Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.10 and higher

Question

I am facing a strange error in my project. I tried solutions to similar questions but they did not work. I and my coworker tried to update the barcodescan but nothing changed.

Here is the error message.

Launching lib/main.dart on Android SDK built for x86 in debug mode... Running Gradle task 'assembleDebug'...

**FAILURE: Build failed with an exception.

* What went wrong:
The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.10 and higher.
The following dependencies do not satisfy the required version:
project ':barcode_scan' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.51

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUİLD FAILED in 978ms
Exception: Gradle task assembleDebug failed with exit code 1

This is my android/build.gradle file

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        //classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.51"
    }
}
allprojects {
    repositories {
        google()
        jcenter()
    }
}
rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

And finally my pubspec.yaml file
