The documentation of IOSync states that calling flush on a closed IOSink may have no effect:
https://github.com/dart-lang/sdk/blob/main/sdk/lib/io/io_sink.dart#L109
The future returned by close in the new implementation does not complete until after
a call to flush has completed.
The previous implementation of File.open did not throw when calling flush after close.

The usual approach:
Pure interfaces marked `interface`.
Pure implementation classes marked `final`.
Base classes marked `base` or nothing, and `mixin class` if reasonable.
Combined X/XBase/XMixin where possible.

All calls on records are no longer treated as essentially dynamic calls. So a call to `record.foo` will not pull all `foo` members into the program (including unused ones). For example in the below test the getter `any` was causing `JSArray.any` to be included in the program. After this change it is no longer pulled in.

Although the true branch of `x != null` and the false branch of `x ==
null` promote `x` to non-nullable, the opposing branches do not promote
`x` to `Null` in the current flow analysis spec, which applies to the
CFE.
When switching from the dart2js static type computation to the CFE
static type computation, attempting to use `x` in these branches may
generate an unintended type check, which can overflow the stack if this
occurs in code responsible for performing type checks. The fix is fairly
straightforward - we can simply use an unchecked cast (via `JS`) instead.
See https://github.com/dart-lang/language/issues/1505 for discussion on
why the expected promotion does not (yet) occur.

Adds class modifiers to `dart:ffi`.
Migrates all user-defined subclasses of `Struct`, `Union`, `Opaque`,
and `AbiSpecificInteger` to be `final class`es.
Does not remove the manual error checking, so some errors will show up
twice now in language version 3.0. In language version <3.0, only the
FFI-specific error will show up.
In a follow-up CL, we will try to make the language-errors to show up
also <3.0 so that we can remove the FFI-specific errors.
Examples of duplicated errors:
pkg/analyzer/test/src/diagnostics/subtype_of_ffi_class_test.dart
TEST=pkg/analyzer/test/ (for the analyzer)
TEST=pkg/front_end/testcases/ (for the CFE)
TEST=test/ffi/ (for the VM)

worked just because there was no reason to make them nullable.

This uses the context type when creating the space for a cast pattern
to include the implicitly covered subtypes in the space. This is done
when the context type is a sealed type which means that we can reason
about which of the subtypes of the sealed type that are implicitly
handled by the throw of the cast.
