    repositories {

    jcenter()

    }

    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

flutter doctor:

    first i ran this command in console:

    flutter pub cache repair

    then deleted this line of code in android/app build.gradle

    classpath 'com.android.tools.build:gradle:8.1.2'

    and ran this command :

    flutter pub get

    eventually after afew hours of downloading, it fixed.

    i get this proble and solve it with this code added to app/build.gradle

    allprojects {
           .
           .
           .       
      } // keep all project and under it add this code
ext {
    compileSdkVersion   = 34
    targetSdkVersion    = 34
    appCompatVersion    = "1.7.0" }

    and under the :

    rootProject.buildDir = '../build'

    add this lines of code :

    subprojects {
    afterEvaluate {
        android {
            compileSdkVersion 34
        }
    }
}

    then run again

    flutter build apk
