Flutter example apps - slow android startup

[purb...@gmail.com]

Hello,

I'm not super expierenced Android developer so please help, I could be missing something. I decided to give Flutter a try nad run into strange problem.

My OS is Arch based Antergos Linux. Installation went quite smooth. I created default Flutter app with Android Studio (the one with plus button and increment counter) and uploaded it from IDE straight to my phone. I heard/read that Flutter apps should start super fast but this is not the case here. This super simple app startup in maybe 15 seconds. I took another phone - same story. When I upload Gallery example from terminal in release mode with commands from

https://github.com/flutter/flutter/tree/master/examples/flutter_gallery

page it's more than 30 seconds for main screen to show up! But the same app installed from Google Play startup almost instantly!

Problem with flutter and/or linux configuration? What am I missing? 

My devices are few years old Android phones but I think it is not relevant here.

I believe you're running into a recent bad regression in startup time which only manifests on certain Android phones:

https://github.com/flutter/flutter/issues/14504

https://github.com/flutter/flutter/issues/14491

Hence why the Gallery you install from the store (which is using an older version of Flutter) doesn't manifest the bug.

We hope to ship a fix soon.
