypes: {'status': FieldType.text},  // override the detection
  ),
);
if (values != null) {
  // values['amount'] is num?, values['date'] is DateTime, values['paid'] is bool…
}

Type detection works on whole words of fieldName / id (createdAt, created_at and Created At all split into created + at):

Detected type	Matches	Widget	Value
boolean	starts with is/has/can/should/allow, or contains active, enabled, status, visible	SwitchListTile	bool
date	contains date, day, time, birthday, dob, or ends with at/on	date picker	DateTime
number	contains id, amount, price, rate, total, qty, count, balance, discount, …	numeric field	num? (null if left empty)
dropdown	column listed in dropdownItems	DropdownButtonFormField	String?
text	anything else	TextFormField	String?

Manual fields support validator (called for every type), hint, helperText, enabled, maxLines, firstDate and lastDate:

DynamicFormField(
  id: 'email',
  label: 'E-mail',
  type: FieldType.text,
  isRequired: true,
  hint: '[e-mail]',
  validator: (v) => (v as String?)?.contains('@') == true ? null : 'Invalid e-mail',
),

Hiding features and permissions

Every part of the table can be turned off, and a button whose callback is null is not shown. So permissions are just values:

final canEdit = user.can('invoices.edit');

AdaptiveTableLayout<Invoice>(
  showSearch: true,
  showDateFilter: false,                    // hide the From / To pickers
  showExport: user.can('invoices.export'),
  showPrint: user.can('invoices.print'),
  showSelection: canEdit,
  showColumnsToggle: true,
  showPagination: true,
  showSummary: user.can('invoices.totals'),
  showClearFilters: true,
  onAddNewPressed: user.can('invoices.create') ? openMyAddDialog : null,
  onRefreshPressed: reload,
  exportOptions: const TableExportOptions(formats: {ExportFormat.excel}), // only Excel
  columns: [
    // …
    if (canEdit)
      AdaptiveTableColumn(
        id: 'actions', title: 'Actions', width: 130,
        isSortable: false, isSearchable: false, isExportable: false,
        cellBuilder: (context, inv) => Row(mainAxisSize: MainAxisSize.min, children: [
          IconButton(icon: const Icon(Icons.edit), onPressed: () => openMyEditDialog(inv)),
          if (user.can('invoices.delete'))
            IconButton(icon: const Icon(Icons.delete), onPressed: () => delete(inv)),
        ]),
      ),
  ],
  onRowTap: canEdit ? openMyEditDialog : null,
)

• The filter bar disappears when search, the date filter and custom filters are all off.
• The toolbar disappears when there is no title and no action.
• onAddNewPressed can open any dialog or page, so DynamicFormDialog is optional.
• Sensitive columns: include them only when allowed (if (user.isAdmin) AdaptiveTableColumn(...)), or use isHideable: false / isExportable: false.

  borderRadius: BorderRadius.circular(4),
  useAlternateRows: false,
  accentColor: Colors.deepPurple,
)

Register a theme once for the whole app. It also animates between light and dark:

MaterialApp(
  theme: ThemeData(extensions: [myTableTheme]),
)

Main theme properties: cardBackgroundColor, borderRadius, cardBorder, cardShadow, cardMargin, toolbarBackgroundColor, headerBackgroundColor, headerTextStyle, titleTextStyle, rowBackgroundColor, alternateRowBackgroundColor, useAlternateRows, rowTextStyle, rowPadding, rowHoverColor, selectedRowColor, dividerColor, footerBackgroundColor, footerTextStyle, summaryBackgroundColor, accentColor, onAccentColor, actionIconColor, toolbarIconColor, statusPositiveColor, statusNegativeColor, headerGradient, footerGradient, enableGlassmorphism, blurSigma.

Localization and RTL

[Arabic RTL desktop]

• Labels come from AdaptiveTableLabels.of(context): Arabic when the app locale is ar, English otherwise.
• Pass labels: AdaptiveTableLabels.en.copyWith(search: 'Buscar…', …) (or a whole new AdaptiveTableLabels) for any other language.
• The older searchHint, dateFromLabel, dateToLabel and queryButtonLabel parameters still work and override the labels.
• In RTL, the layout, column alignments, pagination arrows and expand icons are mirrored, Excel sheets are right-to-left, and Word/PDF documents use dir="rtl".

Where this package is stronger: it's the only one that turns into cards on phones automatically, it ships Arabic out of the box, exports to Excel, Word and PDF and prints without add-ons, and generates CRUD forms from your columns. All of that sits in one MIT-licensed widget, with the same API on phone, tablet, desktop and web.

Where the others are still ahead: Excel-style clipboard copy/paste, multi-cell range selection, row drag & drop, stacked (multi-level) headers, tree data, and cell merging. These are not implemented here yet.

