Installation

Creating a Project​

To get started with the StreamVideo Flutter SDK, open your terminal or IDE and create a new project:

flutter create video_demo

Next, in your project directory (video_demo), install the Stream Video SDK using the following:

flutter pub add stream_video_flutter

This will automatically install the latest version of the Stream SDK from pub to the dependencies section of your pubspec.yaml.

Permissions​

Making video calls requires the usage of the device's camera and microphone. Therefore, before you can make and answer calls, you need to request permission to use them within your application.

The following permissions must be granted for both Android and iOS:

  • Internet Connectivity
  • Camera
  • Microphone (+ control audio settings to adjust audio level & switch between speaker & earpiece)
  • Bluetooth (wireless headset)

iOS​

Xcode Permission configuration

For iOS, you need to add the following keys and values to your Info.plist file at a minimum:

Privacy - Camera Usage Description - "<Your_app_name> requires camera access to capture and transmit video"

Privacy - Microphone Usage Description - "<Your_app_name> requires microphone access to capture and transmit audio"

Android​

For Android, similar permissions are needed in <project root>/android/app/src/main/AndroidManifest.xml

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<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" />

With Android specifically, you will also need to add additional permission if you would like to use Bluetooth devices:

<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />
