This issue doesn't seem to happen on cloud_firestore: ^3.1.7. Try updating the cloud_firestore version that you're using. If that doesn't work, see if proguard is enabled on your Android build. Updating android.enableR8=false the Android build's gradle.properties also works to some.

I was trying to connect my application to bluetooth devices (which is ESP32) using flutter_blue_plus library. So in ESP32, there is a firmware that advertize bluetooth signal and my application should connect to that device when I press "CONNECT" button.
Here is the code for my connect button :
onPressed: () {
flutterBlue.startScan(timeout: Duration(seconds: 4));
var subscription = flutterBlue.scanResults.listen((results) async {
for (ScanResult r in results) {
print('${r.device.name} found! rssi: ${r.rssi}');
if (_id_controller.text == '${r.device.name}' && _id_controller.text != '') {
flutterBlue.stopScan();
r.device.connect();
print('${_id_controller.text} same with ${r.device.name}');
print(flutterBlue.connectedDevices);
List<BluetoothService> services = await r.device.discoverServices();
services.forEach((service) async {
var characteristics = service.characteristics;
for(BluetoothCharacteristic c in characteristics) {
List<int> value = await c.read();
print(value);
await c.write([73, 77, 65, 77]);
}
});
}
}
});
flutterBlue.stopScan();
},
so there after I press that "CONNECT" button, it is not trying to discover the services. After doing the debug processing, it said that my apps is not connected at all. Here is the dlog for my debug result.

I think there is an issue at my "CONNECT" button. But I am not really sure. Here is the full code. Really need help for this. Thanks.
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 :

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()
i got this problem with all libraries

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.

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:

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.
