addBool({required bool val}) → MqttClientPayloadBuilder: Add a bool, true is 1, false is 0
addBuffer(Uint8Buffer buffer) → MqttClientPayloadBuilder: Add a buffer
addByte(int val) → MqttClientPayloadBuilder: Add byte, this will overflow on values > 2**8-1
addDouble(double val) → MqttClientPayloadBuilder: Add a 64 bit double
addHalf(int val) → MqttClientPayloadBuilder: Add a half word, 16 bits, this will overflow on values > 2**16-1
addHalfDouble(double val) → MqttClientPayloadBuilder: Add a 32 bit double
addInt(int val) → MqttClientPayloadBuilder: Add a long word, 64 bits or a Dart int
addProtobuf(Uint8List val) → void
addString(String val) → MqttClientPayloadBuilder: Add a standard Dart string
addUTF16String(String val) → MqttClientPayloadBuilder: Add a UTF16 string, note Dart natively encodes strings as UTF16
addUTF8String(String val) → MqttClientPayloadBuilder: Add a UTF8 string
addWord(int val) → MqttClientPayloadBuilder: Add a word, 32 bits, this will overflow on values > 2**32-1
clear() → MqttClientPayloadBuilder: Clear the buffer
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
