Flutter iOS SDK integration process

To integrate Flutter iOS SDK with your iOS mobile app, please follow the below mentioned steps:

Update your plist

The iOS SDK uses the camera and photo library in iOS.

If your app does not already request permissions for these features, you should update your info.plist file with a usage description for NSPhotoLibraryUsageDescription and NSCameraUsageDescription.

/* You can do this by adding the following lines in your plist source code */
<key>NSPhotoLibraryUsageDescription</key>
<string><description to use photo library></string>
<key>NSCameraUsageDescription</key>
<string><description to use camera></string>
<key>NSAppTransportSecurity</key>        <dict>
<key>NSAllowsArbitraryLoads</key>
<true/></dict>
<key>NSMicrophoneUsageDescription</key>
<string><Add your description here></string>

Update Appdelegate.swift

1. Add import Flutter and import ReveChatSDK at the beginning of your file

2. Write bellow code in didFinishLaunchingWithOptions function

// Some code
let flutterVC = FlutterViewController()
let navVC = UINavigationController(rootViewController: flutterVC)
self.window?.rootViewController = navVC
navVC.navigationBar.isHidden = true
let batteryChannel = FlutterMethodChannel(name: "com.revechat.sdk/sdkchannel",
                                                binaryMessenger: flutterVC.binaryMessenger)

batteryChannel.setMethodCallHandler({
          (call: FlutterMethodCall, result: @escaping FlutterResult) -> Void in
          let reveChatManager = ReveChatManager()
          reveChatManager.setupAccount(with: "account_number") // put your account_number here
          
          switch call.method {
          case "StartREVEChat":
              print("success")
              
              guard let args = call.arguments as? [String:String] else {
                  print("failed fetching")
                  return
              }
let name = args["name"]!
              let email = args["email"]!
              let phone = args["phone"]!
              
              reveChatManager.initiateReveChat(with: name,
                                               visitorEmail: email,
                                               visitorMobile: phone,
                                               onNavigationViewController: flutterVC.navigationController)
              break
          default:
              break
          }          
      })

Update main.dart

1. Write startActivity function as like bellow

Future<void> _startActivity() async {
    try {
      const platform = MethodChannel('com.revechat.sdk/sdkchannel');
      
      final String result = await platform.invokeMethod('StartREVEChat',{
        'email':'[e-mail]', // put your email here
        'name':'netzaintest', //put your name here
        'phone':'01409404444', //put your mobile number her
      });

      debugPrint('Result: $result ');
    } on PlatformException catch (e) {
      debugPrint("Error: '${e.message}'.");
    }
}

1. Call this start activity from a button action

floatingActionButton: FloatingActionButton(
        onPressed: _startActivity,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
 )

Method name : “sceneDidBecomeActive” or “applicationDidBecomeActive”
self.endBackgroundUpdateTask()



Method name “sceneWillResignActive” or “applicationWillResignActive”
self.backgroundUpdateTask = UIApplication.shared.beginBackgroundTask(expirationHandler: {
                self.endBackgroundUpdateTask()
            })


func endBackgroundUpdateTask() {
        UIApplication.shared.endBackgroundTask(self.backgroundUpdateTask)
        self.backgroundUpdateTask = UIBackgroundTaskIdentifier.invalid
    }

FAQs (General issues faced while integrating)

1. I am facing the following error in console ld: library not found for -lAFNetworking Reason: in your pod file use_frameworks! line is commented. Solution: Uncomment use_frameworks! line and build again

2. Getting Crash when initiating revechat sdk reason: the pod has been updated on the cocoa pods solution: run ‘pod update‘ in the terminal on your project path
