Getting Started

Installation

To begin using the Flutter Zoom Meeting Wrapper in your project, add the following to your pubspec.yaml file:

dependencies:
  flutter_zoom_meeting_wrapper: ^0.0.1

Run flutter pub get to install the package.

Mandatory Zoom SDK Setup

For the plugin to function correctly, you need to set up the Zoom SDK:

1. Download the Zoom SDK ZIP from this link
2. Extract the ZIP file after downloading
3. Copy the libs folder and paste it inside your Flutter pub-cache directory at:

~/.pub-cache/hosted/pub.dev/flutter_zoom_meeting_wrapper-0.0.1/android/

Note: Replace 0.0.1 with the version you’re using, if different.

4. Alternatively, run the following command to open the folder directly:

open ~/.pub-cache/hosted/pub.dev/flutter_zoom_meeting_wrapper-0.0.1/android

⚠️ Important: The libs folder must be placed in the correct location for the plugin to function properly.

Setting Up Zoom API Credentials

To use the Zoom Meeting SDK in your application, you’ll need to:

1. Create a Zoom Developer Account at Zoom Marketplace
2. Create a new app in the Zoom Marketplace
3. Obtain your API Key and API Secret from the app credentials page
4. Use these credentials to generate your JWT token

Generating a JWT Token

You can generate a Zoom JWT token using jwt.io with the following payload and signature:

Payload:

json{
  "appKey": "ZOOM-CLIENT-KEY",
  "iat": ANY-TIME-STAMP, 
  "exp": ANY-TIME-STAMP, // greater than iat
  "tokenExp": ANY-TIME-STAMP // greater than iat
}

Verify Signature:

HMACSHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
  "ZOOM-CLIENT-SECRET"
)

Implementation Guide

Initializing the SDK

First, initialize the Zoom SDK with your JWT token:

import 'package:flutter_zoom_meeting_wrapper/flutter_zoom_meeting_wrapper.dart';

// Initialize Zoom SDK
bool isInitialized = await ZoomMeetingWrapper.initZoom(jwtToken);

Joining a Meeting

Once initialized, you can join a Zoom meeting with this simple code:

bool joinSuccess = await ZoomMeetingWrapper.joinMeeting(
  meetingId: "your_meeting_id",
  meetingPassword: "meeting_password",
  displayName: "Your Name",
);

When implementing the Flutter Zoom Meeting Wrapper, you might encounter these common issues:

• JWT Token Invalid: Ensure your API Key and Secret are correct, and verify that your system time is accurate.
