uninstallFilter method

Future<bool?> uninstallFilter(
  1. int? filterId
)

Uninstall filter Uninstalls a filter with given id. Should always be called when watch is no longer needed. Additionally Filters timeout when they aren't requested with getFilterChanges for a period of time. Filter id Returns true if the filter was successfully uninstalled, otherwise false.

Implementation

Future<bool?> uninstallFilter(int? filterId) async {
  if (filterId == null) {
    throw ArgumentError.notNull('Ethereum::uninstallFilter - filterId');
  }
  final params = <String>[EthereumUtilities.intToHex(filterId)];
  const method = EthereumRpcMethods.uninstallFilter;
  final dynamic res = await _client.rpcClient.request(method, params);
  if (res != null && res.containsKey(EthereumConstants.ethResultKey)) {
    return res[EthereumConstants.ethResultKey];
  }
  _client.processError(method, res);
  return null;
}
