No active package dhttpd

[asteiman]

Compiling the app seems fine:

However in the logs:

2023-05-05T22:56:38.000000+00:00 app[api]: Build succeeded
2023-05-05T22:57:54.483665+00:00 heroku[web.1]: Starting process with command `/app/dart-sdk/bin/dart pub global run dhttpd --host 0.0.0.0 --path /app/`

Am I missing something?

try to use my buildpack
https://github.com/lovaicv/heroku-flutter

what happened?
No active package dhttpd seem like the package is not activated, if the dhttpd is built successfully, you should see this below message during heroku build.

Built dhttpd:dhttpd.
Installed executable dhttpd.
Activated dhttpd ...

and i saw your dhttpd is restoring from cache, i would advice to download again as it wouldn't rebuild the dhttpd. the way i did is i delete and recreate the heroku app, then deploy again to rebuild.

why this happened?
this buildpack is getting the a version of dhttpd which is not compatible with latest Flutter version which is required null safety, so in my buildpack i upgrade the dhttpd version and modify the dhttpd source.

I am having this same issue. After deploying to Heroku with this buildpack I get the following log output:

Because pub global activate depends on dhttpd from git which doesn't support null safety, version solving failed.
The lower bound of "sdk: '>=2.7.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.

And the server crashes at startup with the following log output:

I tried @lovaicv suggestion with purging the previous build cashes but it didn't fix the issue. It seems that the problem is using a not-null-safe version of dhttpd 🤔 How can I "force" the buildpack to use dhttpd 4.0.0 or later which are null safe?

Sorry, I have stopped support for this repo. I recommend to check readme, I mentioned another buildpack that can be used.

not only you need to purge but you also need switch to use this buildpack, can you confirm that? Inside this buildpack i also modified dhttpd to support null safety

below is the message where dhttpd is built and activated successfully if you use my buildpack

Built dhttpd:dhttpd.
Installed executable dhttpd.
Activated dhttpd 4.0.2-wip from Git repository "https://github.com/lovaicv/dhttpd.git"
