BleDeviceCubit class

Cubit for BLE device management

This cubit manages BLE device scanning, connection and communication with GK Concept BLE devices. It emits the following states:

• BleDeviceAuthorizing: when the app is waiting for the user to authorize BLE
• BleDeviceScanning: when the app is scanning for BLE devices
• BleDeviceConnecting: when the app is connecting to a BLE device
• BleDeviceConnected: when the app is connected to a BLE device
• BleDeviceGettingServices: when the app is discovering the services of a BLE device
• BleDeviceGettingCharacteristics: when the app is discovering the characteristics of a BLE device
• BleDeviceFailedToConnect: when the app failed to connect to a BLE device
• BleDeviceDisconnected: when the app is disconnected from a BLE device

Constructors

BleDeviceCubit()

Properties

hashCode → int

The hash code for this object.

no setter, inherited

isClosed → bool

Whether the bloc is closed.

no setter, inherited

mockDevices → List<BluetoothDevice>

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

state → BleDeviceState

The current state.

Methods

addError(Object error, [StackTrace? stackTrace]) → void

Reports an error which triggers onError with an optional StackTrace.

inherited

close() → Future<void>

Closes the instance. This method should be called when the instance is no longer needed. Once close is called, the instance can no longer be used.

connect(BluetoothDevice device) → Future<void>

Connect to a BLE device.

disconnect() → Future<void>

Disconnect from the device

discoverServices() → Future<void>

Discover services of the connected device

emit(BleDeviceState state) → void

Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.

inherited

getRssi(BluetoothDevice device) → int

Get the cached RSSI value of a device.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onChange(Change<BleDeviceState> change) → void

Called whenever a change occurs with the given change. A change occurs when a new state is emitted. onChange is called before the state of the cubit is updated. onChange is a great spot to add logging/analytics for a specific cubit.

inherited

onError(Object error, StackTrace stackTrace) → void

Called whenever an error occurs and notifies BlocObserver.onError.

inherited

startScanning() → Future<void>

Start scanning for BLE devices.

stopScanning() → Future<void>

Stop scanning for BLE devices.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Properties

logger → Logger
