Description

Load ListWidget and run the app.
Increment first list item by clicking it 3 times. Scroll to bottom and then scroll to top, the count will get reset

Functional/Product Requirement

There should be 100 list items, each should be set at 0 initially and user can increment its count.
The count incremented by user should be persisted when he scrolls the list.

Solve the functional requirement.
Review this file from Code Review perspective, list the issues and what changes should be made, perform the changes to the file.
Think of it as a intern checked in this code and as a senior has to code review and fix the code from implementation perspective to make it correct and efficient.
Send the fixed file back to the recruiter.

Proposed Solution with State Management
We will be using a State Management framework to maintain the state of the list.
There are many libraries available like Provider, Bloc, Riverpod, GetX, etc that provide state management solutions.
All libraries in the underlying framework work the same. They consumes events and emit new states.
We will be using Bloc for this Product Requirement.
Bloc State management emits only the changes that occur in the list. This will help in dispatching selective updates if the state becomes complex in the future.
The BLoC pattern reduces tight coupling between widgets. The ListItemWidget doesn't need to know about the parent ListWidget, it interacts with the state through the ItemCubit. Thus Separation of Concerns is achieved.

Convert ListItemWidget from Stateful to Stateless Widget. This removes unnecessary rebuilds of the Item widget.
Added the Equatable package to enable list equality for the Item class.
Added conditional logic to BlocBuilder's buildWhen callback. The BlocBuilder widget will only rebuild if the condition in buildWhen callback.
We have enforced, that Builder should only build if
