Dart bindings for web issue with WasiConfig #54
Comments
Solved adding in web/index.html <head>
<script src="/assets/packages/wasm_run/lib/assets/wasm-feature-detect.js" defer></script>
<script type="module" src="/assets/packages/wasm_run/lib/assets/browser_wasi_shim.js" defer></script>
</head> The Readme was saying that is not necessary in flutter web, I was assuming this process was done under the hood, but apparently is not because Fd is requested as import in my binary when using WASI call that have an fd, like fd_seek ecc... |
Created pull request #55 |
This Issue can be closed or should be mutated as "fix flutter scripts injector" |
I think there is something strange with Dart bindings for web:
When I try to setup WasiConfig, the first execution in flutter run -d chrome return an error:
TypeError: Cannot read properties of undefined (reading 'WASI')
.or if I enable captureStdErr
TypeError: Cannot read properties of undefined (reading 'Fd')
.simply doing "r" seems that the "refresh" initialise what failed the first time.
Everything seems to work after but is very strange, because of this issue I gave up with WasiConfig and I decided to "write" by myself wasix import basic like fd_write, fd_seek, clock_time_get, proc_exit so that the config can be null... Any solution? If would be possible to expand the test with loading a valid WasiConfig would be also helpful, because I think my config is set up correctly otherwise the code wouldn't work ever.
Here seems the problem from the debugger, I'm investigating:
