Configuration

IOS

• Note: Example compilable with XCode 12.2 & Flutter 1.22.4.

Podfile

Ensure in your Podfile you have an entry like below declaring platform of 11.0 or above and disable BITCODE.

platform :ios, '12.1'

...

post_install do |installer|
  installer.pods_project.targets.each do |target|
  flutter_additional_ios_build_settings(target)
      target.build_configurations.each do |config|
        config.build_settings['ENABLE_BITCODE'] = 'NO'
        config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
         end
     end
   end

Info.plist

Add NSCameraUsageDescription and NSMicrophoneUsageDescription to your Info.plist.

<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) MyApp needs access to your camera for meetings.</string>
<key>NSMicrophoneUsageDescription</key>
<string>$(PRODUCT_NAME) MyApp needs access to your microphone for meetings.</string>

Android

Gradle

Set dependencies of build tools gradle to minimum 3.6.3:

dependencies {
    classpath 'com.android.tools.build:gradle:3.6.3' <!-- Upgrade this -->
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

Set distribution gradle wrapper to minimum 5.6.4.

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip <!-- Upgrade this -->

AndroidManifest.xml

Meet Hour's SDK AndroidManifest.xml will conflict with your project, namely the application:label field. To counter that, go into android/app/src/main/AndroidManifest.xml and add the tools library and tools:replace="android:label" to the application tag.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="yourpackage.com"
    xmlns:tools="http://schemas.android.com/tools"> <!-- Add this -->
    <application 
        tools:replace="android:label"  
        android:name="your.application.name"
        android:label="My Application"
        android:icon="@mipmap/ic_launcher">
        ...
    </application>
...
</manifest>

Minimum SDK Version 23

Update your minimum sdk version to 23 in android/app/build.gradle

defaultConfig {
    applicationId "go.meethour.io.flutter.sdk_example"
    minSdkVersion 23 //Required for MeetHour
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

Proguard

MeetHour's SDK enables proguard, but without a proguard-rules.pro file, your release apk build will be missing the Flutter Wrapper as well as react-native code. In your Flutter project's android/app/build.gradle file, add proguard support

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.debug
        
        // Add below 3 lines for proguard
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

Then add a file in the same directory called proguard-rules.pro. See the example app's proguard-rules.pro file to know what to paste in.

Note
If you do not create the proguard-rules.pro file, then your app will crash when you try to join a meeting or the meeting screen tries to open but closes immediately. You will see one of the below errors in logcat.

## App crashes ##

Per Meeting Events

To listen to meeting events per meeting, pass in a MeetHourMeetingListener in joinMeeting. The listener will automatically be removed when an
onConferenceTerminated event is fired.

await MeetHour.joinMeeting(options,
  listener: MeetHourMeetingListener(onConferenceWillJoin: ({message}) {
    debugPrint("${options.room} will join with message: $message");
  }, onConferenceJoined: ({message}) {
    debugPrint("${options.room} joined with message: $message");
  }, onConferenceTerminated: ({message}) {
    debugPrint("${options.room} terminated with message: $message");
  }, onPictureInPictureWillEnter: ({message}) {
	debugPrint("${options.room} entered PIP mode with message: $message");
  }, onPictureInPictureTerminated: ({message}) {
	debugPrint("${options.room} exited PIP mode with message: $message");
  }));

Global Meeting Events

To listen to global meeting events, simply add a MeetHourListener with
MeetHour.addListener(myListener). You can remove listeners using
MeetHour.removeListener(listener) or MeetHour.removeAllListeners().

@override
void initState() {
  super.initState();
  MeetHour.addListener(MeetHourMeetingListener(
    onConferenceWillJoin: _onConferenceWillJoin,
    onConferenceJoined: _onConferenceJoined,
    onConferenceTerminated: _onConferenceTerminated,
    onPictureInPictureWillEnter: _onPictureInPictureWillEnter,
    onPictureInPictureTerminated: _onPictureInPictureTerminated,
    onError: _onError));
}

@override
void dispose() {
  super.dispose();
  MeetHour.removeAllListeners();
}

_onConferenceWillJoin({message}) {
  debugPrint("_onConferenceWillJoin broadcasted");
}

_onConferenceJoined({message}) {
  debugPrint("_onConferenceJoined broadcasted");
}

_onConferenceTerminated({message}) {
  debugPrint("_onConferenceTerminated broadcasted");
}

_onPictureInPictureWillEnter({message}) {
debugPrint("_onPictureInPictureWillEnter broadcasted with message: $message");
}

_onPictureInPictureTerminated({message}) {
debugPrint("_onPictureInPictureTerminated broadcasted with message: $message");
}

_onError(error) {
  debugPrint("_onError broadcasted");
}
