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 Your project requires a newer version of the Kotlin Gradle plugin.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

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))
