What did you do?
When I login line in iOS, my device has installed the Line app but still not login account. The issue is that when navigate from my app to the line app for starting login line account, it automatically switches from line app to the web line for login. I have setup onlyWebLogin variable false but not work.
What did you expect?
When I setup onlyWebLogin variable as false, it will not automatically switch from Line app to web Line.
What happened actually?
Auto navigate to web Line while line app is installed
Your environment?
flutter 3.3.9 flutter_line_sdk: 2.3.5
Doctor summary (to see all details, run flutter doctor -v): [✓] Flutter (Channel stable, 3.3.9, on macOS 12.6.2 21G320 darwin-arm, locale en-VN) [✓] Android toolchain - develop for Android devices (Android SDK version 33.0.1) [✓] Xcode - develop for iOS and macOS (Xcode 14.2) [✓] Chrome - develop for the web [✓] Android Studio (version 2022.1) [✓] VS Code (version 1.74.3) [✓] Connected device (4 available) [✓] HTTP Host Availability
Usually, if your channel app is still under development, this means you are not adding your LINE account as a testing account to your app. Please check and confirm the Developer Console and add your account in the tester list.
You can find the related setting in the LINE Developer Console (login from https://developers.line.biz/), check your channel and invite the LINE account to the tester list.

But when i use the other user line account in iOs, is it necessary for this step?
Only users on this list are allowed to use your channel while it is under development. After you mark the channel to be published, all LINE users can login to your channel.
My channel has been published. But the issue still be here and only happen in iOS when user has not login account in Line app
If the user does not yet log in the LINE iOS app, then it is the expected behavior: LINE app recognize the auth request from the LINE SDK and try to read the login status from itself. If not yet login, then it goes to an error handling process since no login user yet there in LINE.
That's right. Like the android, when navigate to line app for login, i can handle action in app. No need switch to web app
@tuyen3962 Ummm, thanks for the explanation.
I will record this and start a discussion with the team to see if we can improve it. But since it is already a long-lasting LINE iOS app behavior and not directly involved with LINE SDK side, it may take a while before a decision can be finally made. Let me try!
Sorry for the delay of syncing up. With discussion of the team, we think the current behavior is expected and there is no plan to make a change for it currently.
I am closing this issue due to the conclusion. Thanks for the report and your understanding.
