Bug: App blocks saving a food item even after all required information is completed

[LeticiaMonteiroo]

Bug description: The app blocks the user from saving a food item despite all the required fields being filled out correctly. This prevents users from adding new foods and disrupts the normal workflow.

Expected behavior: Once all required information (name, calories, macronutrients, quantity, etc.) is correctly filled, the app should allow saving the food item without errors.

Environment: Android

Possible solution: Fix the validation logic so that it accurately recognizes when all required fields are complete and allows saving.
