Understanding Flutter SDK system requirements

Which of the following is NOT a required system component to install Flutter SDK on a Windows machine?

A PowerShell 5.0 or newer

B Android Studio

C Git for Windows

D Windows 7 or newer

💡 Hint

Think about the minimum Windows version Flutter supports officially.

Flutter requires Windows 10 or newer, so Windows 7 is not supported. PowerShell 5.0+, Git, and Android Studio are needed for setup.

Flutter doctor command output interpretation

After installing Flutter SDK and running flutter doctor, you see this message:

[!] Android toolchain - develop for Android devices
✗ Android SDK not found

What does this mean for your Flutter setup?

A Your Flutter installation is corrupted

B Flutter SDK is fully installed and ready for Android development

C You need to install Android SDK to build Android apps

D You must uninstall Flutter and reinstall it

💡 Hint

Focus on what the Android toolchain requires to build apps.

The message means Flutter SDK is installed but Android SDK is missing, so you cannot build Android apps until you install it.

Flutter SDK PATH environment variable setup

Which of the following describes the correct way to add Flutter SDK to your PATH environment variable on macOS?

A Add <code>set PATH=%PATH%;C:\flutter\bin</code> to your <code>~/.bashrc</code> file

B Add <code>export PATH="$PATH:/path/to/flutter/bin"</code> to your <code>~/.zshrc</code> or <code>~/.bash_profile</code> file

C Add <code>PATH=/usr/local/flutter/bin</code> to your <code>/etc/environment</code> file without export

D Add <code>export PATH="/flutter/bin"</code> to your <code>~/.profile</code> file

💡 Hint

Remember macOS uses Unix shell syntax and you want to append to existing PATH.

On macOS, you add Flutter's bin directory to PATH by exporting it in shell config files like ~/.zshrc or ~/.bash_profile with the correct syntax.

Flutter SDK upgrade behavior

What happens when you run flutter upgrade in your terminal?

A It updates Flutter SDK to the latest stable version and updates dependencies

B It deletes your Flutter SDK and installs a fresh copy

C It only updates your Flutter project dependencies, not the SDK

D It resets your Flutter SDK to the initial installed version

💡 Hint

Think about what upgrading a software SDK usually means.

The command updates the Flutter SDK to the latest stable release and updates related dependencies, not deleting or resetting it.

Diagnosing Flutter SDK installation issues

You installed Flutter SDK and set PATH correctly, but running flutter in terminal returns command not found. Which is the most likely cause?

A You forgot to restart the terminal or source your shell config file after setting PATH

B Your operating system does not support Flutter SDK

C Flutter SDK installation is corrupted and must be reinstalled

D You need to run <code>flutter doctor</code> before using Flutter commands

💡 Hint

Think about how environment variables are loaded in terminal sessions.

After changing PATH, you must restart the terminal or run source on your shell config file to apply changes; otherwise, commands won't be found.
