how to fix "bash: flutter: command not found" error?

Question

I have been working on flutter using VScode with all environment variables set on Windows OS. Now i upgraded the flutter using "flutter upgrade" in Git Bash terminal of VScode to the stable version and now i am not able to use flutter commands in Git Bash terminal of VScode. I wonder where things could have gone wrong , how do i fix it ?

I re-verified that all my environment variables are set correctly according to official documentation. Also flutter commands are running perfectly through flutter console .

Ashish@DESKTOP-3JFCI3M MINGW64 ~/Desktop/Flutter Exercise/test_2
$ flutter doctor
bash: flutter: command not found

Edit: Made changes to the "~/.bash_profile" as mentioned by Sam , still getting the same error . Also i re-checked and the environment variables are set there already. Any ideas what i could do further to fix it ? Thanks in Advance :) Also when executed command of step no 3. source ~/.bash_profile , output is

$ source ~/.bash_profile
bash: C:DEVLOPMENTflutterbin: command not found
bash: C:DEVLOPMENTflutterbincachedart-sdkbin: command not found```

Answer 1

It's possible that the environment variable, that was previously set, got cleared at some point and that's why the Flutter command is not recognized.

In any case, one way to make sure that Flutter is in your profile is to add it to your path within your ~/.bash_profile (bash profile) file. The ~/.bash_profile is a script gets executed every time you open Git Bash.

Adding Flutter to your Bash Profile

1. Open your ~/.bash_profile file for editing:

$ nano ~/.bash_profile

2. Add to the top of your ~/.bash_profile file, the following lines:

# Add Flutter to PATH
PATH=/path/to/flutter/bin:$PATH

# Add Dart to PATH
PATH=/path/to/flutter/bin/cache/dart-sdk/bin:$PATH

Replace /path/to/flutter, with the absolute path of your Flutter installation directory.

3. Apply the changes:

$ source ~/.bash_profile
