Flutter: Gradle task assembleDebug failed with exit code 1, using flutter without android studio

I am using Windows 11 machine and learning flutter for the first time and I am using it without Android Studio. I have installed and setup the android SDK manually. Added the SDK to path. Made an ANDROID_SDK_ROOT environment variable. Using the sdkmanager I have installed the "build-tools;33.0.1" "platforms;android-33" "platform-tools". I have added flutter sdk, platform-tools to path.

I have manually installed Gradle version 8.0.2 and added it to path as well.

Now I opened VS Code, opened the command palette and selected Flutter:New Project and then selecting Application.

I ran "flutter run" in the bash terminal but received the following error:
this is the error I get

Here is my gradle version:
gradle version 8.0.2

Flutter Doctor output:
I am using flutter without android studio

I have installed jdk version 19.0.2 and added that to path as well. Added JAVA_HOME variable in the environment.

I have tried changing the version of gradle in the gradle-wrapper.properties file:
Before the version was gradle-7.5-all.zip, so I simply changed it to gradle-8.0.2-all.zip, matching the one installed on my machine

Before the version was gradle-7.5-all.zip, so I simply changed it to gradle-8.0.2-all.zip, matching the one installed on my machine.
Due to this in my .gradle folder there are two subfolders made, which are 7.5 and 8.0.2.

I have tried deleting this folder and recompiling it, but it still doesn’t work.

I have searched the web and tried multiple solutions. I ran flutter clean, flutter pub get etc. etc. but none of them seem to work. What can I try next?

Here is my root/android/app/build.gradle script:

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'
}

apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

            // Signing with the debug keys for now, so `flutter run --release` works.

    }
}

flutter {

I tried many solutions available on the internet, but none of them seem to work.
