Getting Started

This section will guide users through the initial setup and installation of the Flutter package.

Installation

Instructions on how to install the package using Flutter.

flutter pub add mediasfu_sdk

iOS Setup:

1. Minimum iOS Platform Version:

   • Navigate to your ios/Podfile located in your project's iOS directory.

   • Find the line specifying the iOS platform version.

   • Update the minimum iOS platform version to 12.0:

     platform :ios, "12.0"
     

2. Info.plist Updates:

   • Open your Info.plist file located at <project root>/ios/Runner/Info.plist.

   • Add the following entries to allow camera and microphone usage:

     <key>NSCameraUsageDescription</key>
     <string>$(PRODUCT_NAME) Camera Usage!</string>
     <key>NSMicrophoneUsageDescription</key>
     <string>$(PRODUCT_NAME) Microphone Usage!</string>
     

macOS Setup:

1. Minimum macOS Version:

   • Navigate to your macos/Podfile located in your project's macOS directory.

   • Find the line specifying the macOS platform version.

   • Update the minimum macOS platform version to match your requirements. For example, to support macOS 10.15 (Catalina) and above:

     platform :osx, '10.15'
     

2. Info.plist Updates:

   • Open your macos/Runner/Info.plist file located at <project root>/macos/Runner/Info.plist.

   • Add the following entries to allow camera and microphone usage:

     <key>NSCameraUsageDescription</key>
     <string>$(PRODUCT_NAME) Camera Usage!</string>
     <key>NSMicrophoneUsageDescription</key>
     <string>$(PRODUCT_NAME) Microphone Usage!</string>
     

3. Entitlements Configuration:

   • Create a new file named Release.entitlements in your macos/Runner directory if it doesn't already exist.

   • Add the following entries to Release.entitlements to allow your app to access the camera, microphone, and open outgoing network connections:

     <key>com.apple.security.network.server</key>
     <true/>
     <key>com.apple.security.network.client</key>
     <true/>
     <key>com.apple.security.device.camera</key>
     <true/>
     <key>com.apple.security.device.microphone</key>
     <true/>
     

Android Setup:

1. SDK Version Updates:

   • Open the build.gradle file located at <project root>/android/app/build.gradle.
   • Update the following SDK versions if necessary:
     • minSdkVersion: Specifies the minimum Android API level required by your app.
     • compileSdkVersion: Specifies the version of the SDK against which you compile your app.
     • targetSdkVersion: Specifies the API level that your app targets.

     android {
         //...
         defaultConfig {
             minSdkVersion 23
             compileSdkVersion 31
             targetSdkVersion 31
             // Other configurations...
         }
     }
     

2. AndroidManifest Permissions:

   • Open the AndroidManifest.xml file located at <project root>/android/app/src/main/AndroidManifest.xml.

   • Ensure the following permissions are present to allow camera, microphone, and network access:

     <uses-feature android:name="android.hardware.camera" />
     <uses-feature android:name="android.hardware.camera.autofocus" />
     <uses-permission android:name="android.permission.INTERNET"/>
     <uses-permission android:name="android.permission.CAMERA" />
     <uses-permission android:name="android.permission.RECORD_AUDIO" />
     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
     <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
     <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
     <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
     <uses-permission android:name="android.permission.WAKE_LOCK" />
     

   • If your app requires Bluetooth functionality, add these permissions:

     <uses-permission android:name="android.permission.BLUETOOTH" />
     <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
     

3. Java 8 Compatibility:

   • Ensure your app is compatible with Java 8 by adding the following code block to the android section of your build.gradle:

   • android {
         //...
         compileOptions {
             sourceCompatibility JavaVersion.VERSION_1_8
             targetCompatibility JavaVersion.VERSION_1_8
         }
     }
     

By following these steps, you ensure that your Flutter app has the necessary permissions and configurations for camera, microphone, and network access on both iOS and Android platforms.

