I searched everywhere and just can't understand if the new projects created in flutter (New Flutter Project using Android Studio) should already be using to Gradle 4.1, cause when I create a new project, it is still created using the old version.

From this post [https://github.com/flutter/flutter/wiki/Updating-Flutter-projects-to-Gradle-4.1-and-Android-Studio-Gradle-plugin-3.0.1] seems like it, right now, should already be created using the new version, got this conclusion by: "After #13492, Flutter tooling creates projects based on Gradle 4.1 and the Android Studio Gradle plugin version 3.0.1."

This confuses me even more, I updated everything and still creating projects in the old Gradle version.
