In IntelliJ the debugger stopped at an exception and after about 20 sec the app crashed with

How easy is to reproduce this crash, @zoechi ?

aam on 14 Aug 2018

Haven't seen this in a while.
I'll reopen if I encounter it again.

GRouslan on 8 Sep 2018

I am also seeing the exact error posted by @GRouslan . @GRouslan are you using built_redux? my errors are occurring in the built_redux middleware.

jadengis on 10 Sep 2018

Yes

GRouslan on 11 Sep 2018

I'm using built_redux as well.

zoechi on 11 Sep 2018

Thanks for the report. We'll try to reproduce this.

kmillikin on 11 Sep 2018

is there a way you can extract small repro for this @zoechi @GRouslan @jadengis ? I tried building small app with flutter_redux (0.5.2) and it seems to work fine and I am able to debug it as well.

aam on 12 Sep 2018

It didn't happen for me anymore since a while, so I'll leave this to @GRouslan @jadengis

zoechi on 12 Sep 2018

@aam This error is occuring for me with the built_redux v7.4.5 and flutter_built_redux v0.6.0, and I have experienced it in a couple projects when i put a breakpoint in one of the libraries Middleware closures.

I could try to put together a simpler reproduction case. Unfortunately, both of the projects where I have seen this issue are private.

jadengis on 12 Sep 2018

I will post here this week as soon as I extract code essence.

GRouslan on 12 Sep 2018

Thank you folks in advance!

aam on 12 Sep 2018

handshakes_strip.zip

Put breakpoint

Start in debug mode
Press button

It happens only after first click

Thank you @GRouslan !
Here is extracted repro t.dart:

abstract class Built<V extends Built<V, B>, B extends Builder<V, B>> {
}

abstract class Builder<V extends Built<V, B>, B extends Builder<V, B>> {
}

class MiddlewareApi<
    State extends Built<State, StateBuilder>,
    StateBuilder extends Builder<State, StateBuilder>> {
}

main() {
}

run this via out/ReleaseX64/dart --observe --pause-isolates-on-start t.dart
Open observatory, set a breakpoint in main(), resume, once paused on breakpoint navigate to MiddlewareApi class and request evaluation of 'toString()' expression. This fails with

I looked at it further and have thoughts on how to fix it here: https://dart-review.googlesource.com/c/sdk/+/75241

cc @jensjoha @kmillikin

aam on 18 Sep 2018

The fix landed in dart sdk as well as in Flutter (master branch).
