FakeRfcommTransport class

A controllable RfcommTransport for tests.

Implemented types

• RfcommTransport

Constructors

FakeRfcommTransport({required DeviceId device, required int? channel, required Uuid serviceUuid, int? maxPayloadSize})

Properties

channel → int?

The channel passed to openRfcomm (null if SDP-resolved).

final

device → DeviceId

Which device this transport was opened for.

final

flushCount ↔ int

Number of times flush was awaited.

getter/setter pair

flushDrains ↔ bool

Whether flush models a real drain acknowledgement (Windows, Linux, Android) by zeroing pendingWriteBytes once it resolves. Set false to model the best-effort platforms (macOS/iOS), where flush resolves immediately and the queue drains on its own time — tests then lower pendingWriteBytes themselves to simulate the OS draining.

getter/setter pair

flushError ↔ Object?

If set, flush throws this — models a dead-link flush failure (Windows/Linux/Android throw a BluetoothWriteException there).

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

incoming → Stream<Uint8List>

Inbound bytes. Single-subscription; closes on disconnect (clean EOF).

no setter, override

maxPayloadSize ↔ int?

OS-advertised max single-write payload surfaced as RfcommTransport.maxPayloadSize. Mutable so tests can model any platform: null (the default) for Windows/Linux/iOS, ~1011 for a macOS RFCOMM MTU, ~990 for an Android max-transmit-packet-size.

getter/setter pair, override-getter

pendingWriteBytes ↔ int

Bytes accepted by send but not yet "handed to the OS". Grows by data.length on every send; returns to 0 on a successful flush when flushDrains is true. Also settable, so tests can script arbitrary queue depths and drain timelines.

getter/setter pair, override-getter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sent → List<Uint8List>

Everything written via send, in order.

final

serviceUuid → Uuid

The service UUID requested.

final

state → ConnectionState

Current state.

no setter, override

stateChanges → Stream<ConnectionState>

Connection-state transitions for this channel.

no setter, override

Methods

close() → Future<void>

Closes the channel. Idempotent.

override

deliver(List<int> bytes) → void

Pushes bytes to the connection's input stream as if received.

dropPeer() → void

Simulates the peer dropping the link. Mirrors real backends, which close both the state and incoming streams on a peer-initiated disconnect.

flush() → Future<void>

Completes when all queued bytes have been handed to the OS.

override

nativeStats() → Map<String, int>

A snapshot of this transport's delivery counters.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

send(Uint8List data) → void

Queues data for transmission. Must return immediately without blocking; the platform drains the queue off the calling isolate.

override

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
