Answer 1

It may be because of wrong(unextisted) notification icon. Check it and maybe use it from another folder.
I think you already added this line to your code, but I have to mention(Use it when the app starts):
WidgetsFlutterBinding.ensureInitialized();
Also, have you added this to your manifest?
<receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver" />
<receiver android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.MY_PACKAGE_REPLACED"/>
</intent-filter>
</receiver>
