31.42 Flutter MacOS Desktop Size

20230805

See Section 31.34 to set the window size of a desktop application through the window_manager package.

Alternatively we observe that the flutter MacOS native desktop application size is set in macos/Runner/Base.lproj/MainMenu.xib. There we find the default desktop window size which is set to be 800 by 770 by default.

            <rect key="contentRect" x="335" y="390" width="800" height="600"/>
...
                <rect key="frame" x="0.0" y="0.0" width="800" height="600"/>

To change 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|width="800" height="600"|width="450" height="700"|' macos/Runner/Base.lproj/MainMenu.xib

The appropriate line in the file will be updated:

            <rect key="contentRect" x="335" y="390" width="450" height="700"/>
...
                <rect key="frame" x="0.0" y="0.0" width="450" height="700"/>
