Gradle can't find repositories to compile in flutter

I am developing an app in flutter 2.8.1 with firebase as backend. I have already advanced the project, and everything was going perfectly, but when I try to install the flutterfire_ui plugin the compiler gives the following error in the console.

 FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.

However none of the other firebase plugins give any problems, I can even access the links from the browser and download the files

build.gradle in android\app

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'
}

These are the dependencies in pubspec.yaml
