BUILD FAILED in 10s

I think I have some problems with my 'android\build.gradle'&'app\build.gradle'.
at android\build.gradle:

subprojects {
    project.evaluationDependsOn(':app')
}

I think some problems with this ':app'->cause my builder has problem with evaluating project ':app'.

and 'app\build.gradle':

android {

this line has problem. but i don't know how to solve it.
I will write all code of this file at bottom of the article.

I tried to...

delete all cash at Intellij & restart
add classpath at my 'android\build.gradle'

dependencies {
        classpath 'com.android.tools.build:gradle:3.5.4'
        classpath 'com.google.gms:google-services:4.3.13'
//        classpath 'com.android.tools.build:gradle:7.1.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.21"
    }

add jcenter()&mavenCentral() at my 'android\build.gradle'
remove some code at app build file

useProguard true

& add some code.

shrinkResources true

move my key.jks file to '..\android'directory.

I have some Qs

in key.properties file, I write my PW with ''. ex: storePassword='myPWHere' this form is right?
At Intellij, my proguard-rules.pro file looks like has some ERRORS like this I think this is just Intellij's mistake. It is true?
at Flutter project, android directory's moduel name has some form?

Here is my code

this is app\build.gradle:

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new FileNotFoundException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}


def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}


def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

//def flutterCompileSdkVersion = localProperties.getProperty('flutter.flutterCompileSdkVersion')
//if (flutterCompileSdkVersion == null) {
//    flutterCompileSdkVersion = '31'

Try This

put minSdkVersion 20+

in android/build.gradle

 dependencies {
      classpath 'com.android.tools.build:gradle:7.1.2'

in gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-all.zip

OR

in android/build.gradle

 dependencies {
      classpath 'com.android.tools.build:gradle:4.1.0'

in gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-7.0-bin.zip

Change build gradle latest version.

In android/build.gradle:

dependencies{
  classpath 'com.android.tools.build:gradle:7.3.1'

In gradle-wrapper.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-all.zip

If you have still the same error, try to remove properties from the release section in app/build.gradle, like minifyEnabled, shrinkResources.

buildTypes{
      release{
            minifyEnabled false
            shrinkResources false
            useProguard false
            debuggable false

hope so it will be helpful.
