Angel3 Paginate #




Platform-agnostic pagination library, with custom support for the Angel3.

Usage #
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...>"]
}
copied to clipboard
Results can be parsed from Maps using the PaginationResult<T>.fromMap constructor, and serialized via their toJson() method.
To create a paginator:
import 'package:angel3_paginate/angel3_paginate.dart';

void main() {
var p = new Paginator(iterable);

// Get the current page (default: page 1)
var page = p.current;
print(page.total);
print(page.startIndex);
print(page.data); // The actual items on this page.
p.next(); // 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.