Basic Usage Guide

A basic guide on how to use the package for common tasks.

This section will guide users through the initial setup and installation of the Flutter package.

For the community edition, users can visit the GitHub repository at MediaSFU/MediaSFUOpen.

import 'package:flutter/material.dart';
// Import the prebuilt event room(s)
import 'package:mediasfu_sdk/mediasfu_sdk.dart';


void main() {
  runApp(const MyApp());
}

/// The main application widget for Mediasfu Webinar.
///
/// This application allows users to join or create webinars hosted on Mediasfu.
/// It provides a simple and streamlined experience for users to participate in webinars.
class MyApp extends StatelessWidget {
  /// Constructs a new instance of [MyApp].
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Mediasfu Webinar',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      // Home screen displays the MediasfuWebinar widget
      home: const MediasfuWebinar(),
    );
  }
}

Programmatically Fetching Tokens

If you prefer to fetch the required tokens programmatically without visiting MediaSFU's website, you can use the PreJoinPage component and pass your credentials as props:

// Import the necessary components
import 'package:mediasfu_sdk/mediasfu_sdk.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

/// The main application widget.
class MyApp extends StatelessWidget {
  /// Constructs a new instance of [MyApp].
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    // Define your API credentials
    final credentials = {
      'apiUserName': "yourAPIUserName",
      'apiKey': "yourAPIKey",
    };

    return MaterialApp(
      title: 'Mediasfu Generic',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      // Render the MediasfuGeneric component with PrejoinPage and credentials
      home: MediasfuGeneric(
        PrejoinPage: ({
          required Map<String, dynamic> credentials,
          required Map<String, dynamic> parameters,
        }) {
          return PreJoinPage(credentials: credentials, parameters: parameters);
        },
        credentials: credentials,
      ),
    );
  }
}

Preview of Welcome Page

Preview of Prejoin Page

Custom Welcome/Prejoin Page

Alternatively, you can design your own welcome/prejoin page. The core function of this page is to fetch user tokens from MediaSFU's API and establish a connection with the returned link if valid.

Parameters Passed to Custom Page

MediaSFU passes relevant parameters to the custom welcome/prejoin page:

typedef ShowAlert = void Function({
  required String message,
  required String type,
  required int duration,
});

typedef ConnectSocket = Future<dynamic> Function(
    String apiUserName, String apiKey, String apiToken, String link);
    
  late final ShowAlert showAlert;
  late final Function(bool) updateIsLoadingModalVisible;
  late bool onWeb;
  late final ConnectSocket connectSocket;
  late dynamic socket;
  late Function(dynamic) updateSocket;
  late Function(bool) updateValidated;
  late Function(String) updateApiUserName;
  late Function(String) updateApiToken;
  late Function(String) updateLink;
  late Function(String) updateRoomName;
  late Function(String) updateMember;
  late bool validated;

See the following code for the PreJoinPage page logic:

int maxAttempts =
    20; // Maximum number of unsuccessful attempts before rate limiting
int rateLimitDuration = 3 * 60 * 60 * 1000; // 3 hours in milliseconds
String apiKey = 'yourAPIKEY';
String apiUserName = 'yourAPIUSERNAME';
Map<String, dynamic> userCredentials = {
  'apiUserName': apiUserName,
  'apiKey': apiKey
};

class PreJoinPage extends StatefulWidget {
  final Map<String, dynamic> parameters;
  final Map<String, dynamic> credentials;

  const PreJoinPage(
      {super.key, required this.parameters, required this.credentials});

  @override
  // ignore: library_private_types_in_public_api
  _PreJoinPageState createState() => _PreJoinPageState();
}

class _PreJoinPageState extends State<PreJoinPage> {


  Map<String, dynamic> credentials = userCredentials;

  late final ShowAlert showAlert;

    updateMember = widget.parameters['updateMember'];
    validated = widget.parameters['validated'];
  }

IP Blockage Warning And Local UI Development

Entering the event room without the correct credentials may result in IP blockage, as the page automatically attempts to connect with MediaSFU servers, which rate limit bad requests based on IP address.

