                        repositories {  
                           maven {  
                                 url ""  
  • Next, add the following dependencies in the app/build.gradle file.

                      android { 
                      packagingOptions { 
                      exclude 'META-INF/AL2.0' 
                      exclude 'META-INF/DEPENDENCIES' 
                      exclude 'META-INF/LICENSE' 
                      exclude 'META-INF/LICENSE.txt' 
                      exclude 'META-INF/license.txt' 
                      exclude 'META-INF/NOTICE' 
                      exclude 'META-INF/NOTICE.txt' 
                      exclude 'META-INF/notice.txt'

4) Initialization of MirrorFly Plugin

  • Add the following code in the main function of your main.dart file, before runApp()

                   void main() {  
                         licenseKey: LICENSE_KEY,  
                         iOSContainerID: iOS_APP_GROUP_ID,  
                         chatHistoryEnable: ENABLE_CHAT_HISTORY);  
                      runApp(const MyApp());  

5) Register A User

  • To register a user in the Sandbox/ Live mode, include the below code:

                   Mirrorfly.registerUser(userIdentifier).then((value) {  
                   // you will get the user registration response  
                   var userData = registerModelFromJson(value);  
                   }).catchError((error) {  
                      // Register user failed print throwable to find the exception details.  

6) Send 1:1 Message

  • You can use the below method to enable sending of messages.

                   var userJid = await Mirrorfly.getJid(username);  

                   Mirrorfly.sendTextMessage(message, jid).then((value) {  
                      // you will get the message sent success response  
                      var chatMessage = sendMessageModelFromJson(value);

  • Use the below code to enable reception of messages.

                      // you will get the new messages
