Flutter Setup Guide

Install the Flutter SDK and run your first app on an emulator or real device.

terminal

# Download from https://docs.flutter.dev/get-started/install

What it does

The Flutter SDK includes the Dart language, the framework, and the `flutter` command-line tool.

Why you need it

Everything you build with Flutter runs through this SDK — it compiles your Dart code to native apps.

Alternatives: On Mac/Linux you can install via `git clone` of the Flutter repo and add it to your PATH.

terminal

flutter emulators --launch <emulator_id>

What it does

You need somewhere to run your app — an Android emulator, iOS simulator, or a physical phone.

Why you need it

Without a target device, there's nothing to display your app on.

Alternatives: Run on Chrome with `flutter run -d chrome` for fast web-based iteration.

terminal

flutter create my_app
cd my_app
flutter run

What it does

Scaffolds a starter counter app and launches it on your selected device.

Why you need it

This proves your whole toolchain works end-to-end before you write any code.
