Initialize MirrorFly Plugin#

To initialize the plugin, place the below code in your main.dart file inside main function before runApp().

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

Chat init Function Description#

FunctionParameter TypeDescription
LICENSE_KEYStringLicense key is required to proceed with registration
iOS_APP_GROUP_IDStringCreate App groups and assign the obtained group container id. Plugin uses this string to create the path for the local storage.
ENABLE_CHAT_HISTORYbooltrue To enable chat history and false for normal chat, default false

Note : The chat history feature allows us to retrieve chat history every time you log into the newly acquired device. The feature stores chat history securely and provides access to the users whenever they need it. This ensures that users can access the same conversation thread across devices without any data loss.


The base URL must have the Http/Https protocol which must be closed with a ‘slash (/)’, if not an exception - a bug message will pop up.


Use the below method to register a user in sandbox Live mode.

Unless you log out the session, make a note that should never call the registration method more than once in an application

Note: While registration, the below registerUser method will accept the FCM_TOKEN as an optional param and pass it across. The connection will be established automatically upon completion of registration and not required for seperate login.

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.
userIdentifierStringA unique Id to Register the User. We accept only the AlphaNumeric String
tokenStringA registration token that is generated by FCM Plugin for the user's app instance to send message for free
isForceRegisterBooleandefault value true, provide true to force the logout of the old session if the registered user has reached the maximum no of multi-sessions or provide false to allow registration till the maximum no of multi-sessions

Note : After registering, make sure to update the profile of the registered user Update Profile.

Note : You need to re-login when the onLoggedOut event is triggered.

Note : It is recommended to disallow users to backup an app if it contains sensitive data. Having access to backup files (i.e. when android:allowBackup="true"), it is possible to modify/read the content of an app even on a non-rooted device.


If FORCE_REGISTER is false and it reached the maximum no of multi-sessions then registration will not succeed it will throw a 405 exception, Either FORCE_REGISTER should be true or one of the existing session need to be logged out to continue registration.


Some of the most common terminologies used in MirrorFly Plugin with description

userID/userBareIDUnique Id to Register the User. User identifiers can only contain lowercase alphanumeric characters, (-) hyphens, and (_) underscores.
userJid (or) JIDuserID+@+domain of the chat server Ex. 12345678@xmpp.chatsystem.dev.contus.us

Plugin will have built-in functions to prepare the JID, Group JID, and more.
