Subject: Change Navigator Pop() code to use Bundle by sending message
X-Git-Tag: accepted/tizen/unified/20221007.171847^0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F37%2F282637%2F1;p=profile%2Fiot%2Fapps%2Fdotnet%2Fsetting-accessibility.git

Change Navigator Pop() code to use Bundle by sending message

- If only Navigator.Pop(), the widget just shows a black screen when
Back button.
- So, changed to use Bundle API and update Content info.
