Flutter app stuck on white screen at start up in android
Hi guys,I am new to flutter,I do have experience in Nadroid development and have even published an apps on the play store. Lately I have been interested in flutter and even did a few introductory concepts on it (CRUD). I took an open source project from github and changed only the google .json file so as to use my fire base backend. The app launches on my android device but is stuck on white screen. I have searched everywhere for this issue but no solution. Its been three days and I am losing my mind. Can anyone help me out here.The open source project is called Fluttergram.

90Hz refresh rate support
There are android phones like OnePlus7 which have 90Hz screens. Today Google revealed Pixel 4 which has a 90Hz screen as well. Also afaik iPad Pro has a 120Hz screen.Do Flutter support these screens to their full potential? Or does the Skia engine cap the refresh rate at 60Hz? Or is there something we need to set in order to allow support for higher refresh rates?

Do Android/iOS widgets work on Flutter web?
I am just starting out on Flutter Web and was trying to get one widget to work for a while until I ran across a comment asking if the widget supported Flutter web.My assumption was that they should work in all formats (that's the point is it not?).Do widgets need to be created specifically to work in Flutter web?
