flutter/flutter#92134 This PR was supposed to solve our problem. It seems that this was introduced on Flutter 2.10.0 but we just recently updated Flutter on our repositories. I'm checking if we are using the proper version of flutter when building the web folder.

EDIT

This PR only introduced a cache for the canvaskit file. This does not solve our problem.

It seems that the only way to solve this issue is to use an environment variable on --dart-define argument when running Flutter as explained here flutter/flutter#70101 (comment).

So according to the discussion int the PR #74, this is an issue that flutter could fix in the future. For now there is a workaround that could break anytime if flutter change the way canvaskit is handled.

@taorepoara should we apply the workaround for now or should we just wait until Flutter provide a "native" fix ?

Check Flutter V3 and fix for this version if not implemented natively

@lenra-io/devs Does someone remember how to replicate this issue locally ? I tried to launch the devtools while offline, it seems to be working.

I had the problem when I was offline and using the devtool Docker image. I can try to see if the problem remains.

Reproduced with incognito window.

According to this comment on a Flutter issue flutter/flutter#60069 (comment), canvaskit is bundled with the app when you run flutter build web.
I tried to replicate this behavior locally and I found the canvaskit files inside of the build/web/canvaskit folder. This is good news !
To make it work we might want to combine the fact that canvaskit exists in build/web/canvaskit and that we can specify specific canvaskit path when running the app by adding --dart-define=FLUTTER_WEB_CANVASKIT_URL=path/to/canvaskit to the command.

It seems that the --dart-define=FLUTTER_WEB_CANVASKIT_URL=path/to/canvaskit option is not working properly. Another solution is to change the value of the canvaskit url from the index.html file in the web folder according to this comment flutter/flutter#94264 (comment).

Accoriding to the post you linked, the fonts are not working out of the box. But if we follow the link in your comment, we have this : flutter/flutter#60069 (comment)

We should probably wait until it's officially done instead of workaround... What do you think @jonas-martinez ? @taorepoara ?

In my opinion we might not absolutely need this feature. We can wait for Flutter to do the fix on their side, which was planned for Q1 2022 so it might come soon.
