I want to show select language dialog when app opened for first time.
I have taken ver. Arrang. For selection of language with 3 buttons as 3 languages.
Set as non visible.
Another 3 vertical scroll arrangements are taken, set non visible, and makes visible, when selected any one of the language.
It is working when i open app for first time.
Suppose i selected button1 then, this language dialog will disappear and vertical scroll arrangement1 will appear, data stored with tinyDB.
When i open app for second time then vertical scroll arrangement1 should appear but not appearing, blank screen is appearing.
In your procedure, you are setting your “vertical_arrangement1” visibility to FALSE when the app is open for the second time. I think you should put in the ELSE condition “vertical_scroll_arrangement1” visible to TRUE.
