My project requires a newer version of the Kotlin Gradle plugin, but the suggested fix doesn't work

Question

so I just upgraded flutter and quickly got this error:

┌─ Flutter Fix ────────────────────────────────────────────────────────────────────────────────┐
│ [!] Your project requires a newer version of the Kotlin Gradle plugin.                       │

└──────────────────────────────────────────────────────────────────────────────────────────────┘
Exception: Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

This is a known breaking change when upgrading.

I applied the suggested fix but the error doesn't go away

Here is my \android\build.gradle:

buildscript {
    ext.kotlin_version = '1.6.10' //there was nothing here before
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath 'com.google.gms:google-services:4.3.5'
    }
}

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

Things I tried:

-flutter clean

-Restart VS Code

-Turn off and cold boot emulator again.

-Looking at similar threads

-Adding implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.6.10" to my app/build.gradle

-Open /android in Android Studio and trying to Gradle Sync (Gradle sync failed: Sync failed: reason unknown (1 m 26 s 622 ms))

Solution 1

try this

 dependencies {
        classpath 'com.android.tools.build:gradle:7.0.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.10'
    
    }

and go android>gradle>wrapper>gradle-wrapper.properties file change zip file version

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-all.zip

Solution 2

change the kotlin version in build.gradle from XXX to 1.6.10 or to newer version

build.gradle>gradle>android
