Channel stable, 1.22.5, on macOS 11.1 20C69 darwin-x64. This happens both to me and to @mvanbeusekom, only after a clean install (app has been uninstalled first) |
|
@BeMacized Thanks for details. flutter doctor -v |
|
@darshankawar which version of the camera plugin are you using? From the screenshot it looks like you are on a pre-0.6.0 version. This error occurs on version 0.6.4 of the camera plugin after which we added the exposure feature. Note that it is a small bug in the code of the example app it self and not the plugin logic. |
|
@mvanbeusekom Tried with the latest camera plugin version |
|
Did you make sure you deleted the App from your test device first? Take the following steps:
I have just reproduced the issue again using version 0.6.4+5. flutter doctor -v |
|
@mvanbeusekom |
|
I don't think it is related to Big Sur, since it happens when running the code on the iPhone itself. @BeMacized has been able to solve it in flutter/plugins#3406, where it looked to be a race condition. It might indeed be related to the iOS version, unfortunately I cannot verify with an older device. |
|
Thanks @mvanbeusekom for replicating. Since I don't have the latest iOS on my test device, I can't replicate it. Also, the PR to fix the issue seems to be ready to merge once approved. |
