How to implement Flutter local notifications?

1. Install the package:

Add the flutter_local_notifications package to your pubspec.yaml file:

dependencies:
  flutter_local_notifications: ^{last_version}        

• Run flutter pub get to install the package.

2. Request permissions:

• Android: No explicit permission requests are needed for notifications.
• iOS: Request notification permissions using the requestPermissions method of the FlutterLocalNotificationsPlugin. Here's an example:

import 'package:flutter_local_notifications/flutter_local_notifications.dart';

void requestIOSPermissions() async {
  final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
      FlutterLocalNotificationsPlugin();

  const InitializationSettings initializationSettingsIOS =
      const InitializationSettings(
    requestAlertPermission: true,
    requestBadgePermission: true,
    requestSoundPermission: true,
  );
  await flutterLocalNotificationsPlugin.initialize(initializationSettingsIOS);
}        

3. Writing the Core Code:

• Create a LocalNotificationService class.
• Implement the initialize method to configure notifications.
• Implement the showTextNotification method to display notifications. Code snippet: (Show the code from the LinkedIn post) Image: A code editor displaying the implementation of the notification service Speaker notes:
• Guide the audience through the code structure and explain key methods.
• Highlight important configuration options for notifications.

import 'package:flutter_local_notifications/flutter_local_notifications.dart';

class LocalNotificationService {
  static FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
      FlutterLocalNotificationsPlugin();

  static Future<void> initialize() async {
    var androidInitialize =
        const AndroidInitializationSettings("@mipmap/ic_launcher");

/// iOS: Request notification permissions
    DarwinInitializationSettings initializationSettingsIOS =
        const DarwinInitializationSettings(
      requestAlertPermission: true,
      requestBadgePermission: true,
      requestSoundPermission: true,
    );

    InitializationSettings initializationSettings = InitializationSettings(
      android: androidInitialize,
      iOS: initializationSettingsIOS,
    );

    await flutterLocalNotificationsPlugin.initialize(initializationSettings);

  }

  static Future showTextNotification({
    int id = 0,
    required String title,
    required String body,
    bool playSound = true,
    bool enableVibration = true,
    var payload,
  }) async {

    AndroidNotificationDetails androidNotificationDetails =
        const AndroidNotificationDetails(
      "default_value",
      "channel_id_5",
      playSound: true,
      importance: Importance.max,
      priority: Priority.max,
      showWhen: true,
      showProgress: true,
      enableVibration: true,
    );

    DarwinNotificationDetails darwinInitializationDetails =
        const DarwinNotificationDetails(presentSound: true, presentAlert: true);

    var not = NotificationDetails(
      android: androidNotificationDetails,
      iOS: darwinInitializationDetails,
    );
    await flutterLocalNotificationsPlugin.show(id, title, body, not);

  }
}
