Understanding Flutter SDK Path Configuration

When setting up Flutter in VS Code, why is it important to configure the Flutter SDK path correctly?

A Because the SDK path determines the font size in the editor.

B Because the SDK path controls the color theme of VS Code.

C Because VS Code uses the SDK path to run Flutter commands and build apps.

D Because the SDK path is only needed for Android Studio, not VS Code.

💡 Hint

Think about what tools VS Code needs to find to build and run Flutter apps.

The Flutter SDK path tells VS Code where to find Flutter tools needed to create, build, and run apps. Without it, commands like flutter run won't work.

Android Studio Flutter Plugin Installation

What happens in Android Studio after you install the Flutter plugin and restart the IDE?

A You get Flutter project templates and Flutter-specific tools in the IDE.

B Android Studio changes its icon to a Flutter logo permanently.

C The IDE automatically updates your Flutter SDK without asking.

D You lose the ability to create Android projects.

💡 Hint

Think about what a plugin usually adds to an IDE.

Installing the Flutter plugin adds Flutter project templates and tools like Flutter inspector to Android Studio, helping you build Flutter apps.

Flutter Hot Reload Behavior in VS Code

What is the expected behavior when you press the Hot Reload button in VS Code while running a Flutter app?

A The app closes and restarts from scratch.

B The app updates instantly with code changes without restarting the whole app.

C VS Code closes and reopens automatically.

D The app crashes and shows an error.

💡 Hint

Hot Reload is designed to save time during development.

Hot Reload injects updated code into the running app, so changes appear immediately without losing app state.

Running Flutter App on Emulator vs Physical Device

In Android Studio, if you have both an emulator and a physical device connected, what happens when you click the Run button?

A The app runs on both devices at the same time.

B The app runs automatically on the emulator only.

C The app runs automatically on the physical device only.

D Android Studio asks you to select which device to run the app on.

💡 Hint

Think about how you choose where to test your app.

When multiple devices are available, Android Studio prompts you to pick one to run the app on, so you control where it launches.

Troubleshooting Flutter SDK Not Found in VS Code

You open VS Code and try to run a Flutter app, but get an error saying the Flutter SDK is not found. Which of these is the most likely cause?

A The Flutter SDK path is not set or is incorrect in VS Code settings.

B The Flutter app code has syntax errors.

C The Android emulator is not running.

D VS Code does not support Flutter development.

💡 Hint

Check where VS Code looks for Flutter tools.

If VS Code cannot find the Flutter SDK, it means the path to the SDK is missing or wrong in the settings, so it cannot run Flutter commands.
