Flutter App rejected, due to WebView not working and Exit/Return key not handled.

[pawangjain]

Hello Tizen Team

We have developed our flutter app on our Samsung TV with the below specs.
Model Code
UA43UE81AFULXL

S/W version
T-KSU2EFUABC-0090-1132.0

Our app plays custom vimeo and youtube videos inside webview_flutter_tizen and it works on our TV we have without any issues.

We submitted it on tvselleroffice and the testers have tested it on the [25TV_STANDARD1 (Tizen 9.0)] TV model QN65Q8FADFXZA with firmware version T-RSLFAKUC-0090-1060.1 and have found the issue as shown on the video at this link.

Below is the tester coment:
"1.Open the app
2. Select any content
Notice:Black screen appears
3. press return
Notice: App does not go back previous page
4.Press exit
Notice: exit button does not work

Notice deffect: App freezes

My Questions:

1. Why would webview_flutter_tizen not work on TV with the software version T-RSLFAKUC-0090-1060.1 ?
2. What is the flutter keycode for the Return and Exit keys of the multikey remote used by the tester as shown in the below image?

We have used the event.logicalKey == LogicalKeyboardKey.escape || event.logicalKey == LogicalKeyboardKey.goBack to handle back key in flutter for the latest samsung remote and the return back button works properly.

Which other key code should we handle in flutter code?

Thanks and Regards.

What is the flutter keycode for the Return and Exit keys of the multikey remote used by the tester as shown in the below image?

On the remote control, the back (return) button is LogicalKeyboardKey.escape. The Exit button is handled internally by flutter-tizen and calls the app_ui_exit() function to terminate the app. There's no need to handle this separately in your app.

Why would webview_flutter_tizen not work on TV with the software version T-RSLFAKUC-0090-1060.1 ?

First, webview_flutter_tizen may not be appropriate for use in production apps. (Please check the limitations.)

The video you attached looks like this.
Running content -> loading text-> white screen (presumably media content loading) -> black screen (player fails to play or app crashes) -> back key(Or here the app crashes)-> Exit key not working(I guess the app has already crashed)

The player may have crashed due to a playback failure, or the app may have crashed while handling the back key in the webview that failed to play.
Since the white screen is expected to be a webview page, it doesn't appear to be a webview creation failure.

We wanted to test the webview on the same TV model the tester tested, but due to internal system issues, we're currently unable to do so. This may take some time.

• Verify that the content resources you provide are valid.
• Check that the back key handling in views containing webviews handles playback failures and other exception handling.
• Currently, we don't have specific data on whether the webview doesn't work on specific boards or models. However, some versions have had issues with the web engine itself. See here (use WebViewController.tizenEnginePolicy).

Could you provide sample code that allows us to test the webview you provide for content playback? If the issue can be reproduced, it would be more helpful for our review.

We wanted to test the webview on the same TV model the tester tested, but due to internal system issues, we're currently unable to do so. This may take some time.

We tested the webview example on the same model(board) of TV the tester tested on. We confirmed that youtube.com loaded normally and some videos played. Please provide a code sample that can reproduce your issue.

If you'd like to test on a wider variety of TVs, you can do so here. https://developer.samsung.com/remote-test-lab
