How to use it with dart libraries that dependes on dart:io?

[shinayser]

Hello!

I am trying to develop a bot for Telegram and I am using the teledart library from pub dev. But it depends on dart:io since it does some network calls.

There is a way to make it work?

Looking at the code in teledart repository you'll have to fork it and replace all usages of dart:io with corresponding alternative in node_io package.

Also (luckily) teledart uses package:http which is implemented by node_http so you'll need to replace all usages of it with node_http.

Hopefully this is all that's needed. But there is a chance they use some APIs not covered by this library yet. In which case feel free to let me know and I'll try to help.

THanks for you answer @pulyaevskiy!

So to wrap up: I have to fork the library changing the packages to node correpondents and do it recursivelly for each libraries that those packages may depend on?

I went for a different path, using conditional imports and seems to be working until I tried to compile it.
Unfortunatly not all the http and io library features are implemented. I tried to compile to javascript using the node compilers and this was the some of the errors:

Error: 'MultipartFile' isn't a type.

                                                          ^^^^^^^^^^^^^
Error: Method not found: 'MultipartRequest'.
    var request = http.MultipartRequest('POST', Uri.parse(url))
                  ^^^^^^^^^^^^^^^^

    Future<dynamic> serverFuture = io.HttpServer.bindSecure(
                                                 ^^^^^^^^^^

Error: Method not found: 'SecurityContext'.
    _context = io.SecurityContext();
               ^^^^^^^^^^^^^^^
Error: Getter not found: 'anyIPv4'.
        io.InternetAddress.anyIPv4.address, port, _context);
                           ^^^^^^^

The teledart library uses a lot of those MultiPart files requests...

Tehre is any workaround you can insight me ?
