Error compiling in Dart - dart

Question

I have a Dart with AngluarDart in local.
Ubuntu 16.04.2
DartSdk v1.23.0
"pub serve" seems work fine
$ pub serve
Loading source assets...
Loading angular2, dart_to_js_script_rewriter and dart_sass_transformer
transformers... (3.4s)
Serving xxx web on http://localhost:8080
Build completed successfully
But when I try to load the web into my browser I get this error:
[web] GET Served 3 cached assets.
[Info from Dart2JS]:
Compiling xxx|web/main.dart...
[Error from Dart2JS]:
web/main.dart:
The compiler crashed when compiling this element.
The compiler is broken.
When compiling the above element, the compiler crashed.
It is not possible to tell if this is caused by a problem in your program or not.
Regardless, the compiler should not crash.
The Dart team would greatly appreciate if you would take a moment to
report this problem at http://dartbug.com/new.
Please include the following information:
* the name and version of your operating system,
* the Dart SDK build number (build number could not be determined), and
* the entire message you see here (including the full stack trace
below as well as the source location above).

I tried to get DartSDK again, revised the PATH...
What can be the problem?

Answer 1

I solved the problem downgrading Dart SDK version.
From 1.23.0 to 1.21.1
Now the complilator do his job without problems.
