Error

#
# Fatal error in: ../../../../usr/local/google/home/sakal/code/webrtc-aar-release/src/sdk/android/src/jni/jni_generator_helper.cc, line 28
# last system error: 88
# Check failed: !clazz.is_null()
# org/webrtc/WebRtcClassLoader

Fix

• Add file android/app/proguard-rules.pro

## Flutter WebRTC
-keep class com.cloudwebrtc.webrtc.** { *; }
-keep class org.webrtc.** { *; }

• Update android/app/build.gradle

buildTypes {
    debug {
        debuggable true
        signingConfig signingConfigs.debug
    }
    release {
        debuggable false
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.release
    }
}
