Overview
The flutter_window_close package enables Flutter applications on desktop platforms to intercept window close events and prompt users for confirmation before exiting. This is particularly useful for apps that need to save unsaved data or prevent accidental closure. It provides a simple API to register a callback that runs when the user attempts to close the window, allowing developers to show custom dialogs or perform cleanup tasks. The package supports macOS, Windows, Linux, and Web, making it ideal for cross-platform desktop applications requiring graceful shutdown handling.
