Comando Run não abre emulador (problema em settings.gradle)

Boa tarde gente, tentei rodar o código main no emulador de Android Pixel_3a_API_30_x86 e aparece este erro:

FAILURE: Build failed with an exception.

* What went wrong:
Could not open settings generic class cache for settings file 'C:\Users\Fernando\bytebank\android\settings.gradle' (C:\Users\Fernando\.gradle\caches\6.7\scripts\1fnwrr8g4rohfp291nvlxj5qe).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 60

* 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

A seguir vai o código presente no arquivo settings.graddle, onde dá problema na linha 3 e 4, em File() e Properties() respectivamente (Cannot resolve symbol).

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"

Se alguém souber de algo, por favor diga, uma boa tarde!