If users attempt to enter the event room without valid credentials or tokens, it may lead to IP blockage due to MediaSFU servers' rate limiting mechanism. To avoid unintentional connections to MediaSFU servers during UI development, users can pass the useLocalUIMode parameter as true.

In this mode, the package will operate locally without making requests to MediaSFU servers. However, to render certain UI elements such as messages, participants, requests, etc., users may need to provide seed data. They can achieve this by importing random data generators and passing the generated data to the event room component.

Example for Broadcast Room

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

void main() {
  runApp(const MyApp());
}

// Global credentials used for authentication
final credentials = {
  'apiUserName': "your_api_user_name",
  'apiKey': "your_api_key",
};

/// The main application widget responsible for setting up the UI and navigation.
///
/// Users have the option to use a custom prejoin page or the default prejoin page provided by Mediasfu.
/// Custom prejoin pages require user credentials to create/join an event.
/// If no custom prejoin page is provided, a default welcome page is presented where users can scan their access code
/// obtained from the Mediasfu website.
class MyApp extends StatelessWidget {
  /// Indicates whether to use seed data for generating random participants and messages.
  final bool useSeed = true;

  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    // Name of the member
    const String memberName = 'Alice';

    // Name of the host (same as member if the member is the host)
    const String hostName = 'Fred';

    // Generate random participants with Alice as member and Fred as host
    final participants = useSeed
        ? generateRandomParticipants(memberName, '', hostName,
            forChatBroadcast: true)
        : [];

    // Generate random messages for the generated participants
    final messages = useSeed
        ? generateRandomMessages(participants, memberName, '', hostName,
            forChatBroadcast: true)
        : [];

    // Assign the generated participants and messages to seedData
    final seedData = {
      'participants': participants,
      'messages': messages,
      'member': memberName,
      'host': hostName,
    };

    // Whether to use local UI mode; prevents making requests to the Mediasfu servers during UI development
    final useLocalUIMode = useSeed;

    return MaterialApp(
      title: 'Mediasfu Broadcast',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MediasfuBroadcast(
        // Configure the PrejoinPage widget with credentials and parameters
        PrejoinPage: ({
          required Map<String, dynamic> credentials,
          required Map<String, dynamic> parameters,
        }) {
          return PreJoinPage(credentials: credentials, parameters: parameters);
        },
        useLocalUIMode: useLocalUIMode,
        useSeed: useSeed,
        seedData: useSeed ? seedData : {}, // Pass seed data if useSeed is true
        credentials: credentials, // Pass global credentials
      ),
    );
  }
}

Example for Generic View

import 'package:mediasfu_sdk/mediasfu_sdk.dart'

void main() {
  runApp(const MyApp());
}

// Global credentials used for authentication
final credentials = {
  'apiUserName': "your_api_user_name",
  'apiKey': "your_api_key",
};

/// The main application widget responsible for setting up the UI and navigation.
///
/// Users have the option to provide a custom view by passing the [PreJoinPage]
/// widget, which can be tailored to their specific requirements. This flexibility
/// allows users to design and customize the prejoin experience according to their
/// needs, such as collecting additional information or providing specialized instructions.
/// When using the prejoin page, ensure to pass appropriate [credentials] for authentication.

    );
  }
}

In the provided examples, users can set useLocalUIMode to true during UI development to prevent unwanted connections to MediaSFU servers. Additionally, they can generate seed data for rendering UI components locally by using random data generators provided by the package.

Local UI Development in MediaSFU

During local UI development, the MediaSFU view is designed to be responsive to changes in screen size and orientation, adapting its layout accordingly. However, since UI changes are typically linked to communication with servers, developing the UI locally might result in less responsiveness due to the lack of real-time data updates. To mitigate this, users can force trigger changes in the UI by rotating the device, resizing the window, or simulating server responses by clicking on buttons within the page.

