💡 Hint

Common Mistakes

Using 'install' instead of 'version' will try to install Flutter again.

Using 'update' is not a valid Flutter command.

Using 'run' tries to run an app, not show version.

Use flutter --version to see the installed Flutter SDK version.

Common Mistakes

Using 'version' only shows the current version.

Using 'install' is for first-time setup, not upgrade.

Using 'doctor' checks environment but does not upgrade.

💡 Hint

Common Mistakes

Using 'check' or 'status' are not valid Flutter commands.

Using 'health' is not a Flutter command.

The correct command is flutter doctor, which checks your setup and shows issues.

4fill in blank

hard

Fill both blanks to set Flutter SDK path in environment variables (Linux/Mac).

C/usr/local

D/home/user

💡 Hint

Common Mistakes

Using FLUTTER_HOME alone does not add Flutter to command path.

Using wrong folder paths will cause commands not found.

We append Flutter's bin folder to the existing PATH variable so the system finds Flutter commands. The path is where Flutter is installed, e.g., /home/user.

5fill in blank

hard

Fill all three blanks to add Flutter SDK path permanently in Windows PowerShell.

Flutter

Drag options to blanks, or click blank then click option'

APath

CC:\src

DFLUTTER_HOME

💡 Hint

Common Mistakes

Using lowercase 'path' instead of 'Path' may not work in PowerShell.

Using wrong folder paths will cause Flutter commands not to run.

This command appends Flutter's bin folder to the user's Path environment variable permanently in PowerShell. The path C:\src is a common Flutter install location.
