I was able to get past this by adding the following at the top of my gradle.settings:

pluginManagement {
    buildscript {
        repositories {
            mavenCentral()
            maven {
                // r8 maven
                url = uri("https://storage.googleapis.com/r8-releases/raw")
            }
        }
        dependencies {
            // r8 version
            classpath("com.android.tools:r8:8.2.16-dev")
        }
    }
}

I also updated the android gradle plugin to 7.2.2 and the java compile options to use java 17.

According to the error message you posted, it sounds like the pluginManagement {} block must appear before any other statements in the script.

include ':app'

def localPropertiesFile = new File(rootProject.projectDir, "local.properties")
def properties = new Properties()

assert localPropertiesFile.exists()
localPropertiesFile.withReader("UTF-8") { reader -> properties.load(reader) }

def flutterSdkPath = properties.getProperty("flutter.sdk")
assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
apply from: "$flutterSdkPath/packages/flutter_tools/gradle/app_plugin_loader.gradle"

pluginManagement {
buildscript {
repositories {
mavenCentral()
maven {
// r8 maven
url = uri("https://storage.googleapis.com/r8-releases/raw")
}
}
dependencies {
// r8 version
classpath("com.android.tools:r8:8.2.16-dev")
}
}
}
