Define your fields and filter the list by keyword, date range, and number range. And sort it.

Introduction

Define your fields and filter the list by keyword, date range, and number range. And sort it. You can filter on frontend and backend.

Usage

First, define your filter as in the example below.

final List<FilterAction> employeeFilter = [
  FilterAction(
    title: 'Firstname',
    field: 'firstname',
  ),
  FilterAction(
    title: 'Age',
    field: 'age',
    type: FilterType.numberRangeFilter,
    numberRange: const RangeValues(18, 65),
  ),
  FilterAction(
    title: 'Hired date',
    field: 'hiredDate',
    type: FilterType.dateRangeFilter,
    dateRange: DateTimeRange(
      start: DateTime.now(),
      end: DateTime.now(),
    ),
  ),
];

final List<SortAction> employeeSort = [
  SortAction(
    title: 'Firstname ASC',
    field: 'firstname',
  ),
  SortAction(
    title: 'Email DESC',
    field: 'email',
    order: OrderType.desc,
  ),
  SortAction(
    title: 'Hired date ASC',
    field: 'hiredDate',
  ),
];

then use the SearchField widget.

SearchField(
  disableFilter: false, // if true, filters are disabled.
  filters: employeeFilter, // specify your filters
  sorts: employeeSort, // specify your sorts
  initialData: sampleList, // specify the data to filter.
  onChanged: (List<Employee> data) => setState(
    () => samples = data,
  ), // the value is returned in the onChanged method when filtering.
  onFilter: (Map filters) => print(filters), // The filter json data will be returned.
),

Customize filter

If you want to customize, you can wrap it with GlobalSearchbar widget. Then you need to define the SearchThemeData object. Here's an example with the following code

SearchThemeData(
  filterIcon: Icons.filter_list_sharp,
  title: 'Filter',
  filterTitle: 'Filters',
  sortTitle: 'Sorts',
  primaryColor: Colors.tealAccent,
  iconColor: const Color(0xFFE8E7E4),
  applyButton: ActionButtonTheme(
  title: 'Apply',
  style: ButtonStyle(
    backgroundColor:
      MaterialStateProperty.all<Color>(const Color(0xFF348FFF)),
    ),
  ),
  clearFilterButton: ActionButtonTheme(
  title: 'Clear filter',
  style: ButtonStyle(
    backgroundColor:
      MaterialStateProperty.all<Color>(const Color(0xFF3DD89B)),
    ),
  ),
  cancelButton: ActionButtonTheme(
  title: 'Cancel',
  style: ButtonStyle(
    backgroundColor:
      MaterialStateProperty.all<Color>(const Color(0xFFE8E7E4)),
    ),
  ),
),
