🚨 Known Operational Defects

Errors hidden behind Keypad

There's a problem with Snackbar's Z-index. It shows always under BottomSheet by default. See Issue: #63254. Item purchase keypad interface is implemented in showModalBottomSheet so, any errors will be hidden behind the keypad.

Wrong Autocompletion Details?

Autocompletion takes "last created" item details and not necessarily the "last purchased". So, if a purchase's purchase date is manually modified, the autocompletion will use it the next time. Just re-enter the price, after that it will be fine again until purchase date is manually overridden.

Flutter M3?

In Flutter's Material3 implementation, surfaceTintColor overlay is meant to animate when elevation changes but, since default shape and borderRadius is null, the Material widget optimizes out this animation from the AppBar.

This animated elevation color change is meant to be aesthetically similar to a heavy Gaussian blur BG and not having a smooth transition defeats that purpose.

This can be solved by adding a shape:

MaterialApp(
  theme: ThemeData(
    appBarTheme: const AppBarTheme(
      shape: RoundedRectangleBorder(),
    ),
  ),
)

No more abrupt coloring on elevation changes.
