could not build Objective-C module 'flutter_freshchat'(Not able to take iOS build)

[Sunsiha]

In one of my project Iam using flutter_freshchat integration. In that am facing an issue in iOS, when I add flutter_freshchat: ^1.3.0 in pubspec.yaml. Am not able to build only with this. Am getting error the following;

<module-includes>:1:9: note: in file included from <module-includes>:1:#import "Headers/flutter_freshchat-umbrella.h" ^/Users/docty/Workspace/Projects/Docty/ios/Pods/Target Support Files/flutter_freshchat/flutter_freshchat-umbrella.h:13:9: note: in file included from /Users/docty/Workspace/Projects/Docty/ios/Pods/Target Support Files/flutter_freshchat/flutter_freshchat-umbrella.h:13:#import "FlutterFreshchatPlugin.h" ^/Users/docty/Workspace/FlutterDevelopments/flutter/.pub-cache/git/flutter_freshchat-37d8d569f7adc8c6451384634386f1151b1d686f/ios/Classes/FlutterFreshchatPlugin.h:2:9: error: include of non-modular header inside framework module 'flutter_freshchat.FlutterFreshchatPlugin': '/Users/docty/Workspace/Projects/Docty/ios/Pods/FreshchatSDK/FreshchatSDK/FreshchatSDK.h'#import "FreshchatSDK.h" ^<unknown>:0: error: could not build Objective-C module 'flutter_freshchat'

But when I use the workaround like the following link I am able to build.
#33

That time I have to remove the domain from FlutterFreshchat.init. But without a domain it's not loading the data also. May I know why I am getting this kind of issue. Struggling from past one week. I tried all the git issues solution. It's not working.
