Support Wasm Compilation

Support Wasm Compilation

Closed this issue 3 months ago · 7 comments

Is it possible to support compiling to Wasm when using packages like super_clipboard and super_drag_and_drop? I tried compiling it against Wasm but it fails with ffi.

           ../../../../.pub-cache/hosted/pub.dev/super_native_extensions-0.8.22/lib/src/native/data_provider_manager.dart:2:1:
Error:
           'dart:ffi' can't be imported when compiling to Wasm.
           import 'dart:ffi';

What error do you get exactly? And which version are you using? The ffi should not be using during wasm compilation.

I updated the issue description with the error I am getting. I am using the latest version 0.8.22.

I see. I think using dart.library.js conditional import is what broke recently. I probably need to use dart.library.js_interop instead.

That could be one of the issues but I am seeing a lot of 'dart:ffi' can't be imported when compiling to Wasm. errors coming from super_native_extensions.

That is expected with conditional imports not working.

@knopp Created a PR that replaces all usages of dart.library.js with dart.library.js_interop. Please take a look.

@knopp I can confirm that this now compiles to wasm without any issues.
