Emulator not running the application – Flutter

I am trying to setup flutter on my device, so far I have been able to download the flutter SDK and android studio and satisfy the conditions of flutter doctor to start learning android application development:-
flutter doctor

I ignored the absence of visual studio as I don’t want my app to be compatible with windows(as I am trying to develop for Android) but I am not able to fix the missing java bundle, any help on how would I do that?

I just ignored it for a second and moved on to set up my emulator but on running, it shows a pop up which says "Attach a debugger or ESC to cancel"(the pop-up is something like this.) how would I fix it.
This doesn’t run the app on the emulator so how would I fix that?

Also on trying to debug, it throws this error, I am totally confused on how to proceed further to at least run my app so that I could start developing and learning flutter?
I am following along this to run my application.

Edit:

I have the java bundle in place but don’t know how would I configure Android Studio to get it.

java’s prescence

Also that the emulator is now showing that the System UI is not responding and on closing it, it further shows this.

It’s been a week since I am trying to work out the setup of flutter but some way or the other some issue happens, please help.

Thanks in advance.
