Can't find a solution for installing mapbox repo in flutter

[talghe]

The error I am getting is the following :

FAILURE: Build failed with an exception.

What went wrong: A problem occurred configuring root project 'android'.
Could not resolve all files for configuration ':classpath'. Could not find com.mapbox.mapboxsdk:mapbox-android-sdk:11.1.0. Searched in the following locations: - https://dl.google.com/dl/android/maven2/com/mapbox/mapboxsdk/mapbox-android-sdk/11.1.0/mapbox-android-sdk-11.1.0.pom - https://repo.maven.apache.org/maven2/com/mapbox/mapboxsdk/mapbox-android-sdk/11.1.0/mapbox-android-sdk-11.1.0.pom Required by: project :
Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. Get more help at https://help.gradle.org/.
BUILD FAILED in 2s Exception: Gradle task assembleDebug failed with exit code 1

This is the code I have in android/build.gradle :

buildscript {
ext {
agp_version = '8.6'
}
ext.kotlin_version = '1.8.0'
repositories {
google()
mavenCentral()
}

dependencies {
    classpath "com.android.tools.build:gradle:7.4.2"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.mapbox.mapboxsdk:mapbox-android-sdk:11.1.0'
}

}
allprojects {
repositories {
google()
mavenCentral()
jcenter()
maven {
url = uri("https://api.mapbox.com/downloads/v2/releases/maven")

        credentials.username = "mapbox"

        credentials.password = providers.gradleProperty("MY-SECRET-TOKEN").get()
        authentication { basic(BasicAuthentication) }
        }
}

}

And this is the code I have in android/app/build.gradle :

dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.multidex:multidex:2.0.1'
implementation 'com.jakewharton.timber:timber:5.0.1'
implementation 'com.mapbox.maps:android:11.1.0'
}

If someone could help me I would be very grateful!

I have tried to find a solution in stackoverflow and other places but none of these worked for me.
