    setWindowTitle('Title');
    // setWindowMinSize(const Size(20, 20));

To change the default Icon for a flutter desktop application, you have to replace

• For Windows windows/runner/resources/app_icon.ico
• For MacOS macos/Runner/Assets.xcassets/AppIcon.appiconset/app_icon_*.png

Note that there are tools that can generate the iconset for macos, for example this online tool.
