Gradle error on new Flutter app using emulator and phone

Hello I haven't used Flutter and Dart in a long time and when i tried to make a new app and run it in emulator this error popped up:
FAILURE: Build failed with an exception.

Some other errors popped up as well but when I added the sdkverison in gradle it resolved some issues but this one stayed. Here is my gradel file:
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 GradleException("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'

The rest of the app is basic flutter app when you first run command flutter create appName. So if you could give me a solution to this problem it would be great so I can revise and learn new things in flutter. Thanks in advance :)

I m not sure.
But in my app build.gradle "compileSdkVersion 30" looks like this without "()", May be problem with this

please, kind people

Try to flutter clean first it seems the machine cannot find your flutter.sdk
Have you put the file from firebase google-services.json to the folder android/app folder?
And also add the depedencies for firebase ? on file build.grandle but not inside android/app folder

repositories {
google()
jcenter()
}

Open the android/build.gradle file, and check the version of com.android.tools.build:gradle :
buildscript {
...
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
...
}
}
Make that version smaller, until some version works.
The version can be choosed from here, in the plugin column:
https://developer.android.com/studio/releases/gradle-plugin#updating-gradle
The problem occurs when gradle is too old and android gradle plugin is too new.

Try these steps. Open the Gradle Scripts/gradle-wrapper.properties file.
Replace the existing version with '6.7-all.zip':
distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip
Then in the build.gradle file, first replace the version in classpath to 4.1.0, then replace 'jcenter()' with 'mavenCentral()':
buildscript {
...
repositories {
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'
...
}
}
allprojects {
repositories {
google()
mavenCentral()
}
}

Goto event_notifier\android\build.gradle ...
These dependencies should make it build:

jdk7:$kotlin_version"
compile "com.google.firebase:firebase-analytics:17.2.2"
compile "com.android.support:multidex:1.0.1"
}
The actual problem seems to be a quite outdated version of the Android Gradle Plugin.
You'd have to upgrade to something more current to use implementation:
classpath "com.android.tools.build:gradle:4.0.1"
And maybe already start with current androidx packages ...because else you'll be stuck at the latest version of Firebase libraries, which use these obsolete support libraries. That Flutter project may generally be outdated and might require some refactoring (unless using the above compile):
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:1.3.72"
implementation "com.google.firebase:firebase-analytics:17.4.4"
// https://mvnrepository.com/artifact/androidx.multidex/multidex
implementation "androidx.multidex:multidex:2.0.1"
}

Adding Firebase to flutter project, breaks the project

I followed several tutorials to add firebase to my flutter project. But no matter what I do, my project breaks with the same exact failure.
I tried creating new projects, and got the same exact failure.
For now, I followed this tutorial.
Right after changing the app level build.gradle file, I start to build my app. I use flutter run to run the app on my physical device.
Every single time, I get hit by the same exact error, and scouring on the internet, didn't solve the issue, hence the question.
My Error:
* Error running Gradle:

It's due to AndroidX compatibility,
Create a new project and follow the steps below:
In order for your project to be AndroidX compatible, you need to add the following two lines to your gradle.properties file:
android.useAndroidX = true
android.enableJetifier = true
Make sure in your app build.gradle file that the compileSdkVersion and targetSdkVersion are both set to 28
Remove all the lines with the comment "Remove" from your main app build.gradle file:
android {
compileSdkVersion 28
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
applicationId "YOUR_APPLICATION_ID"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" //Remove
}
buildTypes {
release {
signingConfig signingConfigs.debug
}
}
}
dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2' // Remove
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' // Remove
}
If you try to build the project you will get an error that has something to do with the core library for AndroidX, To fix it, add the code in the subprojects category in your project level build.gradle file:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
}
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'androidx.core'
&& !details.requested.name.contains('androidx') ) {
details.useVersion "1.0.1"
}
}
}
}
}
NOTE 1: In the 4th step rememeber that the subprojects category should be bellow the dependecies category, if not present then copy and paste the code given.
I would prefer to try the above steps in Android Studio, Save all the files and restart the project, Add the Firebase dependencies and whatever the changes are told to do in the documentation: Documentation. It would work.
BEST OF LUCK!!
