@MilenaSousa does your ios uses swift or objective-c? also, try this below steps:

1. Bridging Header must be created.
   Open the project with XCode. Then choose File -> New -> File -> Swift File.
   A dialog will be displayed when creating the swift file(Since this file is deleted, any name can be used.).
   XCode will ask you if you wish to create Bridging Header, click yes.
2. Make sure you have use_frameworks! in the Runner block, in ios/Podfile。
3. Make sure you have SWIFT_VERSION 4.2 selected in you XCode -> Build Settings
4. Do flutter clean.
5. Go to your ios folder, delete Podfile.lock and Pods folder and then execute pod install --repo-update

I researched the problem and it is something that happens with all Flutter plugins, take a look at this flutter/flutter#25676.

The above steps should resolve this issue.

@MilenaSousa I think I know where the problem might be, but wanted to ask you what are you updating user info? if so are you providing customProperties to Freshchat. The reason is that I looked through the code and I forgot to check if a customProperies is passed or not so if it is not passed it will crash the plugin.

Anyway, I think the initial issue is resolved this is related to something ios side of the plugin.

[MilenaSousa]

I wasn't adding the customProperies yet

After i added half the errors disappeared, but there are still some

I added this to initState:
FreshchatUser user = FreshchatUser.initail();
user.email = "jhon@test.com";
user.firstName = "jhon";
user.lastName = "doe";
user.phoneCountryCode = "+91";
user.phone = "0123456789";

Map<String, String> customProperties = Map<String, String>();
customProperties["loggedIn"] = "true";

await FlutterFreshchat.updateUserInfo(user: user, customProperties: customProperties);

The mistakes now are these

@MilenaSousa updated the plugin to 1.1.6 try this latest version should fix the problem you have

@MilenaSousa I don't have a mac so I really can't debug the code myself, and I am just making changes based on the errors that you are providing me with, anyway just made a few changes and updated the library to 1.1.7 you should check it. I am going to close this issue as the original purpose of this issue is completed If this doesn't work create a new issue.
Hope this helps.
