Flutter gradle and build fails with "Unresolved reference: filePermissions" and other Kotlin errors in FlutterPlugin.kt

Question

I’m currently facing a strange error when trying to build my Flutter app on macOS.
I’m using Flutter 2.10.5 (via FVM) because my project SDK constraint is:

environment:
 sdk: ">=2.12.0 <3.0.0"

Whenever I try to run the app (fvm flutter run), I get this error:

Launching lib/main.dart on Redmi Note 5 in debug mode...
e: file:///Users/babanla/development/flutter/packages/flutter_tools/gradle/src/main/kotlin/FlutterPlugin.kt:764:21 Unresolved reference: filePermissions

✅ What I’ve tried

• Deleted Gradle caches and build folders:

  rm -rf android/.gradle
  rm -rf android/build
  fvm flutter clean
  fvm flutter pub get
  

• Verified Flutter version:

  Flutter 2.10.5 • Dart 2.16.2
  

• Updated Gradle versions in android/build.gradle and gradle-wrapper.properties:

  // build.gradle
  classpath 'com.android.tools.build:gradle:4.1.0'
  

  # gradle-wrapper.properties
  distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip
  

• Reinstalled Flutter SDK with FVM (fvm remove 2.10.5 → fvm install 2.10.5).

Still, the error persists and appears to originate from Flutter’s internal Gradle Kotlin files.

💻 My environment

• macOS (Sonoma 14.x)

• Flutter 2.10.5 (via FVM)

• Gradle 6.7

• Android Gradle Plugin 4.1.0

• Kotlin plugin (bundled with Flutter)

❓ My question

What could be causing these "Unresolved reference" errors in Flutter’s internal FlutterPlugin.kt file, and how can I properly reset or align my SDK and Gradle setup so that the project builds successfully again?
