Platform-agnostic pagination library, with custom support for the Angel framework.


In your pubspec.yaml file:

  angel_paginate: ^1.0.0


This library exports a Paginator<T>, which can be used to efficiently produce instances of PaginationResult<T>. Pagination results, when serialized to JSON, look like this:

  "total" : 75,
  "items_per_page" : 10,
  "previous_page" : 3,
  "current_page" : 4,
  "next_page" : 5,
  "start_index" : 30,
  "end_index" : 39,
  "data" : ["<items...>"]

Results can be parsed from Maps using the PaginationResult<T>.fromMap constructor, and serialized via their toJson() method.

To create a paginator:

import 'package:angel_paginate/angel_paginate.dart';

main() {
  var p = new Paginator(iterable);
  // Get the current page (default: page 1)
  var page = p.current;
  print(; // The actual items on this page.; // Advance a page
  p.back(); // Back one page
  p.goToPage(10); // Go to page number (1-based, not a 0-based index)

The entire Paginator API is documented, so check out the DartDocs.

Paginators by default cache paginations, to improve performance as you shift through pages. This can be especially helpful in a client-side application where your UX involves a fast response time, i.e. a search page.

Use With Angel

Naturally, a library named angel_paginate has special provisions for the Angel framework.

In package:angel_paginate/server.dart, a function called paginate generates pagination service hooks for you. If the result of a hooked service event is an Iterable, it will be paginated. This is convenient because it works with any data store, whether it be MongoDB, RethinkDB, an in-memory store, or something else entirely.

configureServer(Angel app) {
  var service = app.service('api/foo') as HookedService;
  service.afterIndexed.listen(paginate(itemsPerPage: 10));

See test/server_test.dart for examples of usage with Angel.

The pagination hook also allows you to provide a page and/or $limit in the query. If the user provides a page in the query, it will return a pagination of the given page.


A $limit can be used to override the itemsPerPage set in the paginate hook. If you would like to set a maximum on the number of items per page, you can set maxItemsPerPage in the paginate call.


You can use these pagination functions to provide powerful search experiences on your websites.

NOTE: If the paginated data is empty, expect start_index and end_index to both be -1.
