CNotifySDK (flutter_cnotify_sdk)

CNotify allows you to create unlimited recurring notifications that can be scheduled using a No Code interface, as easily as scheduling an event in Google Calendar. For more details about CNotify, visit its website, and for more technical information, check out the documentation (also available in Spanish).

To see a detailed step-by-step guide on how to initialize the SDK in a Flutter app, visit the SDK → Flutter section of the documentation.

Getting Started

Let's install the CNotify SDK, which will allow us to receive notifications in our Flutter app that we'll set up later on the platform.

flutter pub add flutter_cnotify_sdk

Set up iOS and Android

In this step, you need to link a Firebase project with your app and configure specific settings for iOS and Android. For more details on this step, check out the documentation.

Note: The documentation specifies the correct locations for placing the google-services.json and GoogleService-Info.plist files.

Initialize the CNotify SDK

Open the lib/main.dart file or whichever file you’re using to initialize your app’s dependencies. It’s super important to instantiate the SDK as early as possible to quickly subscribe users to notifications. Remember, sending notifications is a really efficient communication tool in our projects.

In our case, we’ll initialize the SDK in the lib/main.dart file by modifying the main function to look like this:

import 'package:flutter_cnotify_sdk/cnotify_sdk.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await CNotifySdk.init(testing: kDebugMode);
  runApp(const MyApp());
}

The testing parameter allows you to receive test notifications on your device. For a development environment, it’s best to set it to true. However, make sure this value doesn’t make it to production, as it could lead to test notifications being sent to your app's end users.

The complete lib/main.dart file will look like this:

import 'package:flutter/material.dart';
import 'package:flutter_cnotify_sdk/cnotify_sdk.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await CNotifySdk.init(testing: kDebugMode);
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // TRY THIS: Try running your application with "flutter run". You'll see
        // the application has a purple toolbar. Then, without quitting the app,
        // try changing the seedColor in the colorScheme below to Colors.green
        // and then invoke "hot reload" (save your changes or press the "hot
        // reload" button in a Flutter-supported IDE, or press "r" if you used
        // the command line to start the app).
        //
        // Notice that the counter didn't reset back to zero; the application
        // state is not lost during the reload. To reset the state, use hot
        // restart instead.
        //
        // This works for code too, not just values: Most code changes can be
        // tested with just a hot reload.
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      // This call to setState tells the Flutter framework that something has
      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(
      appBar: AppBar(
        // TRY THIS: Try changing the color here to a specific color (to
        // Colors.amber, perhaps?) and trigger a hot reload to see the AppBar
        // change color while the other colors stay the same.
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,

        // in the middle of the parent.
        child: Column(
          // Column is also a layout widget. It takes a list of children and

          // children horizontally, and tries to be as tall as its parent.
          //

          // how it positions its children. Here we use mainAxisAlignment to
          // center the children vertically; the main axis here is the vertical
          // axis because Columns are vertical (the cross axis would be
          // horizontal).
