[Bug] Long dependency graph resolution with nx-rocks/flutter

[lume-code]

Plugin Name

@nxrocks/nx-flutter

Nx Report

Adding nx-rocks/flutter to a large monorepo comprising over 10 apps and 15 libraries resulted in a substantial increase in the time required to resolve the dependency graph (exceeding a minute). Deleting nx-rocks/flutter from nx.json restored the time to less than a second for other projects within the monorepo, which have a similar number of apps and libraries.

Expected Behaviour

Less than a minute just like other nx libs.

Actual Behaviour

Over a minute

Steps to reproduce the behaviour

1. Add nx-rocks to a large monorepo
2. run any build or make any change in .nx.json, project.json and try to build

Hi @lume-code

Thanks for reaching out about this issue.

To help me solve it, can you run the following and report back on the output:

$ nx reset 

then 

$ NX_PERF_LOGGING=true nx graph

and share the output of the last command.

Also, can you provide the output of nx report command.

Thanks

Thanks for the detailled feedback.

Can you run these 2 additional commands ?

NX_PERF_LOGGING=true NX_DAEMON=false npx nx build <your_project_here>
(please share the command output)

NX_PROFILE=profile.json nx build <your_project_here>
(please share the generate profile.json)

Thanks,

I will analyse those and get back to you

Hi @lume-code ,

Just a reminder that I haven't forgotten about this issue. I'm currently rewriting the plugin in a way that should fix perf issue, through usage of caching. It's taking a bit more time, but I should be able to release something soon.

So stay tuned!

[lume-code]

@tinesoft Great to hear that. I appreciate the update :)
