How do I install Dart on Windows and make the dart command work in every terminal?

Install the Dart SDK, then add its bin folder to the Windows PATH environment variable and reopen your terminal.

How do I add and display a local image asset in a Flutter app?

Place the image in an assets folder, declare its path under flutter: assets: in pubspec.yaml, then use Image.asset('assets/your_image.png').

What Flutter widget keeps content clear of the status bar, notch, and navigation area?

Use SafeArea to automatically add padding around system UI intrusions.

Build real mobile apps faster—learn Dart, Flutter widgets, layouts, and hot reload in a free online course, with practice to boost your app development skills.

In this free course, learn about

Install Dart SDK on Windows and configure PATH so `dart` works in any terminal
Declare variables and choose `const` vs `final`; understand Dart built-in data types
Use Dart collections: Lists (addAll) and Maps (clear), plus basic CRUD operations
Write loops (for/for-in/while) and use conditionals with equality operator `==`
Define functions with required positional and optional named parameters with defaults
Read console input with null safety and parse/convert String, int, double values safely
Solve FizzBuzz using modulo and correct combined divisibility checks (e.g., %3==0 && %5==0)
Create classes/constructors; use `this` to disambiguate fields; instantiate then set data later
Install Flutter on Windows; run flutter doctor and fix Android toolchain/setup issues
Create a first Flutter app and configure a faster Android emulator/AVD setup
Build UIs with widget tree and Scaffold (AppBar/body), and apply Material colors
Add and display local image assets; generate and place Android/iOS launcher icons correctly
Use hot reload to iterate quickly; lay out with Container, SafeArea, Column and Row alignments

About the free online course

Turn your app ideas into working Android experiences by learning the two tools Flutter developers rely on every day: Dart for clean, reliable logic and Flutter for fast, beautiful UI. This free online course guides you from getting set up on Windows to building your first screens, so you can move from curiosity to confidence without getting stuck on the basics.

You will start by installing and configuring Dart correctly so your environment works smoothly from any terminal. From there, you will build solid programming foundations in a way that immediately supports app development: variables, data types, lists and maps, loops, conditionals, and functions. Along the way you will practice input handling, null safety thinking, and common conversions between strings and numbers—skills you will use constantly when working with forms, APIs, and user-driven apps.

Once the Dart fundamentals are in place, you will shift into Flutter and set up the full toolchain, including the steps needed to resolve typical warnings and run on an emulator. Then you will start assembling interfaces the way Flutter intends: with a widget tree and a Material-style structure that makes your screens feel native and professional. You will gain practical confidence styling an app bar, working with color swatches, and using hot reload for rapid iteration, which dramatically shortens the feedback loop while you build.

The course also strengthens your layout intuition, helping you control spacing and sizing with containers, keep content safe from notches and system bars, and arrange UI elements with columns and rows. You will learn how to bring an interface to life by adding local images correctly and preparing app icons for mobile platforms. By the end, you will have a clear, hands-on understanding of how Dart logic connects to Flutter UI, giving you the momentum to keep building, expand into new widgets, and progress toward more complete apps.
