    try this: open Android Studio and go to SDK Manager, switch to the SDK Tools tab and check Android SDK Command-line Tools (latest) after the installation, run flutter doctor again.

    https://docs.flutter.dev/development/packages-and-plugins/using-packages

    open your project in visual studio code

from a visual studio code terminal run flutter pub upgrade (advances packages to the current version)
or run flutter pub add (first time usage)

Flutter saves the concrete package version found in the pubspec.lock lockfile.
