Read data from mongodb via GraphQL

Question

Hello,

Can you please advise how I can display the events stored in my mongo db via graphql? I've managed to find the way to add the events, but I can't quite figure out how I can read them and display in the calendar?

Thank you in advance!

Maria

Thank you, this is what I've tried to do (using graphql_flutter packager), however it looks like flutter can't cast query into list.List appointments = Query(
      options: QueryOptions(document: gql(_getEvents)),
      builder: (result, {fetchMore, refetch}) {
        if (result.isLoading) {
          return const CircularProgressIndicator();
        } else {
          result.data!["events"];
        }
        throw const Text('Something happened');
      }) as List;
  return _DataSource(appointments);
}
