Dart_PostCObject_DL failed after Hot Restart

[brianquinlan]

I was just hit by it. It never occurred since today and it occurs on Hot Restart, almost at every app launch.

Log

@delfme Could you confirm that this only happens with Hot Restart?

[brianquinlan]

I think that we will have to live with this until flutter/flutter#75528 is fixed.

yes, only hot restart.

this appears to me without hot restart.

for me:

Yea forgot to mention it. To us it occurs with and without hot restart. We have usual 10-20 sec per run

@brianquinlan can we help address this issue? I'm experiencing it almost every minute, making it nearly unworkable on iOS.

Does this still occur with package:cupertino_http 2.0.2?

[iosephmagno]

Thank you! I’ll try version 2.0.2 soon and update you. For now, as a workaround for 2.0.1, we’ve disabled it in debug mode.

[iosephmagno]

Hello @brianquinlan 2.0.2 seems to solve the issue. Thank you!
