This language feature allows the user to declare a static type using
`extension type` syntax, for example:
extension type IdNumber(int i) {
operator <(IdNumber other) => i < other.i;
bool isValid(Some parameters) => ...;
}
This behaves similarly to a "wrapper" class:
class IdNumber {
final int i;
IdNumber(this.i);
operator <(IdNumber other) => i < other.i;
bool isValid(Some parameters) => ...;
}
However, at runtime, no wrapper objects are created; instead, an
instance of the extension type is represented directly by its
"representation type" (`int` in the above example), and methods like
`isValid` are resolved statically. This gives developers an
abstraction mechanism with the advantage of zero runtime performance
cost, since no extra heap space is required, and no extra instructions
are needed to convert between an extension type and its underlying
representation.
The disadvantage of using extension types as an abstraction mechanism
is that since no wrapper objects are created at runtime, the
abstraction can be bypassed using `dynamic`, runtime casts, or by
"laundering" the object through contravariant generic methods like
`List.add` (which are runtime checked in Dart). For example:
main() {
var id = IdNumber(1);
var list1 = <int>[];
List<Object> list2 = list1;
list2.add(id); // OK at compile time because `IdNumber` is a
// subtype of `Object`. OK at runtime because
// at runtime, `IdNumber` and `int` are
// indistinguishable.
int i = list1[0];
print(i);
}
Extension types are expected to be particularly useful for
low-overhead decoding of external data formats (such as JSON), and for
inter-operation with other languages (such as Javascript).

This identifies all calls to static methods annotated with
`@ResourceIdentifier`, collects the constant arguments passed to the
method, and writes the results into a file.
The purpose of this feature is to be able to pass the recorded
information to packages in a post-compilation step, allowing them to
remove or modify assets based on the actual usage in the code prior to
bundling in the final application.

This language feature allows type promotion to apply to private final
fields, e.g.:
class C {
final int? _x;
C(this._x);
}
f(C c) {
if (c._x != null) {
print(c._x.abs()); // (1)
}
}
Previously the line marked (1) would have needed to be written
`print(c._x!.abs());`.
Note that to ensure soundness, there are certain restrictions:
- Public fields don't undergo promotion (because a public field might
be overridden by a class in some other library).
- Non-final fields don't undergo promotion (because a non-final field
might be modified as a side effect of code executed between the type
test and the field's usage).
- Fields that are forwarded to `noSuchMethod` in the same library
don't undergo promotion (because there's no guarantee that
`noSuchMethod` will return the same value on every invocation). For
example:
class C {
final int? _x;
C(this._x);
}
class D implements C {
@override
noSuchMethod(...) => ...;
}
f(C c) {
if (c._x != null) {
print(c._x.abs()); // ERROR: `c._x` might dispatch to
// `D.noSuchMethod`, in which case there's
// no guarantee that it will return a
// non-null value the second time it's
// invoked.
}
}
- If two classes define fields or getters of the same name, and
promotion is not permitted for one of them, then it isn't permitted
for the other. This is because there might be a class in some other
library that's a subclass of both classes, causing a reference to
one field or getter to dispatch to the other. For example:
class C {
final int? _x;
C(this._x);
}
class D {
int? get _x => ...;
}
f(C c) {
if (c._x != null) {
print(c._x.abs()); // ERROR: `c._x` might dispatch to `D._x`
// (e.g. because some library might declare
// `class E extends D implements C`), in
// which case there's no guarantee that it
// will return a non-null value the second
// time it's invoked.
}
}

This turns on the flags for these two language features and makes
them generally accessible.
Doing so causes a number of tests to fail, but the failures are
approved and there are filed issues for them. Most of the
failures are minor or only affect code using the new language
features.
This CL:
- Enables the features in experimental_features.yaml.
- Re-generates all of the various files generated from that.
- Makes some analyzer and front end changes that this CL
inherited from Paul's original CL flipping all of the 3.0
feature flags. I don't know what these changes are about, but
I assume they are necessary.
- Pins a couple of tests to 2.19 since they deliberately test
behavior that is specific to 2.19. (For most test changes, I've
landed them separately, but there are a couple of stragglers
in this CL.)
This doesn't enable "class-modifiers" or "sealed-types" and doesn't
include the core lib changes related to those.
