package not exist ,named parameter not defined

When I run flutter I get the error as below, it says package doesn't exist, named parameter not defined like error. Even though I downgraded and upgraded flutter it is showing the same error please look and tell whether if any fixes available.
The plugins `firebase_auth, flutter_country_picker, geocoder` use a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

Flutter no longer builds in ios or android after using firebase realtime

Problem
I have been successfully using firebase firestore in my current app for months. However, recently when experimenting with firebase realtime, when I attempt to build on either physical or emulated iphone or android, the build fails.
I've tried usual - flutter clean, multiple emulators, reboot everything, same errors.
Strangely, when building with a pre-realtime version, the errors persist - none of my previous commits work anymore!
For sanity check, I created a new flutter application to see if anything was working - yes, a new clean flutter app works.
Any advice?

It seems your Image size is not correctly defined. Use BoxFit widget to adjust the same. Try the link
https://medium.com/flutter-community/how-to-use-images-in-flutter-to-the-point-5542b4412a53
Are you Converting Base64 to decode Image ? then you should follow this then your Problem will be solved.
import 'dart:convert';
import 'package:image/image.dart' as ImageProcess;
final _byteImage = Base64Decoder().convert(base64Image);
Widget image = Image.memory(_byteImage)
