I recently upgraded my flutter application to Android V2, and also made my code null safe.
Now when I try to run my code I get the below build error:
e: C:\flutter\.pub-cache\hosted\pub.dartlang.org\amplify_core-
0.4.0\android\src\main\kotlin\com\amazonaws\amplify\amplify_core\AtomicResult.kt: (26, 1):
Class 'AtomicResult' is not abstract and does not implement abstract member public abstract

> Compilation error. See log for more details

BUILD FAILED in 15s
Exception: Gradle task assembleDebug failed with exit code 1
Things I tried that did not work:
Clearing build and cache and restarting
Deleted the amplify_core-0.4.0 from the pub.dartlang.org folder and tried again
Initialized Amplify again and pulled the environment from the Launch Studio again
Any help would be greatly appreciated!
Thanks
I was able to solve this issue by changing my channel from Master to Stable.
In the next release of Amplify staying on the Master channel won't present this issue.
