[Piyush-e7]

Describe the bug
I have implemented appsflyer_sdk: ^6.14.2. I have done all configurations as per the documentation link below.
Link: https://github.com/AppsFlyerSDK/appsflyer-flutter-plugin/blob/master/doc/BasicIntegration.md

Code Implementation

AppsflyerSdk? _appsflyerSdk;

// SDK Options
final AppsFlyerOptions options = AppsFlyerOptions(
      afDevKey: AppConfig.appsflyerSdkDevKey,
      appId: AppConfig.appsflyerSdkAppID,
      showDebug: true,
      timeToWaitForATTUserAuthorization: 15,
      manualStart: true,
);
_appsflyerSdk = AppsflyerSdk(options);`

// Initialization of the AppsFlyer SDK
 await _appsflyerSdk?.initSdk(
      registerConversionDataCallback: true,
      registerOnAppOpenAttributionCallback: true,
      registerOnDeepLinkingCallback: true,
 );

// Starting the SDK
 _appsflyerSdk?.startSDK(
      onSuccess: () {
        CommonUtils.printWrapped(
          "Analytics AppsFlyer SDK initialized successfully",
        );
      },
      onError: (int errorCode, String errorMessage) {
        CommonUtils.printWrapped(
          "Error initializing AppsFlyer SDK: Code $errorCode - $errorMessage",
        );
      },
);
