getDescriptors method

Future<List<BluetoothDescriptor>> getDescriptors()

Return a list BluetoothDescriptors for this characteristic.

• May throw SecurityError if the UUID is on a blocklist.

• May throw NetworkError if the device is not connected or if there is an error with the communication.

• May throw StateError if the characteristic is null.

• May throw NotFoundError if the descriptor could not be found.

See: BluetoothDescriptor.

Implementation

Future<List<BluetoothDescriptor>> getDescriptors() async {
  try {
    final descriptors = await _characteristic.getDescriptors();
    return descriptors.map(BluetoothDescriptor.new).toList();
  } catch (e) {
    final error = e.toString().trim();
    if (error.startsWith("NetworkError")) {
      throw NetworkError.withUUid(uuid);
    } else if (error.startsWith("SecurityError")) {
      throw SecurityError(uuid, error);
    } else if (error.startsWith("InvalidStateError")) {
      throw StateError("Characteristic is null");
    } else if (error.startsWith("NotFoundError")) {
      throw NotFoundError.forDescriptor("ALL", uuid);
    }
    rethrow;
  }
