Flutter Channel Dev 1.15 issue

[furaiev]

I follow the example app, and implement it to my app.
Once publish it, got an issue after create a release version.
After the user session is over (1 hour after), user no longer able to access the app.
the _getValues was throwing error :
"error type '_onebytestring' is not a subtype of type 'int' of 'index'"

I though there's something wrong with my code.
But when I try release the example, the same thing happen.
Secure Counter page & Login page always show "Loading..."

When check it, the actual error came from _cognitoUser.getSession() method.

I honestly don't know what happen here (I'm new to Flutter)
It seem, this issue not happen on debug mode, only when release.

Hi i'm having the same issue when trying to release an apk, everything works fine in debug. My error seems to be triggered by getAwsCredentials from CognitoCredentials:

"type '_OneByteString' is not a subtype of type 'int' of 'index'"

I come from react-native so i'm new to this as well but it'd be great to have some help on this.

Make sure you run Flutter Stable Channel and not Dev Channel.
