Error when I'm trying to build an android app using flutter

The error is the following:

e: /Users/Houssame/.gradle/aches/transforms-3/e5c5aa35234c44d5264fd87af440dbf9/transformed/fragment-1.7.1-api.jar!/META-INF/fragment_release.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.

[!] Your project requires a newer version of the Kotlin Gradle plugin.
Find the latest version on https://kotlinlang.org/docs/releases.html#release-details, then update the │ version number of the plugin with id "org.jetbrains.kotlin.android" in the plugins block of
/Users/Houssame/Desktop/demo 3/android/settings.gradle.
Alternatively (if your project was created before Flutter 3.19), update
/Users/Houssame/Desktop/demo 3/android/build.gradle
ext.kotlin_version = ''

I did upgrade all the version for Gradle but I have the same error, the app is ruining normally in emulator Android Studio.

Android/build.gradle

buildscript { ext.kotlin_version = '2.0.20' repositories { google() mavenCentral() }

allprojects { repositories { google() mavenCentral() } }

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

tasks.register("clean", Delete) { delete rootProject.buildDir }

Thank you!

Copy these as they are: edit your aplicationId and namespace to match your applicationId
