@sunbowen920617 can you try --low-resources-mode? That flag is a more memory-efficient mode that does a lot less caching in memory.

It might be good to get a bit more information about your project though, do you possibly have a few very large files in your project which are a part of the build? It could be just that those files are being cached in memory and causing problems.

having the same issue. By the way, I am trying to understand the custom annotation by cloning this repo "https://github.com/jorgecoca/todo_reporter.dart". I got the issue when I was trying to run the build runner command.

@DayDreamer-commits did you try --low-resources-mode? Do you have large binary files in your project dir?

I'm having the same issue; same when using the --low-resources-flag
Tried it on this project which was referenced in a tutorial and supposedly has worked.

flutter --version

What version of build_runner and analyzer are you using? Check with pub deps. What version of the SDK are you on?

There hasn't been a version of analyzer that uses package:front_end for a while. I don't know why package:front_end would try to allocate a 34GB List instance, but I wouldn't be too surprised if this bug doesn't surface in newer versions of analyzer.

:o
I'm getting

build_runner 0.10.3
analyzer 0.32.6

It's also pulling down front_end 0.1.4+2
Currently on Dart 2.10.0 (build 2.10.0-59.0.dev)

Interesting, I wonder if there is an issue with the old analyzer versions reading the new sdk summary file which causes this? That seems potentially likely - the summary file format did change at one point and possibly it changed in such a way that it somehow gets into an infinite loop when deserializing?

I don't know much about the flatbuffer format or whether that could be possible.

Note that for a while now we have been creating our own SDK summary file instead of using the one shipped with the SDK, for exactly this reason.

Note that I closed this issue under the assumption that upgrading fixes things, but feel free to comment if you are still having issues and we can re-open it.
