You need to upgrade Kotlin to version 1.5.1 but for the Flutter 2.9.1 best version is 1.5.31. Look here.

    buildscript {
-    ext.kotlin_version = '1.1.15'
+    ext.kotlin_version = '1.5.1'

you have 2 ways to solved this problem, first:

Clicking on Gradle (on the right side bar) ->
Then under :app
Then choose assembleDebug (or assembleYourFlavor if you use flavors)

or its because of your network: network blocked non secured http download request. I changed my network and the gradle build completed itself.

https://docs.flutter.dev/release/breaking-changes/kotlin-version According to this you need to update kotlin version to 1.5.31 inside <app-src>/android/build.gradle
