Yes, Flutter is a good choice for desktop app development. This cross-platform framework has become a popular choice among developers for creating high-performance and natively-looking Flutter desktop Apps. It enables you to scale your existing mobile project to the web and desktop: As a result of the Flutter desktop support, your mobile app can be ported to Windows, macOS, and Linux from a single code. You can get native-compiled performance without large browser engine dependencies, reach more users across the Windows, Mac App, and Linux Snap stores, and get full access to the underlying Win32, Cocoa, or UNIX platform APIs.
