ChangeNotifierProvider vs ChangeNotifierProvider.value

Question

I am quite new to this framework and working on state management using provider package where I come across ChangeNotifierProvider and ChangeNotifierProvi

Answer 1

Does the official documentation help?

DO use ChangeNotifierProvider.value to provider an existing ChangeNotifier:

ChangeNotifierProvider.value(
  value: variable,
  child: ...
)

DON'T reuse an existing ChangeNotifier using the default constructor.

ChangeNotifierProvider(
  builder: (_) => variable,   
  child: ... 
)
