+
+A common platform interface for the [window_manager](https://pub.dev/packages/window_manager) plugin.
+
+## Usage
+
+To implement a new platform-specific implementation of window_manager, extend `WindowManagerPlatform` with an implementation that performs the platform-specific behavior, and when you register your plugin, set the default `WindowManagerPlatform` by calling `WindowManagerPlatform.instance = MyPlatformWindowManager()`.
