Describe the bug
Calling flet build macos results in the following error
flet build macos
( ● ) Initializing macos build...
[19:13:25] Running build hooks...Running build hooks...
Because window_manager 0.5.1 requires the Flutter SDK and no versions of window_manager match >0.5.1 <0.6.0,
window_manager ^0.5.1 is forbidden.
So, because tt depends on window_manager ^0.5.1, version solving failed.
Flutter users should use `flutter pub` instead of `dart pub`.
