Any updates?

@praharshbhatt I am also facing same issue ? Did you fixed the issue ? If yes, please let me know how did you fixed.

@Mallikarjun7657 Can you retry with the following configuration:

  flutter_zoom_plugin:
    git:
      url: git://github.com/decodedhealth/flutter_zoom_plugin.git
      # Android
      #ref: 0.0.8
      # iOS
      ref: master

flutter clean
flutter pub cache repair
flutter run

Found a solution & it worked with Debug-RELEASE APK/Bundle

if you have a flutter project demo
then in android module of demo
--> Open build.gradle (app level) insert following code

   **Sample**
  implementation fileTree(include: '*.aar', dir: '<path to zoom-plugin-libs>') //path relative to  folder(aar files are stored) present in zoom-plugin dir

    **Example**
   implementation fileTree(include: '*.aar', dir: '../../flutter_zoom_plugin/android/libs/commonlib/')
   implementation fileTree(include: '*.aar', dir: '../../flutter_zoom_plugin/android/libs/mobilertc/')

--> Open gradle.properties insert following code

   android.enableDexingArtifactTransform=false

One last change is a suggestion to flutter-zoom-plugin, We changed a line in build.gradle of android module of this plugin :

   compileOnly files('libs/commonlib.aar') //path relative to libs folder present in zoom-plugin dir
   compileOnly files('libs/mobilertc.aar')    //path relative to libs folder present in zoom-plugin dir

Don't forget to add the proguard-rules for zoom libs/classes (if you skip it, it may not work in release APK/Bundle)

Preview for file proguard-rules.pro

  -keep class us.zoom.** { *; }
  -keep class us.zipow.** { *; }
  -keep class com.zipow.** { *; }
  -keep class org.webrtc.** { *; }
  -dontwarn us.zoom.**
  -dontwarn com.zipow.**

@amaurya08 Where i need to add these lines?
compileOnly files('libs/commonlib.aar') //path relative to libs folder present in zoom-plugin dir
compileOnly files('libs/mobilertc.aar') //path relative to libs folder present in zoom-plugin dir

Just for the sake of making my project work, I added the zoom plugin complete folder into project root folder. Here is the screenshot for the same and for the libs folder

I'm facing a similar issue, but Google states:

Note: You can't use the compileOnly configuration with AAR dependencies.

add compileOnly in plugin's android module project level (build.gradle) file. I am using follwoing gradle configuration

`group 'com.decodedhealth.flutter_zoom_plugin'
version '1.0-SNAPSHOT'

buildscript {
repositories {
google()
jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.4.0'
}

}

rootProject.allprojects {
repositories {
google()
jcenter()
}
}

apply plugin: 'com.android.library'

android {
compileSdkVersion 29

defaultConfig {
    minSdkVersion 21
    targetSdkVersion 29
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
}
lintOptions {
    disable 'InvalidPackage'
}

}

dependencies {
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
compileOnly files('libs/commonlib.aar')
compileOnly files('libs/mobilertc.aar')
}
`

Here is my flutter application's project level gradle
buildscript {
ext.kotlin_version = '1.3.50'
repositories {
google()
jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.4.3'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.3.3'
}

}

allprojects {
repositories {
google()
jcenter()
}
}

rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
delete rootProject.buildDir
}

App level gradle

flutter {
source '../..'
}

dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:multidex:1.0.3'
implementation fileTree(include: '*.aar', dir: '../../flutter_zoom_plugin-master/android/libs/')
}

_### And it's working 🗡️ _

[Nishakar561]

It is not working. I'm having the same issue.
Execution failed for task ':flutter_zoom_plugin:bundleDebugAar'.

Direct local .aar file dependencies are not supported when building an AAR. The resulting AAR would be broken because the classes and Android resources from any local .aar file dependencies would not be packaged in the resulting AAR. Previous versions of the Android Gradle Plugin produce broken AARs in this case too (despite not throwing this error).

[markfili]

any progress or solutions to this "direct local .aar file" problem?
