Flutter Issue Troubleshooting on macOS

I'm experiencing a problem with my Flutter code and need assistance. The error message reads: "Cannot resolve symbol 'Properties'."

I’m working on a macOS and using Android Studio for Flutter development. I have installed all necessary Flutter and Dart plugins.

pluginManagement {
def flutterSdkPath = {
def properties = new Properties()
file("local.properties").withInputStream { properties.load(it) }
def flutterSdkPath = properties.getProperty("flutter.sdk")
assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
return flutterSdkPath
}()


Problem is:

Cannot resolve symbol 'Properties'

Key requirements for this project:
- Expertise in Flutter
- Proficient in Android Studio
- Strong problem-solving skills
- Familiarity with macOS
- Ability to explain technical issues in a comprehensible manner
