menuWidth property

double menuWidth
final

The width of the menu when it is full sized.

Values from 250...304 work well. The Drawer will be the same width as the menu, when the menu is shown in a Drawer.

Defaults to _kMenuWidth 275.

Standard Drawer in Flutter is 304 dp. If you make the menu wider than Flutter's default drawer size 304dp, the menu will be constrained to 304dp by Flutter SDK when used in the Drawer, it will however still shrink to the width provided here when smaller than 304dp.

The M3 design calls for the new Drawer to be even wider 360dp. https://m3.material.io/components/navigation-drawer/specs
