BoxConstraints? constraints
final

Optional size constraints for the menu.

When unspecified, defaults to:

const BoxConstraints(
  minWidth: 2.0 * 56.0,
  maxWidth: 5.0 * 56.0,
)

The default constraints ensure that the menu width matches maximum width recommended by the Material Design guidelines. Specifying this parameter enables creation of menu wider than the default maximum width.
