Getting Started

Installation

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, set up the Zoom SDK by following these steps:

  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.

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

  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:

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

Verify Signature:

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

Implementation Guide

Initializing the SDK

Initialize the Zoom SDK with your JWT token:

import 'package:flutter_zoom_meeting_wrapper/flutter_zoom_meeting_wrapper.dart';

bool isInitialized = await ZoomMeetingWrapper.initZoom(jwtToken);

Joining a Meeting

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

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

Troubleshooting Common Issues

  • JWT Token Invalid : Ensure your API Key and Secret are correct, and verify that your system time is accurate.
  • Failed to Initialize SDK : Check that you have a stable internet connection and are using a valid JWT token.
  • Cannot Join Meeting : Double-check that the meeting ID and password are correct.

Current Limitations

  • 🖥️ Screen sharing capabilities are limited to platform capabilities.
