Installation

First, add flutter_zoom_plugin as a dependency in your pubspec.yaml file.

Use the git tags for deployments as milestones as the master branch is considered active development.

  flutter_zoom_plugin:
      git:
        url: git://github.com/decodedhealth/flutter_zoom_plugin.git
        ref: 0.0.8

Please use master for Apple app store build deployments.

  flutter_zoom_plugin:
      git:
        url: git://github.com/decodedhealth/flutter_zoom_plugin.git
        ref: master

iOS

Add two rows to the ios/Runner/Info.plist:

• one with the key Privacy - Camera Usage Description and a usage description.
• and one with the key Privacy - Microphone Usage Description and a usage description.

Or in text format add the key:

<key>NSCameraUsageDescription</key>
<string>Need to use the camera for call</string>
<key>NSMicrophoneUsageDescription</key>
<string>Need to use the microphone for call</string>

NOTE for testing on the iOS simulator

If you want to use the iOS Simulator to test your app, you will need to ensure you have the iOS Dev Zoom SDK as a dependency.

To use the Dev Zoom SDK, run the following

flutter pub run flutter_zoom_plugin:unzip_zoom_sdk dev

To switch back to the normal Zoom SDK, simply run

flutter pub run flutter_zoom_plugin:unzip_zoom_sdk

Android

Change the minimum Android sdk version to at the minimum 21 in your android/app/build.gradle file.

minSdkVersion 21

Add the zoom proguard content to your android project: https://github.com/zoom/zoom-sdk-android/blob/master/proguard.cfg

Start a Meeting - Non-login user

You need to obtain the User Token and Zoom Access Token (ZAK) in order to start meetings for a user. They are unique authentication tokens required to host a meeting on behalf of another user.

Example of getting User Token and ZAK here

More info about the User Token and Zoom Access Token here.

In order to run the example app:

1. Create an JWT app to get a JWT token using the instructions here.

2. Create a meeting (with a host of course) then get the Meeting ID (can be a 10 or 11-digit number).

3. Use the Zoom API to obtain the tokens from the host.

   # User token
   curl --location --request GET 'https://api.zoom.us/v2/users/<zoom_user_id>/token?type=token&access_token=<jwt_token>'
      
   # Access token
   curl --location --request GET 'https://api.zoom.us/v2/users/<zoom_user_id>/token?type=zak&access_token=<jwt_token>'
   

   Note for obtaining tokens:

   The user must log in using their email and password to get the user token. If a user signed into Zoom using Google or Facebook, a null value will be returned for the token.

4. Pass the meeting ID and tokens to the plugin.
