Because device_info_plus >=9.0.1 depends on
win32 >=4.0.0 <6.0.0 and pos_printer_manager
=0.0.5 depends on win32 ^2.3.1,
device_info_plus >=9.0.1 is incompatible with
pos_printer_manager >=0.0.5.
And because pos_printer_manager <0.0.5 doesn't
support null safety, device_info_plus >=9.0.1
is incompatible with pos_printer_manager.
So, because invu_supply depends on both
device_info_plus 9.1.0 and pos_printer_manager
any, version solving failed.
The current Dart SDK version is 3.1.4.
Because device_info_plus >=9.0.1 depends on win32 >=4.0.0 <6.0.0 and pos_printer_manager
The lower bound of "sdk: '>=2.7.0 <3.0.0'" mus
