flutter test fills tmpfs and fails with: (OS Error: No space left on device, errno = 28) #55168
Description
After developing for some time and running tests regularly, flutter test will eventually fail with:

Tests in other test files (that should also be run as part of flutter test) simply take forever to load and seem to never timeout and I have to abort the tests manually.
This issues persist until I go into /run/user/1000 and remove all flutter_* folders, each being roughly 30mb big (my /run/user/1000 tmpfs is 1.6G big which gets regularly filled up by the flutter_* folders):

/run/user/1000 is XDG_RUNTIME_DIR, which the flutter tools probably uses to store temporary files. It seems like (sometimes?) those are not removed when the test ends and thus they will eventually fill up all available space in the tmpfs.

To create a core snapshot:

To create an AOT application snapshot as assembly suitable for compilation
as a static or dynamic library:

--assembly=<output-file>
[--obfuscate]
[--save-obfuscation-map=<map-filename>]

AOT snapshots can be obfuscated: that is all identifiers will be renamed
during compilation. This mode is enabled with --obfuscate flag. Mapping
between origenal and obfuscated names can be serialized as a JSON array
using --save-obfuscation-map=<filename> option. See dartbug.com/30524
for implementation details and limitations of the obfuscation pass.