Using the logic without the UI

The domain layer is plain Dart and can be used anywhere, for example on a server:

final result = const FilterItemsUseCase().apply<Invoice>(
  items: invoices,
  columns: const [ColumnDefinition(id: 'customer', title: 'Customer')],
  state: const TableStateModel(searchQuery: 'acme', sortByColumnId: 'total',
      sortAscending: false, currentPage: 1, pageSize: 20),
  valueProviders: {'customer': (i) => i.customer, 'total': (i) => i.total},
);
print('${result.totalCount} rows, ${result.totalPages} pages');

TableCubit<T> holds the reactive state (via flutter_bloc) if you want to build your own UI.

Running the example and tests

cd example && flutter run            # android / ios / web / windows / macos / linux
flutter test                          # from the package root

The screenshots in this README are generated from the example app:

cd example
flutter test test/screenshots_test.dart --update-goldens \
  --dart-define=SCREENSHOTS=true --dart-define=ARABIC_FONT_DIR=/path/to/cairo

بالعربية

flutter_table_layout مكتبة جداول ذكية لـ Flutter. تعرض البيانات كجدول كامل على الكمبيوتر والويب، وتحوّلها تلقائياً إلى بطاقات قابلة للتوسيع على الجوال. تدعم العربية واتجاه RTL بالكامل.

أهم المزايا: (ومعها تثبيت الأعمدة، والتعديل المباشر، والتجميع، والفلترة لكل عمود، والبيانات من السيرفر)

• بحث فوري، وفلترة بالتاريخ (من / إلى)، وفلاتر مخصصة، وزر لمسح الفلاتر.
• فرز ثابت يفهم الأرقام والنصوص والتواريخ، وترقيم صفحات بأرقام وعدد صفوف قابل للتغيير.
• تحديد الصفوف مع استدعاء onSelectionChanged، وصفوف قابلة للتوسيع لعرض التفاصيل، وصف ملخص للإجماليات.
• تصدير إلى Excel وWord وPDF (بخط عربي) وطباعة مباشرة. عند تحديد صفوف يُصدَّر المحدد منها فقط، ولا تُصدَّر الأعمدة المخفية.
• نماذج إضافة وتعديل تُولَّد تلقائياً من الأعمدة مع التحقق من الإدخال.
• ستة أنماط تصميم (تلقائي، فاتح، داكن، زجاجي، متدرج، مريح) قابلة للتعديل بـ copyWith.
• نصوص عربية وإنجليزية جاهزة تُختار حسب لغة التطبيق، ويمكن تخصيص أي نص.
• متحكم AdaptiveTableController للتحكم بالجدول من خارجه.

مثال سريع:

AdaptiveTableLayout<Transaction>(
  title: 'كشف الحساب',
  items: transactions,
  columns: [
    AdaptiveTableColumn(id: 'date', title: 'التاريخ', width: 120),
    AdaptiveTableColumn(id: 'details', title: 'البيان', flex: 2),
    AdaptiveTableColumn(id: 'amount', title: 'المبلغ',
        alignment: TableColumnAlignment.end),
  ],
  valueProviders: {
    'date': (t) => t.date,
    'details': (t) => t.details,
    'amount': (t) => t.amount,
  },
  dateProvider: (t) => t.date,
  summaryBuilder: (context, rows) =>
      Text('الإجمالي: ${rows.fold<double>(0, (s, t) => s + t.amount)}'),
)

لتظهر النصوص بالعربية، اضبط لغة التطبيق على ar (مع flutter_localizations)، أو مرّر labels: AdaptiveTableLabels.ar.

ميزات الشبكة المتقدمة (باختصار):

الميزة	طريقة الاستخدام
تثبيت أعمدة	pin: ColumnPin.start أو ColumnPin.end في العمود، أو زر 📌 في قائمة الأعمدة
بيانات ضخمة مع رأس ثابت	bodyHeight: 500 أو fillHeight: true مع showPagination: false
تغيير عرض الأعمدة وترتيبها	اسحب حافة رأس العمود، أو اضغط مطولاً على الرأس واسحبه
فلتر لكل عمود	showColumnFilters: true، ثم اكتب مثلاً >1000 أو 100..500 أو =مدفوع
فرز بأكثر من عمود	Shift + نقر على رؤوس الأعمدة
تجميع الصفوف	groupByColumnId: 'department' وgroupHeaderBuilder للإجماليات
التعديل المباشر	isEditable: true في العمود + onCellEdited + canEditCell للصلاحيات
لوحة المفاتيح	الأسهم وEnter وTab وEsc وSpace
بيانات من السيرفر	dataSource: AdaptiveTableDataSource.fromCallback((q) async => ...)
