installation problem of flutter framework in git-bash - flutter

I'm new to coding and recently tried to install flutter framework in git bash but there was a warning about android studio , by mistake I copied a line of code from the internet
flutter config --android-studio-dir=/my/local/path/for/android/studio
which intern is giving a new warning saying
X android-studio-dir = C:/Program Files/Git/my/local/path/for/android/studio
X Android Studio not found at C:/Program Files/Git/my/local/path/for/android/studio
please, anyone, help me
I tried to write the same code giving the value of the location where the android studio is present but it did not work

Type flutter config -h for help.
It says
To remove a setting, configure it to an empty string.
or you can set the correct value as
flutter config --android-studio-dir='correct/path/'
run flutter doctor when done

Setting up the Android Studio directory on Flutter Doctor

I'm setting up an application development environment with Flutter.
I'm having trouble installing Android Studio: I can't set the directory where Android Studio is installed. I've got an error, as shown in the picture. How do I find the correct directory?
You default Android Studio directory should be C:\Program Files\Android\Android Studio.
If you are searching for the Android SDK location, check out here.
The warning/error you are getting on flutter doctor is telling you that he cannot find Android Studio in the path C:\Program, this means you will need to set it manually. To do it, run the following command(s) with the correct path.
flutter config --android-studio-dir "[YOURPATH]"
flutter config --android-sdk "[YOURPATH]"
This should be the expected output of the flutter doctor
Remember to use those " " to indicate the path of Android Studio, otherwise you'll have this output, that is not what we want: Setting "android-studio-dir" value to "C:\Program".
flutter config --android-studio-dir = C:\Program Files\Android\Android Studio
Which unfortunately does not work because of empty space which breaks the tree structure
To resolve this, type the command below which will reset the default.
flutter config --android-studio-dir=""

Failed to start DevTools: Dart DevTools exited with code 255

I am getting this error code in my Visual Studio Code. How can I fix it?
I am using Flutter v2.5.3.
You can try fixing it by running this in the terminal:
Just copy and paste the below code into the terminal and run it.
dart pub global activate devtools -v 2.8.0
which downgrades the version to 2.8.0 (that works fine). I found the answer on GitHub.
I agree with RandomCoder's answer to avoid executing command
dart pub global activate devtools -v 2.8.0
every time before opening Visual Studio Code.
And also if you didn't know the location of the build folder mentioned by RandomCoder, I found the location after reading it here for the pub cache folder:
By default, this directory is located under . pub-cache in your home directory (on macOS and Linux), or in %LOCALAPPDATA%\Pub\Cache (on Windows). (The precise location of the cache may vary depending on the Windows version.)
After you found it, go to the \hosted\pub.dartlang.org\devtools-2.8.0 directory to copy the build version there and paste it in \hosted\pub.dartlang.org\devtools-2.9.2.
I still didn't know if there is any bad effects of copy pasting it to a newer version folder, but in my case it's working until now.
In my case there wasn’t any build folder in the devtools-2.9.2 folder.
I copied it from 2.8.0 and it now works.
For Android Studio
Close Android Studio
Rn dart pub global activate devtools -v 2.8.0 to downgrade (as suggested in a previous answer)
Open Android Studio
Run your build
For Visual Studio Code
Open Terminal
Run dart pub global activate devtools -v 2.8.0 to downgrade (as suggested a previous answer)
I fix this by:
flutter upgrade
This is an issue coming since yesterday. Maybe they must have updated the Dart engine.
There are two ways which will help you to solve the issue.
Update the Flutter SDK to the latest version and restart your PC:
flutter upgrade
Use the Dart Devtools manually
Run flutter pub global in another terminal. Run devtools and then open http://127.0.0.1:9100
Enter a running application field address of your running application in the Connect: "http://127.0.0.1:60230/J7_wS_YhTuo=/"
You can find this URL in debug console when you run the code.
√ Built build\app\outputs\flutter-apk\app-debug.apk.
Connecting to VM Service at ws://127.0.0.1:51849/mHlycLJYEWw=/ws
If you are getting any issue regarding the port, then do this in your Flutter project console
flutter run --observatory-port=9100
Once the application starts you can see the message in the console.
If you are getting any server issue in the web browser
then enter
dart devtools
In cmd
Downgrade to devtools-2.8.0
And activate using dart pub global activate devtools -v 2.8.0
These two steps worked in my case
First activate your devtool using this command...
flutter pub global activate devtools
flutter pub global run devtools
And after that, try launching it from Visual Studio Code as described in the documentation: Install and run DevTools from VS Code

