[Michael Thomsen]

The first release candidate, RC0, of version 1.14 of the Dart SDK is now
ready for testing. This release candidate is version 1.14.0-dev.7.2 from
the dev channel. Please download it

The release contains a number of improvements to the core library, and

Pub has been updated with several improvements and fixes. Please note that
the changes to pub include two breaking changes:

-

Package names have stricter validation.

Support for barback versions prior to 0.15.0 (released July 2014) has
been dropped.

more details about the API changes. We look forward to your feedback

I wonder why some really great changes are not even mentioned in the

I was wondering what is the status of using no packages symlink now, and if
there are changes to the new js interop for 1.14.

There is a hidden option to pub, --no-package-symlinks, which will
create only a .package file, not a package directory.
We want to do more testing before it is the default, and the test
package does not work well with it yet, but
everything else should be working if you use it. I have taken a web
project, and used pub to get, build, and serve
without package directories, and it works well.

Other people who know more should be able to give more detailed
answers on the status of this change, and on the changes to
js-interop.

I would *strongly advise* against using the --no-package-symlinks flag
right now, which is why it's not (yet) visible. It will almost certainly
break any packages that rely on the existing package infrastructure for
introspection or asset-loading.

Maybe worth noting that https://pub.dartlang.org/packages/resource is a
thing now since that was removed from the core.

[Ray King]

+Natalie on this one....

It also breaks Flutter projects... --no-package-symlink is just ready for
primetime.. When it is I will be the first change, at moment, somestuff
will run but most of cornerstone stuff like test just bombs out.

From what I have seen, the issues blocking the test package from working
with `--no-package-symlinks` were fixed recently, but the test package
needs yet to be updated to make use of the updated API.

moving from package symlinks to the .packages file. Stay tuned!

flat_buffers have been implemented as an implementation detail within the
analyzer. The implementation (at least up to now) has not been done with
the goal of general reuse, but it could (at least in theory) be.

It'll be up to the analyzer team –

This is working quite well already. Some core APIs (Map, Stream, ...) have
these comments added already and the analyzer provides great feedback.
What was a bit annoying that flattening Future wasn't handled yet properly,
but from what I have seen this is also fixed (not sure if it's in latest

No, not yet. It was postponed again, it was mentioned that it should make
it into early 1.15-dev versions.

Having Segmentation fault issues with raspberry pi zero armv6, has support

Would be nice to have dart support and or fletch for the pi 1 and pi zero.

FAQ has armv6 as supported.

I tried a server/standalone test with the timezone package and got an error.
"Unhandled exception:
The null object does not have a getter 'isNotEmpty'."

https://pub.dartlang.org/packages/timezone
I not using this package but like to run it on new releases.

Issue is the packageRoot returns null instead of empty string now.

api change from
https://api.dartlang.org/1.13.2/dart-io/Platform/packageRoot.html
If there is no --package-root flag, then the empty string is returned.
to
https://api.dartlang.org/135942/dart-io/Platform/packageRoot.html
If there is no --package-root flag, then null is returned.

Seems fine now after changing the test from packageRoot.isNotEmpty to
packageRoot?.isNotEmptyI in standalone.dart file.

if (packageRoot.isNotEmpty && p.startsWith(_packagesPrefix))
to
if (packageRoot?.isNotEmpty && p.startsWith(_packagesPrefix))

Is this the best way of handling the issue?

I get around to creating an issue for timezone package.
