The project assigned to me is a huge project with multiple screens and widgets. This project does not follow any kind of architecture. We are facing many issues related to state management and decided to move the project to bloc. Now my question is what could be the best approach to move this existing project, can we do it in module wise or do we need to start from scratch. Is there any guideline exist to shift existing projects to bloc. I understand it completely depends on the project and requirements but still, any help would be greatly appreciated.
