Hey, currently I dont seem to be able to find a way to give req and res in Future<void> start(final req, final res) a type which is pretty annoying. Are there any types for req and res I can use?`Something like AppwriteRequest or AppwriteResponse

Summary

There is currently no built-in type support for req and res in Dart cloud functions. However, you can use a workaround by defining your own AppwriteRequest and AppwriteResponse classes. Here is an example implementation: ```dart class AppwriteRequest { final Map<String, dynamic> variables; final Map<String, dynamic> headers; final String payload; AppwriteRequest({ this.variables = const {}, this.headers = const {}, this.payload = '', }); } class AppwriteResponse { int _status = 200; dynamic _text; int get status => _status; dynamic get

We've had discussions about exposing the types. For now, maybe you can copy and paste this and cast the variables in your function body.

Casting doesnt work, 'im getting type 'Response' is not a subtype of type 'AppwriteResponse' in type cast'

class AppwriteRequest {
  final Map<String, dynamic> variables;
  final Map<String, dynamic> headers;
  final String payload;

  AppwriteRequest({
    this.variables = const {},
    this.headers = const {},
    this.payload = '',
  });
}

class AppwriteResponse {
  int _status = 200;
  dynamic _text;

  int get status => _status;
  dynamic get body => _text;

  AppwriteResponse send(String? text, {int status = 200}) {
    _text = text;
    _status = status;
    return this;
  }

  AppwriteResponse json(Map<String, dynamic> json, {int status = 200}) {
    _text = json;
    _status = status;
    return this;
  }
}

Womp. It still might be possible with a lot of hacking...

Yep, got it to work with this fancy hacky method:

T? castOrNull<T>(dynamic x) => x is T ? x : null;

  AppwriteRequest? req = castOrNull<AppwriteRequest>(requ);
  AppwriteResponse? res = castOrNull<AppwriteResponse>(resp);