While developing locally, users may encounter occasional error warnings as the UI attempts to communicate with the server. These warnings can be safely ignored, as they are simply indicative of unsuccessful server requests in the local development environment.

Room Socket Events

In the context of a room's real-time communication, various events occur, such as user actions, room management updates, media controls, and meeting status changes. To effectively handle these events and synchronize the application's state with the server, specific functions are provided. These functions act as listeners for socket events, allowing the application to react accordingly.

Provided Socket Event Handling Functions:

Function	Explanation
userWaiting	Triggered when a user is waiting.
personJoined	Triggered when a person joins the room.
allWaitingRoomMembers	Triggered when information about all waiting room members is received.
roomRecordParams	Triggered when room recording parameters are received.
banParticipant	Triggered when a participant is banned.
updatedCoHost	Triggered when the co-host information is updated.
participantRequested	Triggered when a participant requests access.
screenProducerId	Triggered when the screen producer ID is received.
updateMediaSettings	Triggered when media settings are updated.
producerMediaPaused	Triggered when producer media is paused.
producerMediaResumed	Triggered when producer media is resumed.
producerMediaClosed	Triggered when producer media is closed.
controlMediaHost	Triggered when media control is hosted.
meetingEnded	Triggered when the meeting ends.
disconnectUserSelf	Triggered when a user disconnects.
receiveMessage	Triggered when a message is received.
meetingTimeRemaining	Triggered when meeting time remaining is received.
meetingStillThere	Triggered when the meeting is still active.
startRecords	Triggered when recording starts.
reInitiateRecording	Triggered when recording needs to be re-initiated.
getDomains	Triggered when domains are received.
updateConsumingDomains	Triggered when consuming domains are updated.
RecordingNotice	Triggered when a recording notice is received.
timeLeftRecording	Triggered when time left for recording is received.
stoppedRecording	Triggered when recording stops.
hostRequestResponse	Triggered when the host request response is received.
allMembers	Triggered when information about all members is received.
allMembersRest	Triggered when information about all members is received (rest of the members).
disconnect	Triggered when a disconnect event occurs.

Sample Usage:

// Example usage of provided socket event handling functions
import 'package:mediasfu_sdk/mediasfu_sdk.dart'show participantRequested, screenProducerId;

socket.value!.on('participantRequested', (data) async {
 
    // Handle 'participantRequested' event
    participantRequested(
      userRequest: data['userRequest'],
      parameters: {...getAllParams(), ...mediaSFUFunctions()},
    );
});

socket.value!.on('screenProducerId', (data) async {
  // Handle 'screenProducerId' event

    screenProducerId(
      producerId: data['producerId'],
      parameters: {...getAllParams(), ...mediaSFUFunctions()},
    );
});

These functions enable seamless interaction with the server and ensure that the application stays synchronized with the real-time events occurring within the room.

API Reference

For detailed information on the API methods and usage, please refer to the MediaSFU API Documentation.

If you need further assistance or have any questions, feel free to ask!

Troubleshooting

1. Interactive Testing with MediaSFU's Frontend: Users can interactively join MediaSFU's frontend in the same room to analyze if various events or media transmissions are happening as expected. For example, adding a user there to check changes made by the host and vice versa.

2. Reducing Terminal Log Clutter: When running your Flutter application on a physical device in debug mode, you might encounter excessive logs from Java that clutter the terminal output. To address this issue, you can use the following command to filter out irrelevant logs:

   flutter run | sed '/^.\// { /^\(V\|I\|W\|E\)\/flutter/!d }'
   

   This command will only display logs related to Flutter, excluding unnecessary logs from other sources. It helps in maintaining a cleaner terminal output for better debugging experience.

These troubleshooting steps should help users address common issues and optimize their experience with MediaSFU. If the issues persist or additional assistance is needed, users can refer to the documentation or reach out to the support team for further assistance.
