  • Does this answer your question? [Flutter: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present\]](https://stackoverflow.com/questions/73373944/flutter-targeting-s-version-31-and-above-requires-that-an-explicit-value-for) – Ivo Sep 08 '22 at 07:22

Try adding this in AndroidManifest.xml. Inside <application> .... </application> tag.

   <receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver"
              android:exported="true">   
    </receiver>

Update:

To explain the issue, from Android 12, for the application components such as Activity, BroadCast Receiver, Service.. one must explicitly add android:exported="" flag in Manifest Component. Source

This can be true or false.

If it is marked as true, other apps/system can start the particular component via Intent.

For example, for Launcher Activity we need to mark the activity as android:exported="true" . So that system launcher/ other launcher apps can start application by Intent calling the launcher activity.

In most cases, it wont be necessary to mark it as true.

In this case, adding exported = false also will work. So it is recommended to make it as false.

   <receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver"
              android:exported="false">   
    </receiver>

Actually these changee for Android 12 flutter_local_notifications plugin as already added and fix is available on latest versions.

But when you add the package via flutter pub add flutter_local_notifications, it is only adding old version of the plugin. In my case it was downloading version 8.2.0 , but latest available version is 13.0.0 at the time of writing the answer. So when I explicitly made it to 13.0.0, this issue won't come.

The reason for flutter adding an older version might be the dependency of other packages.

So finally , to conclude, making flutter_local_notifications: ^13.0.0 explicitly in pubspec.yaml will solve this issue.

          android:exported="true">   
</receiver>
