This CL is part of an effort to bump the SDK requirement to `3.12.0-0`
for all the packages in `pkg` that are not published to `pub`, so that
we can get better testing of the "private named parameters" feature.
(Packages that *are* published to `pub` can't be safely bumped yet,
because SDK 3.12 hasn't been released, and I don't want to block those
packages' ability to publish useful updates to customers.)
This change covers the following packages, which are owned by
OWNERS_VM:
- pkg/dart2bytecode
- pkg/dart2native
- pkg/dtd_impl (jointly owned with OWNERS_DEVTOOLS)
- pkg/mmap
- pkg/observatory
- pkg/vm
Changes to `pubspec.yaml` files were made manually.
Changes to `.dart` files were made automatically, using `dart
fix`. Two kinds of changes were made:
- Migrate to using private named parameters where it is possible to do
so without changing semantics. Note that this migration is
conservative; see https://github.com/dart-lang/sdk/issues/58607 for
details.
- Migrate to using null aware elements.
Tested: Standard trybots
