getKeys method

CloudStorage getKeys(
  1. void callback(
    1. String? error, [
    2. List<String>? keys
    ])
)

A method that receives the list of all keys stored in the cloud storage. In case of an error, the callback function will be called and the first argument will contain the error. In case of success, the first argument will be null and the list of keys will be passed as the second argument.

Implementation

CloudStorage getKeys(void Function(String? error, [List<String>? keys]) callback)  {
   Telegram.WebApp.CloudStorage
      .getKeys(
        (JSString? error, JSArray<JSString>? keys) {
          callback(error?.toDart, keys?.toDart.map((e) => e.toDart).toList());
        }.toJS,
      );

   return this;
}
