Goals:

• Showcase example use-case of each widget from flutter_list_bloc.
• Write in-code documentation with the use case of the widget.
• Example code must be plain and simple, remember to keep the structure flat and no nesting file structure.
• It is just an example app so write minimal code to showcase the usage. No need for 3rd party packages/plugins.
• Use DRY principle wherever applicable.
