State Management (BLoC Default)

When to use

• BLoC: default for feature flows, async orchestration, and business-facing UI state.
• Cubit: small UI-only state (toggles, selected tab) where events/transformers are unnecessary.
• Provider: a lightweight UI controller (e.g., filters) when it stays UI-scoped and does not contain business logic.

Steps

1) Choose the right tool

Quick rule:

• If it coordinates async work and talks to repositories: BLoC.
• If it only holds ephemeral UI state: Cubit.
• If it’s a tiny widget-scoped controller and BLoC would be noise: Provider.
