[flutter/FCM]problem receiving notification

I'm using flutter and Firebasemessaging to send and receive notification and the plugging FlutterLocalNotifications to display them.
but when I receive the notification I get the error :
D/FLTFireMsgReceiver(23943): broadcast received for message

The solution is that I need to add the icon path when I set AndroidNotificationDetails.
static Future _notificationDetails() async {
return NotificationDetails(
android: AndroidNotificationDetails('channel id', 'channel name',
channelDescription: 'channel description',
importance: Importance.max,
==> icon: "#mipmap/ic_launcher"), <==
iOS: IOSNotificationDetails(),
);
}

just add icon parameter to AndroidNotificationDetails()

flutter firebase offline error caused by sending get request to real time database

im currently trying to use flutter and firebase realtime database together but i keep on getting this error whenever i try and get or update the database. it was working fine a few days ago but i accidently rolled back the changes.
i have done
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(
name: "main_app",
options: FirebaseOptions(
apiKey: "XXXXXXXXXXXXXXXXXXXXXXXX",
authDomain: "fXXXXXXXXXXXXX",
databaseURL: "XXXXXXXXXXXXXXX",
projectId: "XXXXXXXXXXXXXXXXX",
storageBucket: "XXXXXXXXXXXXXX",
messagingSenderId: "XXXXXXXXXX",
appId: "XXXXXXXXXXXXXXXXXXXXX",
measurementId: "XXXXX"
)
);
the error occurs wheneever i do
FirebaseDatabase.instance.ref("/users").get()
i have tried different end points to check if that is the problem but the error is hard to understand imo

You seem to be calling get(), while you're offline and with no data in the cache.
Keep in mind you have to explicitly enable disk persistence for the Firebase Realtime Database before it can read data from it while you're offline. You can do this by calling setPersistenceEnabled(true) at the start of the app, before calling any methods that read/write data:
FirebaseDatabase.instance.setPersistenceEnabled(true);

What I did and it worked for me. Just
flutter pub clean.
uninstall the app on your device.
flutter pub get

After adding library, you should stop session and run app again to successfully import plugins to your app. Plugins need to install when app is generated.

Flutter app crashing on android 10 & R with No static method isAtLeastR

I've seen a few issues similar on Stack overflow, but not one that quite relates to the same libraries.
I'm trying to use 2 plugins in flutter
flutter_geofence and geolocator
They've both been working fine, but since yesterday as soon as of the location play services are called I'm getting the app quit with a stack trace similar to below:
E/flutter (11478): [ERROR:flutter/shell/platform/android/platform_view_android_jni.cc(39)] java.lang.NoSuchMethodError: No static method isAtLeastR()Z in class Landroidx/core/os/BuildCompat; or its super classes (declaration of 'androidx.core.os.BuildCompat' appears in /data/app/com.mypossibleself.app-FTu9V5QDAKR_ngQmuPzg7Q==/base.apk!classes2.dex)

So it's complaining about a missing method isAtLeastR
Other references I've seen to this mention specific versions of com.google.android.gms:play-services-base causing this, but that it's fixed in com.google.android.gms:play-services-base:17.2.1
Neither of these library implement that package in their build.gradle files so I'm at a loss as to what needs doing to fix this issue.

In the app/build.gradle add com.google.android.gms:play-services-base:17.2.1 this should make libraries use specific version of play-services.
If it doesn't help, might need to
configurations.all {
resolutionStrategy {
force 'com.google.needed_dependency'
}
}
https://flutter.dev/docs/development/packages-and-plugins/using-packages#conflict-resolution
Edit as per Andrews suggestion:
17.2.1 doesn't work, but 17.0.0 does.
implementation("com.google.android.gms:play-services-base:17.0.0"){ force = true }

resolutionStrategy {
force 'com.google.android.gms:play-services-base:17.1.0'
}
}
This is what solved it for me.
