Get your Application Id #
Sign up for Kommunicate to get your APP_ID. This APP_ID is used to create/launch conversations.
Launch chat #
Kommunicate provides buildConversation function to create and launch chat directly saving you the extra steps of authentication, creation, initialization and launch. You can customize the process by building the conversationObject according to your requirements.
To launch the chat you need to create a conversation object. This object is passed to the buildConversation function and based on the parameters of the object the chat is created/launched.
Below are some examples to launch chat in different scenarios:
Launching chat for visitor: #
If you would like to launch the chat directly without the visiting user entering any details, then use the method as below:
try {
dynamic conversationObject = {
'appId': '<APP_ID>' // The [APP_ID](https://dashboard.kommunicate.io/settings/install) obtained from kommunicate dashboard.
};
dynamic result = await KommunicateFlutterPlugin.buildConversation(conversationObject);
print("Conversation builder success : " + result.toString());
} on Exception catch (e) {
print("Conversation builder error occurred : " + e.toString());
}

Launching chat for visitor with lead collection: #
If you need the user to fill in details like phone number, emailId and name before starting the support chat then launch the chat with withPreChat flag as true. In this case you wouldn't need to pass the kmUser. A screen would open up for the user asking for details like emailId, phone number and name. Once the user fills the valid details (atleast emailId or phone number is required), the chat would be launched. Use the function as below:
try {
dynamic conversationObject = {
'appId': '<APP_ID>',// The [APP_ID](https://dashboard.kommunicate.io/settings/install) obtained from kommunicate dashboard.
'withPreChat': true
};
dynamic result = await KommunicateFlutterPlugin.buildConversation(conversationObject);
print("Conversation builder success : " + result.toString());
} on Exception catch (e) {
print("Conversation builder error occurred : " + e.toString());
}
copied to clipboard
Launching chat with existing user: #
If you already have the user details then create a KMUser object using the details and launch the chat. Use the method as below to create KMUser with already existing details:
try {
dynamic user = {
'userId' : '<USER_ID>', //Replace it with the userId of the logged in user
'password' : '<PASSWORD>' //Put password here if user has password, ignore otherwise
};
dynamic conversationObject = {
'appId': '<APP_ID>',// The [APP_ID](https://dashboard.kommunicate.io/settings/install) obtained from kommunicate dashboard.
'kmUser': jsonEncode(user)
};
dynamic result = await KommunicateFlutterPlugin.buildConversation(conversationObject);
print("Conversation builder success : " + result.toString());
} on Exception catch (e) {
print("Conversation builder error occurred : " + e.toString());
}
copied to clipboard

Note: jsonEncode requires the dart package dart:convert. Make sure you have imported the package at the top of the dart file as import 'dart:convert';

If you have a different use-case and would like to customize the chat creation, user creation and chat launch, you can use more parameters in the conversationObject.
Below are all the parameters you can use to customize the conversation according to your requirements:

Parameter
Type
Description

appId
String
The APP_ID obtained from kommunicate dashboard

groupName
String
Optional, you can pass a group name or ignore

kmUser
KMUser
Optional, Pass the details if you have the user details, ignore otherwise. The details you pass here are used only the first time, to login the user. These login details persists until the app is uninstalled or you call logout.

withPreChat
boolean
Optional, Pass true if you would like the user to fill the details before starting the chat. If you have user details then you can pass false or ignore.

isSingleConversation
boolean
Optional, Pass true if you would like to create only one conversation for every user. The next time user starts the chat the same conversation would open, false if you would like to create a new conversation everytime the user starts the chat. True is recommended for single chat

metadata
dynamic
Optional. This metadata if set will be sent with all the messages sent from that device. Also this metadata will be set to the conversations created from that device.

agentIds
List
Optional, Pass the list of agents you want to add in this conversation. The agent ID is the email ID with which your agent is registered on Kommunicate. You may use this to add agents to the conversation while creating the conversation. Note that, conversation assignment will be done on the basis of the routing rules set in the Conversation Rules section. Adding agent ID here will only add the agents to the conversation and will not alter the routing rules.

botIds
List
Optional, Pass the list of bots you want to add in this conversation. Go to bots -> Manage Bots -> Copy botID . Ignore if you haven't integrated any bots. You may use this to add any number of bots to the conversation while creating the conversation. Note that this has no effect on the conversation assignee, as the Conversation Rules set forth in the Dashboard will prevail.

createOnly
boolean
Optional. Pass true if you need to create the conversation and not launch it. In this case you will receive the clientChannelKey of the created conversation in the success callback function.

Send data to bot platform #
You can set the data you want to send to the bot platform by calling the updateChatContext method as below:
dynamic chatContext = {
'key': 'value',
'objKey': {
'objKey1' : 'objValue1',
'objKey2' : 'objValue2'
}
};

KommunicateFlutterPlugin.updateChatContext(chatContext);

Update logged in user's details #
You can update some details of the logged in user like displayName, imageUrl, metadata etc. Use the updateUserDetail method as below (Remove the fields from the userDetails object below, which you don't want to update):
try {
dynamic userDetails = {
'displayName': '<New Name>',
'imageLink': '<new-image-url>',
'email': '<New-Email>',
'contactNumber': '<New-Contact-Number>'
'metadata': {
'objKey1' : 'objValue1',
'objKey2' : 'objValue2'
}
};

KommunicateFlutterPlugin.updateUserDetail(userDetails);
} on Exception catch (e) {
print("Error occured while updating userDetails : " + e.toString());
}
copied to clipboard
Note: userIdis a unique identifier of a kmUser object. It cannot be updated.
Logout #
You can call the logout method to logout the user from kommunicate. Use the method as below:
KommunicateFlutterPlugin.logout();

Dialogflow chatbot integration in your Flutter app #
Dialogflow is a Google-owned NLP platform to facilitate human-computer interactions such as chatbots, voice bots, etc.
Kommunicate's Dialogflow integration provides a more versatile, customizable and better chatting experience. Kommunicate Flutter Live Chat SDK supports all of Dialogflow's features such as Google Assistant, Rich Messaging, etc. On top of that, it is equipped with advanced features such as bot-human handoff, conversation managing dashboard, reporting, and others.
You can connect your Dialogflow chatbot with Kommunicate in the following 3 simple steps. Here is a step by step blog to add Kommunicate SDK in your Flutter app.
Step 1: Get your API credentials from Dialogflow #

Login to Dialogflow console and select your agent from the dropdown in the left panel.
Click on the settings button. It will open a setting page for the agent.
Inside the general tab search for GOOGLE PROJECTS and click on your service account.
After getting redirected to your SERVICE ACCOUNT, create a key in JSON format for your project from the actions section and it will get automatically downloaded.

Step 2: Create a free Kommunicate account #
Create a free account on Kommunicate and navigate to the Bots section.
Step 3: Integrate your Dialogflow chatbot with Kommunicate #

In the Bot integrations section, choose Dialogflow. A popup window will open.
Upload your Key file here and proceed.
Give a name and image to your chatbot. It will be visible to the users chatting with your chatbot.
Enable/Disable chatbot to human handoff. If enabled, it will automatically assign conversations to humans in case the chatbot is not able to answer.

Step 4: Install the Kommunicate Flutter SDK to your app #
You can add the Kommunicate SDK in your Flutter app easily. More information on how to integrate with your Flutter app here.
