Depending on when this happens, this may not be the ideal user experience for your application. If so, please refer to the next section on how to work around this. +For an explanation of the `onDidReceiveLocalNotification` callback associated with the `IOSInitializationSettings` class, please read [this](https://github.com/MaikuB/flutter_local_notifications/tree/master/flutter_local_notifications#handling-notifications-whilst-the-app-is-in-the-foreground). -⚠ If the app has been launched by tapping on a notification created by this plugin, calling `initialize` is what will trigger the `onSelectNotification` to trigger to handle the notification that the user tapped on. An alternative to handling the "launch notification" is to call the `getNotificationAppLaunchDetails` method that is available in the plugin. This could be used, for example, to change the home route of the app for deep-linking. Calling `initialize` will still cause the `onSelectNotification` callback to fire for the launch notification. It will be up to developers to ensure that they don't process the same notification twice (e.g. by storing and comparing the notification id). +*Note*: from version 4.0 of the plugin, calling `initialize` will not trigger the `onSelectNotification` callback when the application was started by tapping on a notification to trigger. Use the `getNotificationAppLaunchDetails` method that is available in the plugin if you need to handle a notification triggering the launch for an app e.g. change the home route of the app for deep-linking. ### [iOS (all supported versions) and macOS 10.14+] Requesting notification permissions @@ -495,11 +519,11 @@ Here the call to `flutterLocalNotificationsPlugin.resolvePlatformSpecificImpleme ```dart const AndroidNotificationDetails androidPlatformChannelSpecifics = - AndroidNotificationDetails( - 'your channel id', 'your channel name', 'your channel description', + AndroidNotificationDetails('your channel id', 'your channel name', + channelDescription: 'your channel description', importance: Importance.max, priority: Priority.high, - showWhen: false); + ticker: 'ticker'); const NotificationDetails platformChannelSpecifics = NotificationDetails(android: androidPlatformChannelSpecifics); await flutterLocalNotificationsPlugin.show( @@ -507,7 +531,9 @@ await flutterLocalNotificationsPlugin.show( payload: 'item x'); ``` -In this block of code, the details specific to the Android platform is specified.

Registering Types

- * Create a {@code RuntimeTypeAdapterFactory} by passing the base type and type field

   {@code

+ * Create a {@code RuntimeTypeAdapterFactory} by passing the base type and type field name to the
+ * {@link #of} factory method. If you don't supply an explicit type field name, {@code "type"} will
+ * be used.
+ *
+ * 
{@code
+ * RuntimeTypeAdapterFactory shapeAdapterFactory
+ *     = RuntimeTypeAdapterFactory.of(Shape.class, "type");
  * }

- * Next register all of your subtypes. Every subtype must be explicitly
- * registered. This protects your application from injection attacks. If you
- * don't supply an explicit type label, the type's simple name will be used.
- * 
   {@code
- *   shapeAdapter.registerSubtype(Rectangle.class, "Rectangle");
- *   shapeAdapter.registerSubtype(Circle.class, "Circle");
- *   shapeAdapter.registerSubtype(Diamond.class, "Diamond");
+ *
+ * Next register all of your subtypes. Every subtype must be explicitly registered. This protects
+ * your application from injection attacks. If you don't supply an explicit type label, the type's
+ * simple name will be used.
+ *
+ * 
{@code
+ * shapeAdapter.registerSubtype(Rectangle.class, "Rectangle");
+ * shapeAdapter.registerSubtype(Circle.class, "Circle");
+ * shapeAdapter.registerSubtype(Diamond.class, "Diamond");
  * }

+ *
  * Finally, register the type adapter factory in your application's GSON builder:
- * 
   {@code
- *   Gson gson = new GsonBuilder()
- *       .registerTypeAdapterFactory(shapeAdapterFactory)
- *       .create();
+ *
+ * 
{@code
+ * Gson gson = new GsonBuilder()
+ *     .registerTypeAdapterFactory(shapeAdapterFactory)
+ *     .create();
  * }

- * Like {@code GsonBuilder}, this API supports chaining: 
   {@code
- *   RuntimeTypeAdapterFactory shapeAdapterFactory = RuntimeTypeAdapterFactory.of(Shape.class)
- *       .registerSubtype(Rectangle.class)
- *       .registerSubtype(Circle.class)
- *       .registerSubtype(Diamond.class);
+ *
+ * Like {@code GsonBuilder}, this API supports chaining:
+ *
+ * 
{@code
+ * RuntimeTypeAdapterFactory shapeAdapterFactory = RuntimeTypeAdapterFactory.of(Shape.class)
+ *     .registerSubtype(Rectangle.class)
+ *     .registerSubtype(Circle.class)
+ *     .registerSubtype(Diamond.class);

+## [0.3.0]
+
+* **Breaking change** the `SelectNotificationCallback` typedef now maps to a function that returns `void` instead of a `Future`. This change was done to better communicate the plugin doesn't actually await any asynchronous computation and is similar to how button pressed callbacks work for Flutter where they are typically use [`VoidCallback`](https://api.flutter.dev/flutter/dart-ui/VoidCallback.html)
+
+## [0.2.0+1]
+
+* Fixed links to GNOME developer documentation referenced in API docs
+
+## [0.2.0]
+
+* Fixed issue when an app using the plugin is built on the web by using conditional imports
+* Changed the logic where notification IDs are saved so that `$XDG_RUNTIME_DIR` environment variable is not set but `$TMPDIR` is set, then they are saved to a file within the `/$TMPDIR/APP_NAME/USER_ID/SESSION_ID` directory. If `$TMPDIR` is not set then, it would save to `/tmp/APP_NAME/USER_ID/SESSION_ID`
+* Fixed an issue where errors would occur if the plugin was initialised multiple times
+
+## [0.1.0+1]
+
+*  Point to types within platform interface
+
+## [0.1.0]
+
+* Initial version for Linux

+## [5.0.0]
+
+* **Breaking change** the `SelectNotificationCallback` typedef now maps to a function that returns `void` instead of a `Future`. This change was done to better communicate the plugin doesn't actually await any asynchronous computation and is similar to how button pressed callbacks work for Flutter where they are typically use [`VoidCallback`](https://api.flutter.dev/flutter/dart-ui/VoidCallback.html)
+
+## [4.0.1]
+
+* Moved the `SelectNotificationCallback`  typedef and `validateId` method previously defined in the plugin to the platform interface. This is so they could be reused by platform implementations
+
+## [4.0.0]
+
+* Updated Flutter SDK constraint
+* Updated Dart SDK constraint
+* Bumped mockito dependency
+
+## [3.0.0]
+
+* Migrated to null safety
+
 ## [2.0.0+1]
 
 * Added more API docs
