I am trying to run my first flutter app emulator, which is having complications at various level, I have tried too much but could not make through it, here is what I have tried.
On trying to click on Create Android Emulator in Visual studio code, the dart extension shows following:-

I don't know why it is happening as on checking, it is present:-

I would like to point out here that I am not able to understand what I have to put in flutter --android-sdk {path}.
Also on running flutter doctor, it shows the absence of visual studio despite the fact that I have it in place(that is why I could take the first screenshot). One thing I would like to point out here is that my vscode is in C drive while my flutter-test folder(which contains everything related to flutter) is in D drive:

Please help so that I can further follow along to create an android app. Also ask if any further information is needed.
You need to know that having Android Studio Installed will solve the majority of issues caused.
STEPS:
Clean out all your Flutter, Dart and Android installation
Download Android Studio from official website (the latest version is Android Studio Electric Eel)
After the installation of Android Studio, open it and add the flutter and dart plugins
Now download flutter and follow the installation steps.
After adding flutter, go to Edit the system environment on your PC and add JAVA_HOME variable with C:\Program Files\Android\Android Studio\jbr. Noticed I used jbr not jre because with Android Studio Electric Eel jbr replaced jre.
Afterward, open new terminal and run flutter doctor --android-licenses
WHAT DID WE DO ABOVE?
We cleaned our installation and downloaded the latest Flutter version which has Dart downloaded automatically. Next, we Installed Android Studio Electric Eel which has Java and Android settings in-build. This way we solve 99% of the problems here: The last thing is to create an Emulator using Android Studio not VSC.
For future help, please comment below. Bye
How to remove error that I have in my project, although the app work fine with me without any problem
This is not an error, this is just showing as error because you are working on a Flutter project. Flutter will never understand build.gradle file. That is why showing as error.
Open your andorid folder as separate project then the error will be gone.
or
Open build.grale file on the top of the file there is an option Open for Editing in Android Studio if you click this option the android module will open in separate window. Now also the error will be gone.
or
Tools -> Flutter -> Open Android Module in Android Studio. Now also the error will be gone.
It is fault in android studio you can't remove this error. Restart your android studio then it'll be gone
I have a problem installing flutter as in the picture and have tried various methods on Google but nothing works, can anyone help me fix it? Thank you.
When I run adb device -l it appears like this:
When I create a project, android studio device can be detected, but when I create a flutter project on android studio device it is not detected:
I have installed flutter and android studio. Followed some resources I have added path.(In windows)
But everytime I run the first project it is giving errors
like. Grandlew bat file not found.
sometimes : exception: exit with 1
Flutter doctor is always giving licenses unknown. I tried number of solutions in the YouTube and from here..but still getting same thing..
My dreams are going to stop in the first step.
you need to install flutter and dart plugin in your android studio/VS code.
to install a plugin in Android Studio follow these steps
Launch Android Studio application
Choose File -> Settings (For Mac Preference )
Search for Flutter then for dart(But dart will be installed automatically with flutter)
I just noticed you don't have Android SDK either, for that, you should go to your android studio and on the top right corner click on the SDK icon, and then install 28/29 version of android SDK hopefully it will solve your problem
alternatively, you can download SDK from here as well
Using Xamarin Forms, when I attempt to launch the Android app in VS2015RC, I receive the following error:
The pre-release version of Android Emulator has expired. Please
upgrade to a newer version.
I have searched the web and am unable to figure out where to upgrade for the latest version?
You can update it from Visual Studio > Tools menu > Extensions and Updates > Updates > Visual Studio Gallery.
Alternatively, you can download it from the Visual Studio Extensions Gallery.
