With the new release of Dart 2 we've updated the servicestack Dart packages to support Dart 2+.
As this is a breaking change we've changed the major version number of servicestack Dart package to
1.0.5 which can be referenced with:
Where all non-Web (i.e. Flutter, Dart VM, Server and command-line tests) continue to use the same import and
var client = new JsonServiceClient(BaseUrl);
Whilst Dart Web and Angular Dart projects instead use:
var client = new JsonWebClient(BaseUrl);
Both the HelloFlutter and HelloAngularDart example projects (and published docs) have been updated to use Dart 2+ and the latest servicestack Dart packages.
Please refer to the Dart 2 migration guides for how to upgrade your Dart 1.x projects to Dart 2.x. At a minimum it requires changing the
sdk restriction in your
sdk: '>=2.0.0-dev.61.0 <3.0.0'
Normally all changes would be published in the next release notes but the next release is dependent on a new release of VS.NET as it contains support for Xamarin projects being able to the latest ServiceStack.Text which has been modified to use .NET's new efficient
Span<T> types from the System.Memory NuGet package.
I'm on the flutter beta channel and it is running dev.58:
The current Dart SDK version is 2.0.0-dev.58.0.flutter-f981f09760.
and thus the servicestack 1.x release is a non-starter for now.
sdk: '>=2.0.0-dev.61.0 <3.0.0' was based on the Dart 2 migration guide for requiring Dart 2.
The HelloFlutter project works with that constraint although I'm on the
master channel which returns:
Dart VM version: 2.0.0 (Fri Aug 3 10:53:23 2018 +0200) on "windows_x64"
Hopefully they'll release an update on the other channels soon.
