Flutter - not able to run in android device

Hi I am getting this error while run without debugging my project in android device.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> Could not resolve all artifacts for configuration ':app:debugCompileClasspath'.
   > Failed to transform artifact 'arm64_v8a_debug.jar (io.flutter:arm64_v8a_debug:1.0.0-c8e3b9485386425213e2973126d6f57e7ed83c54)' to match attributes

I used connectivity plugin in my code, and error message says that, when I trying to run flutter build apk

Note: C:\Users\Admin\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\connectivity-0.4.9\android\src\main\java\io\flutter\plugins\connectivity\ConnectivityBroadcastReceiver.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

Can someone help me with this? Thanks in advance.

Update : I am able to run it in samsung j7, but I am getting the above error in samsung a7

Code I used to check connectivity

import 'package:connectivity/connectivity.dart';
import 'package:flutter/material.dart';
import 'dart:io';
class NetworkConnection{
  Future<String> checkInternetConnectivity(BuildContext context) async
  {
    var result = await Connectivity().checkConnectivity();
    String connection = "unknown";
    if(result == ConnectivityResult.none)
    {    
      //_showToast(context,"No Connectivity");
      connection =  "not connected";
    }
    else if(result == ConnectivityResult.mobile)
    {
      try {
            final result = await InternetAddress.lookup('google.com');
            if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
              connection =  "connected";
            }
          } on SocketException catch (_) {
            connection =  "not connected";
          }

      //_showToast(context,"Connected to mobile");

    }
    else if(result == ConnectivityResult.wifi)
    {
      try {
            final result = await InternetAddress.lookup('google.com');
            if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
              connection = "connected";
            }
          } on SocketException catch (_) {
            connection =  "not connected";
          }
      //_showToast(context,"Connected to wifi");
    
    }
    return connection;
  }
}
