Having trouble setting flutter path - flutter commands not found

I'm using Ubuntu 18.04 LTS. Assuming you have successfully downloaded and extracted flutter_linux_v0.5.1-beta.tar.xz (latest update until now) onto your preferred directory.

export PATH=`pwd`/flutter/bin:$PATH 

Running this command in your ubuntu terminal (Ctrl + Alt + T) adds flutter commands PATH variable to your system path for temporary session. As soon as you close the terminal, the system path is removed.

In order for ubuntu terminal to remember flutter commands permanently, you need to:

1.) open up terminal and cd to $HOME. for eg: user@linux:~$

2.) open the hidden file .bashrc with your desired editor. It resides in $HOME.

3.) add the following line export PATH=/home/yourname/flutter/bin:$PATH somewhere as a newline in .bashrc file preferably as a last line edit & save file.

4.) run source /home/yourname/.bashrc in terminal to process your recent changes.

5.) finally, run echo $PATH to see flutter dir is in your system path along with other such paths. for eg: /home/yourname/flutter/bin

Now close current terminal and reopen new terminal to check flutter doctor. It should process along with all other available flutter commands everytime now onwards. Thank you ! :)

Windows
Refer to this tutorial https://www.java.com/en/download/help/path.xml

Mac OS
Open or create one the following files:

• ~/.profile (Compatible with MacOS Catalina)
• .bash_profile (Only if your Terminal uses Bash)

export PATH=$PATH:/flutter/bin 

Linux
Open or create ~/.bash_profile add the following line at the bottom.

export PATH=$PATH:/flutter/bin 

Linux (Ubuntu 19.04)
Open ~/.bashrc add the following line at the bottom: (your path may be different)

export PATH=$PATH:~developement/flutter/bin

I'm using macOS Catalina version- 10.15.7 and I have updated my $PATH variable by following those steps:

1. Optional: Type echo $SHELL in your terminal. It will tell you which shell you are using. macOS Catalina uses Z shell by default. Output: /bin/zsh
2. Optional: Type echo $PATH in your terminal and hit enter. It will show you the existing paths you have already set as path variable. Output: /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/go/bin:/Library/Apple/usr/bin
3. As i'm using Z shell i have to open the .zshrc file. In my case i'm using vim editor. You can also use nano or atom editor. For opening the file type vi ~/.zshrc in your terminal.
4. Type i for Insert mode.
5. Type export PATH="$PATH:[your_flutter_sdk_path_here]/flutter/bin"
6. To save the file in Vim/vi, press Esc key then type :w and hit Enter key.
7. To quit Vim/vi by press Esc key then type :x and hit Enter key.
8. Finally you need a dot notation to activate it. Type . ~/.zshrc in your terminal.

Now you can check your path variable by typing echo $PATH in your terminal and hiting enter key.

Output: /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/go/bin:/Library/Apple/usr/bin:/Users/user/Documents/flutter/bin

Verify that the flutter command is available by running which flutter in your terminal.

Output: /Users/user/Documents/flutter/bin/flutter

export PATH=`pwd`/flutter/bin:$PATH 

I had the same issue when i am working VS Code / flutter with ubuntu OS. every time shows the message flutter: command not found . Then i set the path through VS Code integrated terminal. Please see the below screenshot.

open a terminal window and write command vim ~/.bash_profile Write this in the file.

alias flutter="~/flutter/bin/flutter" 

if you have extracted flutter in your root (~) folder.

save this and run this command in terminal.

source ~/.bash_profile 

Now you are done.

You can add the Flutter path to the system path or to your ~/.profile file.

This will help you as it has more detailed instructions, difference on using .profile vs .bashrc and usage on different shells.

Flutter Path Setup in MAC

Before Setup Clone the git Flutter Folder using below Command

==> git clone https://github.com/flutter/flutter.git -b stable

Step 1: Copy the Path of " Git Flutter Folder" and make PATH variable like below

==> export PATH="$PATH:/Users/myhome/Desktop/Flutter/bin"

Step 2: type "echo $SHELL" in terminal.It will show the type of shell which is using in your Mac

Step 3: If it is bash, type "open .bash_profile" in terminal to open the hidden "rc" file

step 4: once opened, copy the Path variable from step 1 and paste it in .bash_profile file

Step 5: save the file

Step 6:run ==> source $HOME/.bash_profile

Step 7: Now check your path got updated by ==> echo $PATH command

Step 8:once it got listed run ==> Flutter Doctor

Step 9: If error occurs like "flutter commands not found" then "RESTART" your Mac

Now try Flutter Doctor it will work

it depends what shell you use,if you use bash,you can edit ~/.bash_profile,add environment variable as export PATH=xxx/flutter/bin:$PATH;if use zsh,you should edit ~/.zshrc ,add environment variable as export PATH=xxx/flutter/bin:$PATH

For bash profile users

Step 1: open terminal and type

vim ~/.bash_profile 

Step 2: Type this command (modify your folder path)

Note: I added one new folder(FlutterSDK) in my username

export PATH="$PATH:$HOME/FlutterSDK/flutter/bin" 

Step 3: Press esc

Step 4: type :wq! command to save this bash file

:wq! 

Step 5: Close current terminal window & open new window

Step 6: To verify type flutter version command

flutter --version
