SyncAdapter<M, D> class abstract

Base class for synchronization adapters for specific data sources.

This abstract class defines the interface for managing the synchronization of data between different sources. It is generic over:

• M: The type representing synchronization metadata.
• D: The type representing the detailed data associated with the metadata.

Implementers

• SerializableSyncAdapter
• SyncMetadataAdapter

Constructors

SyncAdapter({required String getMetadataId(M metadata), required FutureOr<bool> isCurrentMetadataBeforeOther(M current, M other)})

Constructs a SyncAdapter with the required functions for metadata handling.

Methods

fetchDetail(M metadata) → FutureOr<D>

Retrieves the detailed data associated with the given metadata.

fetchMetadataList() → FutureOr<List<M>>

Fetches a list of metadata items available for synchronization.

noSuchMethod(Invocation invocation) → dynamic
