I'm not sure about the condition for maxWidth but it was not defined as strict requirement so hard to judge if that's the correct value.

final shouldButtonDisplay = constraints.maxWidth > 744;

Theoretically better approach would be to use ResponsiveBuilder instead of hardcoding the breakpoint (744) and manually using LayoutBuilder. Consider to improve it in the next PR.
