kr_paginate_firestore 1.0.4

A flutter package to simplify pagination with firestore data.

Pagination in Firestore

Setup

Use the same setup used for cloud_firestore package (or follow this).

Usage

In your pubspec.yaml

dependencies:
  kr_paginate_firestore: # latest version

Import it

import 'package:kr_paginate_firestore/paginate_firestore.dart';

Implement it

      KrPaginateFirestore(
        //item builder type is compulsory.
        itemBuilder: (context, documentSnapshots, index) {
          final data = documentSnapshots[index].data() as Map?;
          return ListTile(
            leading: CircleAvatar(child: Icon(Icons.person)),
            title: data == null ? Text('Error in data') : Text(data['name']),
            subtitle: Text(documentSnapshots[index].id),
          );
        },
        // orderBy is compulsory to enable pagination
        query: FirebaseFirestore.instance.collection('users').orderBy('name'),
        //Change types accordingly
        itemBuilderType: PaginateBuilderType.listView,
        // to fetch real-time data
        isLive: true,
      ),

To use with listeners:

      PaginateRefreshedChangeListener refreshChangeListener = PaginateRefreshedChangeListener();

      RefreshIndicator(
        child: KrPaginateFirestore(
          itemBuilder: (context, documentSnapshots, index) => ListTile(
            leading: CircleAvatar(child: Icon(Icons.person)),
            title: Text(documentSnapshots[index].data()['name']),
            subtitle: Text(documentSnapshots[index].id),
          ),
          // orderBy is compulsary to enable pagination
          query: Firestore.instance.collection('users').orderBy('name'),
          listeners: [
            refreshChangeListener,
          ],
        ),
        onRefresh: () async {
          refreshChangeListener.refreshed = true;
        },
      )
