31.36 Flutter Desktop Size Windows


See Section 31.37 to set the window size of a desktop application through the window_manager package.

Alternatively we observe that the Flutter Windows native desktop application size is set in windows/runner/main.cpp. There we find the default desktop window size which is set to be 1280 by 720 at line 29 in my current version.

29  Win32Window::Size size(1280, 720);

To reduce the default window width and height on startup to have dimensions more like a mobile app, we can change the settings here:

perl -pi.bak -e 's|1280, 720|450, 700|' windows/runner/main.cpp

The appropriate line in the file will be updated:

29  Win32Window::Size size(450, 700);
