Overview
flutter_windowmanager_plus is a Flutter plugin that enables manipulation of Android WindowManager LayoutParams, allowing developers to control the position, size, and behavior of windows in Android applications. It provides access to system-level window properties, useful for creating floating widgets, overlays, or custom UI elements that persist across app boundaries.

It is specifically designed for Android and requires appropriate permissions and system settings to function properly.
