BluetoothGattCharacteristic.fromMap constructor

BluetoothGattCharacteristic.fromMap(
  1. Map<String, dynamic> map
)

从原生 Map 创建 GATT 特征。

参数：

  • map：原生特征数据，无默认值。

Implementation

factory BluetoothGattCharacteristic.fromMap(Map<String, dynamic> map) {
  final descriptors =
      (map['descriptors'] as List<dynamic>? ?? const <dynamic>[])
          .map((item) => BluetoothGattDescriptor.fromMap(_asStringMap(item)))
          .toList(growable: false);
  return BluetoothGattCharacteristic(
    uuid: map['uuid']?.toString() ?? '',
    serviceUuid: map['serviceUuid']?.toString() ?? '',
    properties: _asStringList(map['properties']),
    permissions: _asStringList(map['permissions']),
    value: _asByteList(map['value']),
    descriptors: descriptors,
    raw: map,
  );
}
