As a developer working with Flutter, you may encounter a frustrating error message ZSH: Command not Found: Flutter when trying to run a Flutter command in the terminal. This error often occurs when the ZSH shell doesn’t recognize Flutter commands and can’t execute Flutter-related tasks.
This article explores the causes of this error and provides troubleshooting steps to resolve it.
What is Flutter?
- ZSH is a popular shell program used on Unix-based systems known for its powerful features and customization options.
- If you get a “Command not Found: Flutter” error message in ZSH, it means that the Flutter SDK is not installed or configured properly on your system.
- Flutter is an open-source UI toolkit developed by Google, used to build natively compiled applications for mobile, web, and desktop platforms.
- You can follow these steps to resolve the “Command not Found: Flutter” error.
- Run “flutter –version” command in terminal to check if Flutter is installed.
- If you don’t have Flutter installed, download and install it from the official Flutter website.
- Make sure the Flutter binary is added to your system’s PATH variable for easy access.
- Restart the terminal or source the .zshrc file for the changes to take effect.
- ZSH is just one of many shell options available, and the “Command not Found: Flutter” error message may be different if you use other shell programs.
In summary, if you get a “Command not Found: Flutter” error from ZSH, it indicates that the Flutter SDK is not installed or configured properly on your system. Following the steps mentioned above will solve your problem and you can successfully use Flutter for app development.
Installing Flutter on macOS/Linux/Windows
If you get a “ZSH: Command not Found: Flutter” error while trying to install Flutter on macOS, Linux, or Windows, follow these steps to troubleshoot.

flutter doctorIt’s in the terminal. If Flutter is properly installed, you will see the status of your development environment.
- Add Flutter to your PATH. If Flutter is not on your system’s PATH, add it manually by editing the appropriate configuration file (such as .bashrc, .zshrc, or .bash_profile). For Zsh users, add the following line to your .zshrc file: bashCopy code
- Refresh Zsh configuration: After changing the config file, reload it by running:
source ~/.zshrcOr restart your terminal.
- Check Flutter installation: Once you’ve added Flutter to your PATH, run:
flutter doctorDouble-check that the errors are resolved and Flutter is ready to use.
Setting PATH variable for Flutter
When working with Flutter, it is important to set the PATH variable correctly so that the shell can recognize and execute Flutter commands. If you see the error message “ZSH: Command not Found: Flutter”, it means your Flutter commands are not recognized by the Zsh shell.
To resolve this issue, follow these steps:
- Find the Flutter SDK installation directory on your computer. The directory where you installed Flutter.
- Open a terminal and run the command to navigate to your home directory.
- to the next
.zshrcThe file is a configuration file for Zsh. You can edit this file using any text editor of your choice.
- the next line
be sure to replace
/path/to/flutter Use the actual path of your Flutter SDK installation directory.
- Save your changes and exit the text editor.
- Finally run the command
source ~/.zshrcApplies changes to the current terminal session.
The bin directory of the Flutter SDK
.zshrc Zsh can find the Flutter command in the file and run it without a “Command not Found” error.
Restart the terminal or open a new terminal window for the changes to take effect.
