Flutter clean and build fail to complete

Steps to Reproduce
I'm not sure there is an exact way to reproduce this issue as it seems to happen at random instances when building or running the project on a physical device.
I hope this is the right place to post this.
Here is an outline of how it occurs.
I have looked at issue #36763 and its not resolving the issue.
You run a project on an ADB connected device. The app will successfully build and/or run on the devices.
Step 1 will randomly get stuck on assembling the project. This will not complete even if you wait for hours(tried it)
Ordinarily when you have a problem you will go for flutter clean . if you try this it gets also stuck for hours with no completion.
Upon inspecting this you find a file in your assembled assets with a number like "8043e5b2" but no extension. This might be an svg, png , or jpeg image which was stripped off the extension and renamed, I found out by looking inside the file or copying it outside of build and adding the extension. This file will not rename, delete or be modified on any application on windows and yes that includes the IDEs.
The only solution that I found to delete this was to boot into safe mode with CMD and delete it from there.
If you pick to go with step 5 you are going to build the app successfully for a couple of times and then it happens again. The you have to go to safe boot to delete the build again.

FacebookActivity could not be started when I have an activity-alias

I have set the icon change dynamically in my app. Icon switching is set with an activity-alias (as described in the Android documentation). After changing the icon, and then changing the activity, login with Facebook no longer works with error "Log in attempt failed: FacebookActivity could not be started. Please make sure you added FacebookActivity to the AndroidManifest". My AndroidManifest.xml is configured as Facebook's documentation. Do you have any ideas? Thank you.
PS. The code I'm using right now is just a test project but partially replicating what's configured in my main project :)

Flutter embedded fragment renders above other views when scrolling

When a flutter fragment is embedded in a native Android application, the rendering of the fragment seems incorrect when it is being scrolled off its parent view.
As you can see the fragment draws over the taskbar, as well as the status bar. (When the fragment is the last item in the list, the button bar is also drawn over in a similar way.)
I have created a repository where this behavior can be reproduced. It is quite straightforward: One of the startup samples of Android, embedding a simple Flutter module. The flutter fragment is inside a CardView that is inside a normal Android ScrollView.

Any ideas of how to set the expected rendering for the flutter fragment?
A workaround seems to be to set the transparency of the flutter fragment to opaque. So call:
FlutterFragment.withNewEngine()
.transparencyMode(TransparencyMode.opaque)
.build();
when embedding it.
This does fix the scrolling behavior, but sometimes shows a black block, when switching between items on the nav bar.
Any other ways of addressing the scroll behavior?

I'd like to install Android Studio in pc which has no internet connection.
I have already downloaded the JDK-7 and the Android Studio using
another laptop.
I have copied the both setup files and successfully installed JDK-7.
Now when i'm running android-studio setup , it requires internet
connection.(step screenshot attached)
Is there any way to skip this step by downloading any other setup(exe) file ?
After downloading all the required files (Development Studio, SDK and Platform), then when you run the Android Development Studio installation, it does not give me an option to select the previously downloaded components, but instead just goes ahead and attempts to download from the internet.

There are 3 main components to a working Android development setup:
JDK (Java Development Kit) Android
SDK (Android SoftwareDevelopment Kit)
IDE (Integrated Development Environment)
First download all three:
Download standalone JDK installer from here, and Android SDK and Android Studio from here.
Now, move the files to whichever machine you want to install your development environment on and install all of them.
The SDK comes packed with only the latest platform (21 at the time of writing) so if you need to use others, you will need to download them separately:
