FYI, When tried building with connectivity_plus-6.0.5 its building properly with no issues.

Is per chance your app project still in obj-c and not swift?

https://github.com/fluttercommunity/plus_plugins/pull/3173/files#r1713480016

[miquelbeltran]

Mmmhh I cannot reproduce it either with an ios objc project, I did the following:

flutter create -i objc --empty test_ios
flutter pub add connectivity_plus
open ios/Runner.xcworkspace (to fix provisioning profile)
flutter build ios

Compilation worked:

Same result when creating a swift project.

Can you do the same and see if it builds for you?

I got similar issue with connectivity_plus-6.1.0

Error (Xcode): 'ConnectivityPlusPlugin' has different definitions in different modules; first difference is definition in module 'connectivity_plus.Swift'
found 2 referenced protocols
/Users/Documents/test-project/app/build/ios/Production-Release-iphoneos/connectivity_plus/connectivity_plus.framework/Headers
/connectivity_plus-Swift.h:310:11


Modules Issue (Xcode): Definition of 'ConnectivityPlusPlugin' must be imported from module 'connectivity_plus.Swift' before it is required
/Users/Documents/test-project/ios/Runner/GeneratedPluginRegistrant.m:167:3


Encountered error while building for device.

However, this problem does not occur in connectivity_plus-6.0.5.

This is AppDelegate.swift

import UIKit
import Flutter
import GoogleMaps
import flutter_local_notifications

@main
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    // This is required to make any communication available in the action isolate.
    FlutterLocalNotificationsPlugin.setPluginRegistrantCallback { (registry) in
      GeneratedPluginRegistrant.register(with: registry)
    }
    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }
    //Google Maps API Key
    GMSServices.provideAPIKey("")
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
  // for the OneSignal package
  override func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
      super.userNotificationCenter(center, willPresent: notification, withCompletionHandler: completionHandler)
  }
  override func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
      super.userNotificationCenter(center, didReceive: response, withCompletionHandler: completionHandler)
  }
}

And the project also has a swift code section like this: NotificationService.swift

import UserNotifications

import OneSignalExtension

class NotificationService: UNNotificationServiceExtension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var receivedRequest: UNNotificationRequest!
    var bestAttemptContent: UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.receivedRequest = request
        self.contentHandler = contentHandler
        self.bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

        if let bestAttemptContent = bestAttemptContent {
            /* DEBUGGING: Uncomment the 2 lines below to check this extension is executing
                          Note, this extension only runs when mutable-content is set
                          Setting an attachment or action buttons automatically adds this */
            // print("Running NotificationServiceExtension")
            // bestAttemptContent.body = "[Modified] " + bestAttemptContent.body

            OneSignalExtension.didReceiveNotificationExtensionRequest(self.receivedRequest, with: bestAttemptContent, withContentHandler: self.contentHandler)
        }
    }

    override func serviceExtensionTimeWillExpire() {
        // Called just before the extension will be terminated by the system.
        // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
        if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
            OneSignalExtension.serviceExtensionTimeWillExpireRequest(self.receivedRequest, with: self.bestAttemptContent)
            contentHandler(bestAttemptContent)
        }
    }
}

Do you see this error in debug builds or only release builds?

The only change in 6.1.0 is that it deleted the objc plugin definition, which is not clear for me if it was still necessary: https://github.com/fluttercommunity/plus_plugins/pull/3173/files

Is your project somehow an old codebase?

[FullstackWEB-developer]

@miquelbeltran Thank you for your quick reply.
Sure, this is a project I've been managing for 3 years, but I'm using the latest stable flutter version, and all 28 other packages except connectivity_plus are the latest versions.
Could it be that removing the objc plugin definition is causing conflicts with other packages? Or is it that I have objc in my code base?

However, the Object-C part of my project is only the automatically generated this part

[miquelbeltran]

Could it be that removing the objc plugin definition is causing conflicts with other packages? Or is it that I have objc in my code base?

I think the issue is a combination of old(ish) Flutter native codebase and removing the objc definition, indeed.

A newly created Flutter project with objc doesn't have this issue.

A possible solution can be to revert part of the changes in #3173 but keeping the Swift package support. The problem is that I cannot reproduce the issue on my side, so I'd love if someone who has the problem can try this somehow and submit a PR.

[FullstackWEB-developer]

Thank you for your reply.
Let me try again with new codebase
