Quickstart

This quickstart shows how to use Dyte's Flutter UI Kit SDK to add live video and audio to your Flutter applications.

For getting started quickly, you can use our sample code. You can clone and run a sample application from the Flutter UI Kit Sample App GitHub repository.

Objective

You’ll learn how to:

• Install the Dyte SDK
• Configuring Android & iOS permissions
• Initialize the SDK
• Configure a Dyte meeting
• Launch the meeting UI

Before Getting Started

Make sure you've read the Getting Started with Dyte topic and completed the steps in the Integrate Dyte section. You must complete the following steps:

• Create a Dyte Developer Account
• Create Presets
• Create a Dyte Meeting
• Add Participant to the meeting

Step 1: Install the SDK

Install the SDK from pub.dev.

flutter pub add dyte_uikit

Step 2: Configure permissions for Android and iOS

Perform the following steps:

Android

Set compileSdkVersion 33 and minSdkVersion 21 inside build.gradle file at the <project root>/android/app/build.gradle file.

  defaultConfig {
        ...

        compileSdkVersion 33
        minSdkVersion 21

        ...
    }

And change the kotlin version to 1.9.0

    ext.kotlin_version = '1.9.0'

iOS

1. Set minimum deployment target for your Flutter app to 13.0 or higher.

platform :ios, '13.0'

2. Add the following keys to your Info.plist file, located in <project root>/ios/Runner/Info.plist :

/* Attach the permission to use camera & microphone. */
<key>NSBluetoothPeripheralUsageDescription</key>
<string>We will use your Bluetooth to access your Bluetooth headphones.</string>

<key>NSBluetoothAlwaysUsageDescription</key>
<string>We will use your Bluetooth to access your Bluetooth headphones.</string>

<key>NSCameraUsageDescription</key>
<string>For people to see you during meetings, we need access to your camera.</string>

<key>NSMicrophoneUsageDescription</key>
<string>For people to hear you during meetings, we need access to your microphone.</string>

<key>NSPhotoLibraryUsageDescription</key>
<string>For people to share, we need access to your photos.</string>

3. In iOS, if you are allowing user to download attachments in chat, add the following permissions in your app's Info.plist:

<key>LSSupportsOpeningDocumentsInPlace</key>
<true/>
<key>UIFileSharingEnabled</key>
<true/>

Step 3: Configure a Dyte meeting

To initiate Dyte Meeting for any participant you just need to pass authToken as an argument. You can get the authToken via the Add Participant API.

After getting the authToken, you need to create the DyteMeetingInfoV2 object as follows:

Name	Description
authToken	After you've created the meeting, add each participant to the meeting using the Add Participant API (The presetName created earlier must be passed in the body of the Add Participant API request) The API response contains the authToken.
baseUrl	The base URL of the Dyte server. Default value is https://api.dyte.io/v2. This is an optional argument.
enableAudio	A boolean value to enable or disable audio in the meeting. Default value is true. This is an optional argument.
enableVideo	A boolean value to enable or disable video in the meeting. Default value is true. This is an optional argument.

final meetingInfo = DyteMeetingInfoV2(
                    authToken: '<authToken>',
                    baseUrl: 'https://api.dyte.io/v2',      // optional argument, if you want to pass your own baseUrl
                    enableAudio: false,                     // optional argument, to enable or disable audio in the meeting
                    enableVideo: false,                     // optional argument, to enable or disable video in the meeting
                  );

Step 4: Initialize the SDK

The DyteUIKit is the main class of the SDK. It is the entry point and the only class required to initialize Dyte UI Kit SDK. To initialize it we have to pass DyteUIKitInfo object as an argument.

/* Passing the DyteMeetingInfoV2 object `meetingInfo` you created in the Step 3,
*/

final uikitInfo = DyteUIKitInfo(
      meetingInfo,
      // Optional: Pass the DyteDesignTokens object to customize the UI
      designToken: DyteDesignTokens(
        colorToken: DyteColorToken(
          brandColor: Colors.purple,
          backgroundColor: Colors.black,
          textOnBackground: Colors.white,
          textOnBrand: Colors.white,
        ),
      ),
    );

final uiKit = DyteUIKitBuilder.build(uiKitInfo: uikitInfo, context: context);

You can learn more about customization of the uikit in the Design System section.

Step 5: Launch the meeting UI

To launch the meeting you can simply use the object returned after calling build method. The uikit above is a widget itself. You can push this widget as a page to start the flow of prebuilt Flutter UI Kit.

import 'package:dyte_uikit/dyte_uikit.dart';
import 'package:flutter/material.dart';

class DyteMeetingPage extends StatelessWidget {
  const DyteMeetingPage({super.key});

  @override
  Widget build(BuildContext context) {
    ...
    // Push this widget as page in your app
    // Earlier it was uikit.loadUI() which is now deprecated,just use uikit.
    return uiKit;
  }
}

Voila! You're all done. Here is the pictorial representation of all the configuration options passed.
