SyncStorageFile class abstract interface

Synchronous companion used by the local engine core.

The engine's hot path is synchronous on purpose: awaiting three nested futures per insert costs more than the insert itself. Remote backends (object stores) get a separate async engine instead of pretending to be a local file.

The hash code for this object.

no setter, inherited

lengthSync → int

Current logical length in bytes.

no setter

runtimeType → Type

A representation of the runtime type of the object.

Methods

appendSync(Uint8List bytes) → void

Appends bytes at the end of the file.

closeSync() → void

Releases the file handle. Subsequent operations throw StateError.

flushSync() → void

Makes previously appended bytes durable.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

readAllSync() → Uint8List

Reads the whole file as one buffer.

readAtSync(int offset, int length) → Uint8List

Reads exactly length bytes starting at offset.

toString() → String

A string representation of this object.

inherited

truncateSync(int length) → void

Cuts the file to length bytes. Must not extend.

writeAllSync(Uint8List bytes) → void

Replaces the file contents with bytes.

Operators

operator ==(Object other) → bool

The equality operator.
