Casual Discussion: How far have you/your project/crusade for "Flutter for Enterprise" progressed?
So in my line of work (IT-consultant) we engage with clients and build/make the apps they want. Usually with proper backend APIs, infrastructure and the whole package.On our monthly tech calls there's been mentioning of Flutter during Q&A, but the response is in general that the Flutter framework is being observed and evaluated but not put before clients as a solution (instead of ReactNative et al) until there's specific customer interest or other successful projects in the market.I'd just thought it be interesting to see what the overall sentiment from other devs or PO is on this subject, specifically in the enterprise domain (or B2B apps).

Launching Flutter app into background
I have Flutter app that performing long running task in background using BLE.I'm using Core Bluetooth to perform State Preservation and Restoration, which is waking app on BLE signal if it was terminated by iOS routines.The problem is that when iOS launch my app directly into background, I get following error:GLDRendererMetal command buffer completion error: Error Domain=MTLCommandBufferErrorDomain Code=7 "Insufficient Permission (to submit GPU work from background) (IOAF code 6)" UserInfo={NSLocalizedDescription=Insufficient Permission (to submit GPU work from background) (IOAF code 6)}Is there a way to start Flutter somehow "heedlessly", so it won't try to use GPU?

SERIOUS BUG of flutter on iOS !
flutter is very popular these days , so i looked for some apps on app store and installed them on my iphone xs 、iphone x and two android phones,then i found a serious bug on ios phones, that is : if you turn the app to background, after a short time, you open this app again and slide on a page of app ( especially a page contains listview ), you will find a serious janky ( skip frame ) happens( maybe not happen every time, but the probability at least 90%), slide over some distance , the janky will disappear.at first, i thought this happens because of a bug of the app , but after i tried many apps , EVERY app has this bug , i came to the conclusion : flutter has a SERIOUS BUG on iOS platform.anyone who has question for my opinion can just try the apps on : https://itsallwidgets.com/because of this bug, i'm confused, i dont know if i shoud continue to use flutter to develop.
