result_kit 0.2.0

Typed results and async state models for clean Dart and Flutter applications.

0.2.0

Breaking changes

• Renamed concrete class DataError<T> to DataFailure<T>. The DataState.failure() factory constructor is unchanged, but any code that pattern-matches directly on DataError (e.g. is DataError, case DataError()) must be updated to DataFailure.

New features

• Added PaginationMetadataX extension on PaginationMetadata with .skip, .limit, and .nextPage convenience getters.

• AsyncUseCase, AsyncUseCaseNoParams, SyncUseCase, SyncUseCaseNoParams interfaces.
