I'm currently making an app for Android with Flutter, and I'm using google-mobile-ads package to show banner ads.
My environment is VScode & Android emurator by Android Studio.
To run this project Execute this command:
$ flutter run --no-sound-null-safety
Not with Play button.
However if I run with this command, hot reload is disabled. Any edits don't make any changes.
flutter doctor -v;

How can I make this possible?
When using flutter run you should be able to hot reload pressing r and to hot restart using R. Just press them in the terminal where you've used flutter run.
If I remember correctly, launching flutter run you should get all these info on the console as a message when starting!

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 :)
Change Icon and Facebook login functions

! Doctor found issues in 1 category.
i show only error message.
What i can do to fix this problem ?
I already tried to flutter clean, flutter pub cache repair, restart laptop, reinstall android studio, and reinstall android emulator.
I'm new to flutter dev and android studio, so basically whenever i run my app on windows(desktop), my app opens for 20sec on windows but then gets closed automatically.
It shows :
"LOST CONNECTION TO DEVICE" ,
I don't know what is the problem !? I didn't even have the app.so file present in any folder, I had to ask a friend to mail me this file, and even after pasting the file in the
build->windows->runner->debug folder, it's showing the same error.

In Android Studio, I get this error message when trying to start a new Flutter App.
Android Studio error message
I can't figure out why it's not working. I can run the default Android Studio flutter app in the Android Virtual Device fine.
?
same thing happened to me when i pointed the path
as
/home/ekele/flutter_sdk/bin
it worked when i changed it to
/home/pompidou/flutter_sdk
change the path below to C:\Users\kaste\Documents\flutter
As said before, you need to set 'flutter installation directory' (you got it as can be shown at your flutter doctor -v command output:
Flutter version 2.2.0 at C:\Users\kaste\Documents\flutter.
Problem is you are setting as flutter SDK your Android SDK installation directory, which is wrong. You need to just set C:\Users\kaste\Documents\flutter instead of C:\Users\kaste\AppData\Local\Android\sdk
