The key is to provide a UNIQUE INSTANCE of a bloc/cubit.
You SHOULDONT create MULTIPLE INSTANCES of the same bloc/cubit.
BlocProvider() CREATES & PROVIDES a NEW INSTANCE of a bloc/cubit.
BlocProvider.value() takes an ALREADY CREATED INSTANCE and then PROVIDES it further.
You can PROVIDE your cubit/bloc INSTANCES
- LOCALLY-when you want to provide the instance to A SINGLE SCREEN
- SPECIFICALLY-when you want to SPECIFICALLY PROVIDE the instance across one or more SCREENS
- GLOBALLY-when you want to provide the instance ACROSS ALL OF YOUR SCREENS