Set path to Android Studio in Windows

I'm trying to configure the path to Android Studio on my Windows.
I'v tried these commands:
flutter config --android-sdk /path/to/android/sdk
and
flutter config --android-studio-dir /path/to/android/studio
but second didn't work.
I can't change path because it gets cut in cmd.
I've tried to uninstall and re-install flutter SDK, but it didn't fix the flutter doctor errors.
I understood that with ANDROID_HOME already set it was really foolish to implement these commands...
Is this path to android studio correct?
I've zero skills in programming, so I don't even know the basics
run in cmd :
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"

Flutter SDK Is Not Found In The Specified Location

I'm extremely frustrated right now after I updated Android Studio to have the latest Flutter and Dart Plugins. Now it tells me "No FLutter SDK configured" and when I give it the SKD path it just says, "Flutter SDK Is Not Found In The Specified Location." The Dart plugin works fine.
I have looked for an answer for hours and nothing works. I've downloaded the NDK, flutter doctor works perfectly, and I've tried set the SDK path to pretty much every file inside my flutter folder (inside /Documents).
Any tips?
Go to - Configure -> Tools > SDK Manager > Android SDK > SDK Tools, and search for flutter. You will get flutter SDK for Android.
If you are using Visual studio, also install plugins for flutter in Visual Studio.
» Steps:
Download Flutter SDK: Here
Extract Flutter:
tar xf ~/Downloads/flutter_linux_v1.7.8+hotfix.4-stable.tar.xz
Path export for particular terminal:
export PATH="$PATH:`pwd`/flutter/bin"
Permanent Path export:
Open bashrc file: Go to home directory terminal -> nano ~/.bashrc
Write at end of file:
export PATH=" [PATH_Where_Flutter SDK Extracted] /flutter/bin:$PATH"
example: export PATH="/home/sid/0_aaa_iauro/Flutter/s/flutter/bin:$PATH"
Run the following command to see if there are any dependencies you need to
install to complete setup:
flutter doctor -v
Add Flutter extension to vs-code.
Locate Flutter SDK.
Make New project in flutter:
flutter create Project_name

If you are using a fresh new Android Studio install as me, try installing missing packages for SDK support in Android Studio as described here: https://ladwhocodes.blogspot.com/2019/02/fix-flutter-sdk-not-found-in-specified-location.html
Go to Menu > Tools > SDK Manager > Android SDK (left side of the dialog) > SDK Tools (tab).
Select 'Support Repository' and 'NDK' checkboxes.
Click OK.
It will prompt you to install some dependencies. Install them.
What happen to me was because there is a space in my android sdk path (which is my username). I copy to C:\android\sdk and problem gone. Probably the space cause issue to NDK thus affect to Flutter sdk.
in my case, it was caused by local changes to the flutter git repo. On command line, everything worked, but in Android Studio it failed to detected the flutter sdk which caused all flutter commands to fail (even though flutter bin dir is in my path). The local changes were probably caused by trying out the beta version of flutter and returning to stable afterwards.
solution: delete flutter dir and redownload (I actually reverted all changes using the git clean command)

new flutter project in vscode has error

when i create a new flutter project in vscode it will immediately shows an error in the main.dart file and gives a gradle error when trying to debug.
shown here: main.dart error
"compiler message: lib/main.dart:68:19: Error: Too few positional arguments: 1 required, 0 given."
I've reinstalled dart and flutter plugins. updated the java install.
in debug console i get this:
debug console
added output of flutter doctor -v
enter image description here
I was also facing the same error, but it was always on my test folder.
This is what I did:
On your terminal, make sure you are in your project repository.
Run the flutter pub get command, it worked for me, may be you
should try it too.
Do you possibly have two different versions of the Flutter SDK on your machine? I wonder if one is being used by flutter create and the other for analysis.
If you're sure you only have one, please open an issue on GitHub and attach a log file for me to investigate.
