Flutter build web command still only builds older version

[psygo]

flutter build web is building the last (and first) time I used it, ignoring the many changes I've made over the last few weeks.

This issue has already been described here:

• [web]: Build web is not working #55008
• [web]: Flutter build web command builds older version of the webapp #75762
• flutter build web command only building master branch in project repo #78912

My Flutter version is the latest, 2.10.4. And you can reproduce this issue by pulling this project, from this commit (72600d7).

I was able to solve the problem, even though it was far from ideal. Basically, I used the recommendations in this comment, creating a new Flutter repo and then copying everything I currently have on top of it.

Hi @psygo, Thanks for filing the issue. I was able to reproduce the issue on the latest stable channel. I tried running the app in debug and release mode and I could see different output.

Debug vs Release

I looked at the web folder and it looks like there are some files that shouldn't have been there e.g (main.dart.js), which are basically generated on building the web app.
so I deleted the web directory and recreated it using flutter create . --platforms web and then I see the same output in debug and release.

Provided that this works fine with a newly created web app, I believe this is not really and issue and we can close it. Incase you disagree feel free to write in the comments and we will reopen it.

I disagree with the closing of this issue.

Provided that this works fine with a newly created web app

The user is not going to use flutter build web only upon the project's creation.

I looked at the web folder and it looks like there are some files that shouldn't have been there e.g (main.dart.js), which are basically generated on building the web app.

How many people are going to be aware of that? I'm not a Flutter beginner and I didn't have the foresight to do it. And, if this repeats itself every time, why not automate it? Why not include these steps inside flutter build web?

@psygo, Sorry if I was not clear what I meant was files in your web directory contains some unwanted build files and those are not added by flutter on running flutter build web. The flutter build command generated files are always under the build/ folder.

I do not mean that you have to run flutter create . --platforms web everytime on project creation. The issue with your sample project was that the build files seem to be mistakenly added to the web folder, Hence the issue.
So I don't see any reason for this issue to be repeated.
