4 years ago I see i am not the first one having this problem. For example i followed a solution from this link: https://github.com/pulyaevskiy/node-interop/issues/67 Which changes something but doesn't work anyway. I have this fragment here now: dev_dependencies: pedantic: ^1.9.0 build_runner: '>=1.6.2 <2.0.0' build_web_compilers: '>=2.6.1 <3.0.0'
dependency_overrides: build_node_compilers: git: url: https://github.com/pulyaevskiy/node-interop.git path: build_node_compilers ref: skip-platform-check-for-node-io
And webdev build produces this error:
[SEVERE] The platform ddc, has already been registered.
[SEVERE] Failed to instantiate builder for args with configuration: {} Unhandled exception: Bad state: Unable to start build daemon.
The second issue/question - still new to dart
dart --version Dart SDK version: 2.10.0-4.0.dev.flutter-0341576448 (be) (Sat Aug 8 20:25:12 2020 +0000) on "windows_x64" There was "pub get" too
In the below main.dart file simple examples work on node.js like Hello World (just command: webdev build). I tried to import some interop packages for testing/learning. As 'package:node_interop/http.dart' as http; was imported correctly (not using it just imported) package:node_io/node_io.dart show some errors, using command webdev build:
build_web_compilers:entrypoint on web/aqueductnodejs.dart: Skipping compiling aqueductnodejs|web/aqueductnodejs.dart with dart2js because some of its transitive libraries have sdk dependencies that not supported on this platform:
node_io|lib/src/directory.dart node_io|lib/src/http_headers.dart node_io|lib/src/stdout.dart node_io|lib/src/network_interface.dart node_io|lib/src/file.dart node_io|lib/src/streams.dart node_io|lib/node_io.dart node_io|lib/src/internet_address.dart node_io|lib/src/link.dart node_io|lib/src/file_system_entity.dart node_io|lib/src/http_server.dart
https://github.com/dart-lang/build/blob/master/docs/faq.md#how-can-i-resolve-skipped-compiling-warnings
Tried different imports like import 'package:node_interop/io.dart'; (seen heere https://www.youtube.com/watch?v=SFY3he2hcXM) , it doesn't work also.
my dart file import 'dart:async'; import 'dart:convert';
import 'package:node_preamble/preamble.dart' as preamble; import 'package:node_interop/fs.dart'; import 'package:node_interop/node.dart'; //import 'package:node_interop/io.dart'; import 'package:node_io/node_io.dart';
//import 'package:node_interop/fs.dart'; // import 'package:node_interop/http.dart' as http;
Future main() async { print('Server test Hello world!'); }

I am asking anybody for helping with this. If it is too compilcated, please don't feel obliged to waste your time. I assume it is not that difficult for experienced users with node_interop libraries. Right now just need it to work for simple tests. Don't need to reach too far.
