installing Flutter in Linux mint :


sudo snap install flutter --classic

it takes some time to download but it says
"flutter 0+git.8cbec5c from Flutter Team* installed"

I was trying to verify that is flutter installed properly or not?


flutter doctor

and the response of the "flutter doctor" command is :
/ has 'other' write 40777

so I found that its some permission issue for flutter

to solve / has 'other' write 40777 for flutter i followed this step :
1. Find where is the flutter


which flutter

I got the path of the flutter install by which command and Flutter is at "/snap/bin/flutter"

2. change the permission of the flutter.
go to the folder where flutter installed by cd command


cd /snap/bin

now change the permission of all files and folders by


sudo chmod 755 /

3. try now flutter doctor in the same directory
and it says


Initializing Flutter
....
....

so it means now it is now in the right direction.

after downloading and installing flutter it says


[!] Android toolchain - develop for Android devices (Android SDK version 30.0.0)
    ! Some Android licenses not accepted.  To resolve this, run: flutter doctor
      --android-licenses
[?] Chrome - develop for the web
[?] Android Studio (version 4.1)
[?] Connected device (2 available)

! Doctor found issues in 1 category.

so i run


flutter doctor --android-licenses

after it starts asking licenses related questions :

Review licenses that have not been accepted (y/N)? y
i typed Y for licenses regarding questions.

now again i run command


flutter doctor

and Finally :


[?] Android toolchain - develop for Android devices (Android SDK version 30.0.0)
[?] Chrome - develop for the web
[?] Android Studio (version 4.1)
[?] Connected device (2 available)

• No issues found!

now all look good!
but I found that I should install addition to the Flutter SDK, which is :

Clang
CMake
GTK development headers
Ninja build
pkg-config


sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev

so i run following command for Linux desktop development :


sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev


flutter config --enable-linux-desktop

Hurry! i completed by Flutter installation.
