Plugin [id: 'com.android.application'] not found in Flutter project with build.gradle.kts (Even After Changing Versions and Settings)

Question

Hello everyone,

I’m facing an issue with my Flutter project, which uses Gradle with Kotlin DSL (build.gradle.kts). When I try to build the project, I keep getting the following error:

Plugin [id: 'com.android.application'] was not found in any of the following sources:

What I’ve tried so far:

• Plugin configuration:
  I added the plugins both in settings.gradle.kts and directly in build.gradle.kts, but the error persists.

plugins {
    id("com.android.application")
    id("kotlin-android")
    id("dev.flutter.flutter-gradle-plugin")
}

• Gradle version changes:
  I tested with multiple Gradle versions, including:

• 8.2.0

• 8.1.0
  Even after switching versions and syncing the project, the issue remains.

• Server connection:
  Flutter connects to a Chinese server to download packages, but it doesn’t stop me from downloading dependencies, so I don’t think the server itself is the issue.

System setup:

• Flutter: 3.29.0
• Gradle: 8.2.0 (also tested on 8.1.0)
• Kotlin: 1.9.20
• Android SDK: 35.0.1

Question:

Has anyone worked with Flutter projects using Kotlin DSL for Gradle?
Is there something I might be missing or misconfiguring?
I’d really appreciate any insights or suggestions!
