asyncredux-optimistic-update-mixin

Optimistic updates in Flutter provide instant UI feedback by applying state changes locally before server confirmation. This mixin applies optimistic values immediately and automatically rolls back the state if the server communication fails.

State rollback in AsyncRedux is handled by overriding the required methods to determine the rollback state. If server communication fails, the mixin automatically reverts the state to its prior condition using these overridden rollback functions.

Rapid UI toggling without overwhelming the server is managed using the OptimisticSync mixin, which provides value coalescing. This ensures that frequent user interactions update the local state instantly while consolidating server requests efficiently.

Yes, the OptimisticSyncWithPush mixin handles real-time server push scenarios with AsyncRedux state management. It uses revision tracking to synchronize local state updates with incoming server pushes, ensuring data consistency across conflicts.

To apply optimistic values and perform server communication, you must override the applyValueToState() and sendCommandToServer() methods. These functions apply the local state changes instantly and manage the asynchronous server interaction respectively.

Use OptimisticCommand for one-time operations like creating, deleting, or submitting data where immediate UI feedback and failure rollback are needed. Use OptimisticSync for rapid toggling interactions that require value coalescing to manage server load.
