BleDevice.fromMap constructor

BleDevice.fromMap(Map map)

Converts a Map to a BleDevice object.

The map, which contains information about the discovered Bluetooth device, comes from the plugin's method channel. Therefore, the type annotation is <dynamic, dynamic>.

Implementation

factory BleDevice.fromMap(Map<dynamic, dynamic> map) {
  // Parse the manufacturer data from the string if it exists.
  final String? manufacturerDataString = map['manufacturerData'] as String?;
  ManufacturerData? manufacturerData;
  if (manufacturerDataString != null && manufacturerDataString.isNotEmpty) {
    manufacturerData = ManufacturerData.fromString(manufacturerDataString);
  }

  // Get the advertised service UUIDs, which is a list of strings.
  final List<dynamic>? advertisedServiceUuidsDynamic = map['advertisedServiceUuids'] as List<dynamic>?;
  final List<String>? advertisedServiceUuids =
      advertisedServiceUuidsDynamic?.map((dynamic uuid) => uuid as String).toList();

  return BleDevice(
    name: map['name'] as String?,
    address: map['address'] as String,
    advertisedServiceUuids: advertisedServiceUuids ?? [],
    rssi: map['rssi'] as int,
    manufacturerData: manufacturerData,
  );
}
