screenshot_desktop #

A Dart package for taking desktop screenshots on macOS and Windows.

Unlike many other screenshot packages, this one does not depend on Flutter. It can be used in command-line tools or any other pure Dart environment, while remaining fully compatible with Flutter applications.

Features #

• Multi-monitor support: List all available monitors and their resolutions.
• Specific monitor capture: Take a high-resolution screenshot of a specific monitor.
• Window capture: List all available windows and capture screenshots of specific windows.
• Pure Dart: No Flutter dependency required.
