https://dart-review.googlesource.com/c/sdk/+/116261 :-(

yamdkh · 2019-09-09T04:30:47Z

I did find the start problem of this bug.

the problem dialog appears down when I try to extend a class inside the same file for example

@JsonSerializable
class Employee {
...///
}

class CurrentEmployee extends Employee {}

all in one file and

Notes that I have a file called employee.g.dart for JsonSerializable

Now the problem appears and the error dialog show up with and "dart server analysis terminated "

thanks very much

I was not able to find the root reason of the problem :-( R=brianwilkerson@google.com Bug: #38261 Change-Id: Ib9a78366548688eab231fc941b29f608bdb6b15e Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/116261 Reviewed-by: Brian Wilkerson <brianwilkerson@google.com> Commit-Queue: Konstantin Shcheglov <scheglov@google.com>
