QUESTION
I am using Screenutil package to make my flutter app responsive and it works but I have a problem. Whenever I use splitscreen, the app doesn't rebuild its widgets and they overflow. If I restart the app, it resizes perfectly according to the split screen size. Now, similarly when I exit split screen to full screen mode, the app widgets stay the same size as they were in split screen, until I restart the app. So I want the app to automatically rebuild itself whenever there is a change in screen size. How do I implement this?
Screenutil code:

QUESTION
I have been writting ui for my app, it was ok while building in debug mode. But when I built release apk, UI getting smudged, and Text isn't shown. Widgets are being rendered not as expected and their size being rendered not correctly. I checked it in different phones but result is the same. Is there a problem in my code or it's flutter's inner bug? Has anyone seen this before?
...ANSWER
Answered 2022-Mar-08 at 10:48I found the solution, the widgets weren't rendering because of const constructors of class-based widgets. To resolve this issue there're two ways, first to remove const before widget constructor and usage, second to remove screen_util or another package that generates value dynamically.
Here's the link where I found the original solution https://github.com/OpenFlutter/flutter_screenutil/issues/341.

...ANSWER
Answered 2022-Feb-16 at 00:51You access the .w extension when calling 25.w. This only works when the context inside ScreenUtil is up to date, it doesn't work with an outdated context (from the last build).
The build callback of StreamBuilder updates independently of your Widgets build function.
The StreamBuilder build function is called way more often. Therefore, you have to call ScreenUtil.setContext(context); again to update the BuildContext.
