 * [Android] **Breaking change** renamed the `requestPermission()` associated with the `AndroidFlutterLocalNotificationsPlugin` class to `requestNotificationsPermission()`. This was done to be more explicit given another method (`requestExactAlarmsPermission()`) has been added that also requests a permission (more details below).
 * [Android] **Breaking change** the plugin now only declares the bare minimum in its `AndroidManifest.xml`. This means applications making use of either scheduled notifications, full-screen intent notifications or notification actions will now require changes in the application's own `AndroidManifest.xml` file. Please check the [AndroidManifest.xml setup](https://pub.dev/packages/flutter_local_notifications#androidmanifestxml-setup) section of the readme for more details. The reason this was done was because not all applications will leverage all of the plugin's features. Doing this will now allow applications to only request the appropriate permissions needed for their application. This addresses issue [1687](https://github.com/MaikuB/flutter_local_notifications/issues/1687)
 * [Android] added the ability to request permission to schedule exact alarms via the `requestExactAlarmsPermission()` method that has been added to the `AndroidFlutterLocalNotificationsPlugin` class that represents the Android implementation of the plugin. This has been done in response to behaviour changes introduced in Android 14 (API level 34) when comes to using exact alarms. See the official documentation about these changes [here](https://developer.android.com/about/versions/14/changes/schedule-exact-alarms). This change addresses issue [1906](https://github.com/MaikuB/flutter_local_notifications/issues/1906)

+Note that the plugin uses Android Gradle plugin 7.3.1 to leverage this functionality so to errr on the safe side, applications should aim to use the same version at a **minimum**. Using a higher version is also needed as at point, Android Studio bundled a newer version of the Java SDK that will only work with Gradle 7.3 or higher (see [here](https://docs.flutter.dev/release/breaking-changes/android-java-gradle-migration-guide) for more details).
