Error I am getting:
When I am trying to build the app (Which is by default app by Flutter), I am facing this problem please someone help me out.
flutter doctor -v:
I also checked the problems but didn't get anything.
I was trying to build the app.
If you are using windows, it is selected windows build by default on VS Code. You can select device on top section for android studio and bottom corner for vs-code.
and then run the app again.
Also you can use command on terminal like
flutter run -d c
this will run on chrome(I am using c to select chrome).
If you like to build on Windows, you need to install Desktop development with C++. Check How to build release version of windows app?

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.
you have to install java runtime environment and It'll work. get from here
it'll show like this if you have JDK installed properly.
I am installing flutter in my windows 10 but when I check that is everything alright through flutter doctor command in cmd then there is some error shown in following picture.

As you can see at the bottom right corner, you don't have an internet connection and thus, it can't reach github.com, which it seemingly needs to run.
Download a fresh install of flutter sdk and follow the necessary steps from here.. https://docs.flutter.dev/get-started/install/windows
Be sure to register the path in the environmental variables
Be sure to install git
Be sure you are connected to the internet along the process
and it should work
Step 1: Download the Flutter SDK. We’ll have to download the Flutter SDK file in order to work with flutter. We can easily download it from the official website of Flutter.click for preview
Step 2: Set Environment variable path. After downloading Flutter SDK, extract the file and copy the path of the bin folder.
click for preview
Press WIN + R and paste the following: rundll32.exe sysdm.cpl,EditEnvironmentVariables
click for preview
Now click on new and paste the path that was copied earlier and save.
click for preview
Now We have to set up the Visual Studio Code for the Flutter. We have to install two extensions in order to use flutter. The very first extension is Flutter and 2nd is Dart. Note that Dart is the programming language that is used in flutter for the application development for both and android and iOS.
Step 3: Installing Flutter in Visual Studio Code
click for preview
Step 4: Now install Dart in Visual Studio Code
click for preview
Step 5: Now we have successfully added Flutter and Dart to the Visual studio code, now let’s check if flutter is installed or not. For this we will open a new terminal in Visual Studio Code and type the following “flutter –version”, if everything is fine then it will normally show the version of the installed flutter.

So basically the problem is that I created a new flutter app, and the I opened the emulator(from android studio), and I clicked on run.
I had multiple problems that were related to heap memory and such, but I managed to solved most of then using all kind of methods from the internet.
I even deleted and installed Java and android studio multiple times, I changed the Enviromental Variables as the Internet suggested, but now, the current error that I get is this:

my flutter doctor -v:

I'm about to lose my mind, I'm on this issuse for a few weeks. please help me fix it
after your seggestion to add "gradle.properties" and adding "org.gradle.jvmargs=-Xmx1024m" to it (without the " "):
after
Perhaps you shoud add a line at end of file gradle.properties org.gradle.jvmargs=-Xmx1024m then clean the project, also validate cache and restart the android studio. It should works then.
I want to develop flutter apps but I don't have enough RAM in my laptop (just 4 gigs). So, after lots of extensive research on the internet, I installed and setup flutter sdk, android sdk and VS Code. But when I try to run a sample app, I can't see list of any available emulators on my VS Code bottom-left screen.
VS Code screenshot (see bottom left).
I am not getting any kind of errors when I run flutter doctor command.
Flutter doctor outputs in powershell.
There's a folder in Drive C where I've installed the Android SDK named as "emulator". There's an executable file named emulator.exe as well but opening it does nothing.
Emulator Folder screenshot.
I also have an external emulator LD Player installed on my laptop but I am not able to connect it with the code editor i.e., VS Code.
Please refer to the links to see the images as I don't have privileges to upload images. I'm a newbie here and this is my first question. Thanks in advance!
You will need to activate ADB settings in your LD Player Emulator.
First, go to settings
Then, select other settings
After that, make sure that you have activated the ADB connection by selecting Open Connection
When I run my application using the VS Code Run and Debug, The app is installed on my device and is stuck on a white screen. Meanwhile in the editor, the VS Code notification is stuck on "Installing build\app\outputs\apk\app.apk..."
I've tried to run different flutter apps on the physical device but was still met with the same error. I've also tried to run the flutter example increment app, but to no avail. I also uninstalled and reinstalled the flutter sdk from the stable GitHub branch but that also did not work. I've also tried solutions from about 22 other questions with similar problems.
However, when I use flutter run from the command line, the app installs and launches on my phone, however, I'm unable to use the Flutter DevTools Inspector.
P.S I've been able to debug flutter apps on the device with the Flutter DevTools in the past.
As of Flutter v1.20.2, this problem has been resolved. The linked GitHub issue is here if you disagree about the problem being solved.
You'll need to end the flutter, dart and flutter processes. So in terminal do this:
killall adb
killall dart
killall flutter
Then reload vscode
