Looks like a CFE crash. /cc @johnniwinther

alistair-riskmemo · 2024-04-29T01:53:55Z

Hi there, I'm getting the same after running flutter pub upgrade.

huycozy · 2024-04-29T05:48:22Z

Hi @Decodeuprefo and @alistair-riskmemo, I see there was a similar issue at Dart SDK repository dart-lang/sdk#54267 which has been fixed. I'm unsure if it's been landed on Flutter stable 3.19.6 with Dart 3.3.4 yet or maybe this is a regression. So could you switch to the latest Flutter master channel and retry?

huycozy · 2024-05-02T03:40:43Z

@Decodeuprefo You are on Flutter stable 3.19.6. As @alistair-riskmemo confirmed, the issue may be fixed on master channel, please also try on it and confirm. Thanks!

Decodeuprefo · 2024-05-02T05:11:10Z

Yes, I am on Flutter stable 3.19.6. And still facing same issue.

huycozy · 2024-05-02T05:15:50Z

@Decodeuprefo Do you mean you still see the issue on Flutter master channel (3.22.0)? If you haven't checked it on master channel, please use command below to switch to master channel and retry:

flutter channel master
flutter upgrade

Decodeuprefo · 2024-05-03T03:48:44Z

Working fine in master channel. Not facing this issue there.

huycozy · 2024-05-03T04:52:11Z

Thank you for verifying it. Closing this issue as fixed. The fix should land on the stable channel in future releases.

divyanshgandhilm · 2024-05-06T07:29:48Z

@huycozy So should we not switch to 3.19.6 on stable right now? Because I just upgraded and my projects started giving me this same issue.

huycozy · 2024-05-07T03:57:14Z

From the potential commit dart-lang/sdk@fa8e34e that I thought fixed this issue, I see the fix is also available on the latest beta channel 3.22.0-0.3.pre with Dart version 3.4.0 (build 3.4.0-282.3.beta), so you can switch to beta channel which is more stabilized than master channel.

 flutter channel beta
 flutter upgrade
