The constructor was wrapping the onData handler to hide the type-mismatch. This
copies the same logic to the onData handler.
In non-nnbd code this code was not exercised. The migration of dart:async
made this code reachable on our tests. That's because Stream.first used to
do:
var subscription;
this.listen(() => ... cancel subscription here, ...)
it now avoids making subscription nullable by registering the onData handler
later:
var subscrition = stream.listen(null, ...);
subscription.onData(() => ... cancel subscription here);
This change fixes the following 6 html tests under nnbd:
html/history_test/history/history

The least upper bound of _SyncBroadcastStreamController and

to an implicit downcast from StreamController to _StreamControllerBase.
The analyzer and CFE sometimes disagree on the hierarchy depth
computation (see https://github.com/dart-lang/sdk/issues/38377)
which is probably the root cause of this.

Work towards https://github.com/flutter/flutter/issues/46724
Background:
on the latest versions of iOS today, we have to use mdns to discover the observatory port and authentication code. For a variety of reasons this can fail, leaving us with no way to connect.
An alternative approach is to specify the observatory port and disable the authentication code. If binding to this port fails, however, we would still like to attempt connecting with mdns.
Overview:
This adds a new flag to the dart SDK, --enable-service-port-fallback. This amends the behavior of the vmservice with a specified port. After failing to bind 3 times to a non-zero port, update the port selection to 0.
Results:
Tested locally two dart VMs with the same specified port:
```

what closure is registered as listener on the _AsyncStreamController.
There can be two cases:
a) The caller does a regular `foo().listen((_) {})`:
The stack trace will have the closure as the caller and unwinding stops.
b) The caller uses 'await for (... foo())':
In this case the listener will be a StreamIterator.
This CL changes our unwinding code to get the awaiter of `await it.moveNext()`.

The new constructor creates a view of a (sub range) of the elements of another TypedData object.
It works for both typed lists and ByteData.
The advantage over the .view constructors is that it handles other views properly, including their
offsetInBytes in the start computation, which it is easy to forget to do when you call
SomethingList.view(other.buffer)
directly, and that constructor cannot compensate for the information because it only existed on the object
that the buffer was extracted from, not on the buffer itself.

Since a growable list can be created using `[]`, you never need to call
`List.empty` with anything but `growable: false` or `growable: dynamicValue`.
That means that the default should be non-growable (which also matches
`List.filled` and apparently user expectations - since there is already one bug where
I assumed it would be non-grwowble while migrating List.generate).
Ensure it's implemented by dart2js too and used where there were comments
saying to use it when available.

Update/Remove checks of the form:
ReturnType methodName(Type type) {
if (type is! Type) throw ArgumentError(...);
}
Post Dart 2 transition, these checks can now only account for the condition when type is null (though some are redundant with other null checks). Using "is" checks is unnecessary and likely adds a small overhead over a straight null check, in addition to a worse error message.
Since the nnbd SDK declares many of these types to be non-nullable, the checks can be entirely removed. In the regular, SDK I've replaced them with null checks. I'm not sure if this quite follows the intention of the nnbd_sdk.

Type object equality ignores legacy modifiers but preserves other nullability

around the generic parameters themselves.
For example, declaring List<int>, List<int?>, List<int>?, and List<int?>? results
in two top-level classes: ListOfInt(int) and ListOfInt$(dart.nullable(int)).

DDC emits Dart code that can usually be called with the same semantics
as JS there is no guarantee that a function passed to JS and then
invoked successfully was wrapped with `allowInterop`. The wrapping is
always required in Dart2JS. To make DDC more strict, add interceptors
that check for the usage of `allowInterop`.
Whenever a JS interop function or setter is passed an argument which is
statically typed as a Function, but not wrapped with `allowInterop` at
the call site, wrap it with `assertInterop` which will check the
argument at call time and fail with a clear error if it was not wrapped.
Whenever a JS interop function is torn off, either at the top level or
from an instance, wrap it with a function that will also inject these
checks at runtime.
There are still holes where we can't catch the mistake:
- An argument which is statically dynamic and a Function at runtime
won't be caught.
- A Function which is stored in a collection won't be caught.
- A JS interop definition where a getter returns a Function which takes
a Function as an argument is not checked.
- A dynamic call through to javascript is not checked.
Changes:
- Refactor `_isJsLibrary` and add `isJsMember`, and `isAllowInterop`
utilities to determine what needs wrapping.
- Update `assertInterop` to give a more clear error when it fails, and
to ignore non function arguments.
- Add `tearoffInterop` to wrap a function an ensure that any function
typed arguments are wrapped.
- Inject `assertInterop` around Function arguments passed to JS methods.
- Inject `assertInterop` around Function arguments passed to static or
instance JS setters.
- Inject a runtime wrapper around static or instance Function tearoffs.
- Add a test covering all flavors of checks that are supported.
- Change the interop expando to an `Expando<dynamic>` in the NNBD SDK to work
around a stricter type check. https://github.com/dart-lang/sdk/issues/39971
Potential improvements:
If the `tearoffInterop` turns out to be too heavy, we could loosen it so
that we only wrap methods if any of their argument types are statically
declared to be a Function.

Original change was broken by the fact that DDC expects all types marked as
native have all their superclasses marked as native when the super classes are
compiled.
In this case `MapMixin` from dart:collection was not being marked as native and
the only reason it was working before was that the library dependency enforced
the necessary order.
* Now `MapMixin` is explicitly marked as native.
* Added a test case to use some of the API on `window.localStorage` that is
inherited from the MapMixin class.

The front end is failing to consistently find the correct LUB for function types
with generic type arguments (especially with nullability).
We should revert this change after it is fixed.

This change breaks the dartdevc_platform target for nnbd because it removes
the language version comment from only some of the part files in the
dart:_js_helper library. At the same time we need to migrate:
* annotations.dart
* linked_hash_map.dart
* identity_hash_map.dart
* custom_hash_map.dart
* native_helper.dart
* regexp_helper.dart
* string_helper.dart
* js_rti.dart

This is done by collecting all frames on the current stack until an async/async* frame is hit
which has yielded before (i.e. is not in sync-async case).
From there on it finds the closure of the async/async* frame and starts traversing the listeners:
while (closure != null) {
yield_index = closure.context[Context::kAsyncJumpVarIndex]
pc = closure.function.code.pc_descriptors.LookupPcFromYieldIndex(yield_index);
<emit pc in frame>
closure = closure.context[Context::kAsyncCompleterVarIndex]._future._resultOrListeners.callback;
}

This is some preparation for the NNBD migration where the existing downcasts and
possible nullable accesses will be errors.
- Downcasts have been replaced with covariant parameters.
- Local variables have either been declared with a specific type or given
initial values so that they can become non-nullable in the future.
- Remove a pointless `is! int` type check. The parameter is an int.

The goal of this change is to make it possible to start iterating on nnbd tests
for DDC. This keeps the current philosophy of keeping NNBD and non-NNBD build
configurations separate, except that NNBD builds are allowed to consume library
sources from the non-nnbd sdk.
This change addresses the first set of errors that are encountered when trying
to build a fully NNBD configuration:
* CFE has issues with type promotion, for that reason we remove
`--enable-experiment=non-nullable` in vm build rules, and we use a smaller
training data when creating the dartdevc app-jit snapshot.
* We'd hit compile-time errors with nnbd libraries with inconsistent
patchfiles. To avoid that, the libarries.json points to the non-nnbd SDK
sources for most dart:* libraries.
