I had an app that was working fine, but after updating to the latest version of flutter which is 2.8.1 it started showing errors regarding gradle files.
The error is:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:checkDebugAarMetadata'.

As you can see android studio can't find some files online, but actually when I follow the links provided in the error, I can download these files but as a .zip format not .aar
Now usually when I encounter such errors I simply download the files manually and place them in their respective folders, which we can get to from the error it self, for instance:
if we took a look at the first file that is core-1.6.0.aar we can see that the folder of it is androidx.core\core\1.6.0 and inside that folder android studio generates another folder with a random name like 7664385a7e39112b780baf8819ee880dcd3c4094, so the full path is like so:
C:\Users\%USERNAME%\.gradle\caches\modules-2\files-2.1\androidx.core\core\1.6.0\<here goes the folder with the random name>
But for the files mentioned above android studio didn't generate any folders, so I have no idea what to do with them, where should I put them? or is there any way to resolve the error and get rid of it?
My android\app\build.gradle 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'
}

Thanks in advance.
