Android: The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher / IOS: Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)

[IbrahimHasan93]

In my flutter app am using pusher_client and when i upgraded kotlin version of the whole project i got this:
The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher.
The following dependencies do not satisfy the required version:
project ':pusher_client' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

my settings.gradle file looks like this:
pluginManagement {
def flutterSdkPath = {
def properties = new Properties()
file("local.properties").withInputStream { properties.load(it) }
def flutterSdkPath = properties.getProperty("flutter.sdk")
assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
return flutterSdkPath
}
settings.ext.flutterSdkPath = flutterSdkPath()

includeBuild("${settings.ext.flutterSdkPath}/packages/flutter_tools/gradle")

repositories {
    google()
    mavenCentral()
    gradlePluginPortal()
}

}

plugins {
id "dev.flutter.flutter-plugin-loader" version "1.0.0"
id "com.android.application" version "7.3.0" apply false
id "org.jetbrains.kotlin.android" version "1.9.20" apply false
id 'com.google.gms.google-services' version '4.4.2' apply false
}

include ":app"

in pubspec.yaml:
environment:
sdk: '>=3.2.6 <4.0.0'

in android/app/build.gradle:
compileSdkVersion 34
minSdkVersion 28
targetSdkVersion 34
signingConfig signingConfigs.debug
and in the dependencies:
dependencies {
implementation 'com.android.support:multidex:2.0.1'
implementation platform('com.google.firebase:firebase-bom:32.1.1')
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.1.5'
implementation 'androidx.window:window:1.0.0'
implementation 'androidx.window:window-java:1.0.0'
}

as For IOS :
Error (Xcode): Building for 'iOS-simulator', but linking in object file (/../Documents/flutterApps/app/ios/Pods/Sodium/Sodium/libsodium/libsodium-ios.a[arm64]3) built for 'iOS'

Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)

Could not build the application for the simulator.
Error launching application on iPhone 11 pro max.

Can anyone help please?

@IbrahimHasan93, I am facing the same issue. Have you managed to solve it yet? @chinloyal, please solve the problem as soon as possible. My project depends on this plugin.

@IbrahimHasan93 Intead of using pusher_client use pusher_channel_flutter package. That will solve the problem.
