@override Future<Map<String, dynamic>?> readMap({ required RCacheKey key, })

Method for getting a Map with a defined key.

Example:

Implementation

@override
Future<Map<String, dynamic>?> readMap({required RCacheKey key}) async {
  try {
    Map<Object?, Object?>? value = await methodChannel.invokeMethod(
      RCacheMethod.key.read.map,
      rArgs(type: RCacheMethod.key.credentials, key: key),
    );
    return Future.value(
      value == null ? null : rAutoCastMap(value.cast<String, dynamic>()),
    );
  } on PlatformException catch (e) {
    return Future.error(e);
  }
}
