Installation

1. Add flutter_multi_table.dart: <latest-version> to your pubspec.yaml dependencies. And import it: Get the latest version in the 'Installing' tab on pub.dev

dependencies:
  flutter_multi_table: <latest-version>

flutter pub add flutter_multi_table

2. Run pub get.

flutter pub get

3. Import package.

import 'package:flutter_multi_table/flutter_multi_table.dart';

Basic Usage

// 1. Define your headers
List headers = [
  'No',
  'Name',
  'Age',
  'City',
  'Status',
];

// 2. Create initial data
List<Map> initialData = [
  {
    'No': '1',
    'Name': 'John',
    'Age': '',
    'City': 'New York',
    'Status': 'Active',
  },
  {
    'No': '2',
    'Name': 'Alice',
    'Age': '',
    'City': 'London',
    'Status': 'Inactive',
  },
];

// 3. Initialize controller
FlutterMultiTableController controller = FlutterMultiTableController(
  initialData: initialData,
  headers: headers,
);

// 4. Configure table
FlutterMultiTableConfig config = FlutterMultiTableConfig(
  headers: headers,
  hint: '....',
);

// 5. Use the widget
FlutterMultiTable(
  controller: controller,
  config: config,
)

Advanced Configuration

Table Configuration

FlutterMultiTableConfig config = FlutterMultiTableConfig(
  headers: headers,
  hint: '....',

  // Define which cells are read-only
  isReadOnly: (row, column) {
    if (column == 0 || column == 1 || column == 3 || column == 4) {
      return true;
    }
    return false;
  },

  // Configure dropdown cells
  isDropdown: (row, column) {
    if (column == 2 && (row != 1 && row != 13)) {
      return true;
    }
    return false;
  },
  dropdownOptions: ['Jakarta', 'New York', 'London', 'Tokyo', 'Paris'],

  // Handle value changes
  onChanged: (row, column, value) {
    print('Cell ($row, $column) changed to: $value');
  },

  // Validation
  validator: (row, column, value) {
    if (column == 2 && value.isEmpty) {
      return 'Data wajib diisi';
    }
    return null;
  },

  // Dropdown validation
  dropdownValidator: (row, column, value) {
    if (column == 2 && (value == null || value.isEmpty)) {
      return 'Data wajib diisi';
    }
    return null;
  },

  // Styling
  headerTextStyle: TextStyle(
    fontSize: 10,
    color: Colors.white,
    fontWeight: FontWeight.w700,
  ),
  errorTextStyle: TextStyle(fontSize: 8, color: Colors.red),
  cellTextStyle: TextStyle(
    fontSize: 6,
    fontWeight: FontWeight.w600,
  ),
  cellWidth: MediaQuery.of(context).size.width * 0.182,
  cellHeight: MediaQuery.of(context).size.height * 0.04,
  hintTextStyle: TextStyle(
    fontSize: 8,
    fontWeight: FontWeight.w400,
  ),
);

FlutterMultiTableController

Main controller class for managing table data and state:

Constructor

FlutterMultiTableController({
  required List<Map> initialData,
  required List headers,
})

Methods

• updateCell(int row, int column, String value): Updates specific cell value
• getCellValue(int row, int column): Gets value from specific cell
• setDropdownError(int row, int column, String? error): Sets dropdown error message
• getDropdownError(int row, int column): Gets dropdown error message
• dispose(): Cleans up resources

FlutterMultiTableConfig

Configuration class for customizing table appearance and behavior:

FlutterMultiTableConfig({
  required List headers,
  String hint = "",
  bool Function(int row, int column)? isReadOnly,
  bool Function(int row, int column)? isDropdown,
  List? dropdownOptions,
  void Function(int row, int column, String value)? onChanged,
  String? Function(int row, int column, String value)? validator,
  String? Function(int row, int column, String? value)? dropdownValidator,
  TextStyle? headerTextStyle,
  Color? headerBoxColor,
  TextStyle? cellTextStyle,
  TextStyle? hintTextStyle,
  TextStyle? errorTextStyle,
  TextInputType? textInputType,
  double? cellHeight,
  double? cellWidth,
})
