Learn Flutter and Dart: Complete App Development Projects

Get a beginner-friendly overview of the Dart language, focusing on variables, lists and maps, control flow, functions, and objects and classes, with hands-on code demos for Flutter.

Explore how variables act as placeholders for data, covering declaration and initialization. Understand types such as string, integer, double, boolean, and concepts like final and dynamic.

Demonstrate variables in Flutter and Dart by building a game character, declaring string, int, double, and bool types, using dynamic and final, and defining a constant with console prints.

Explore variable operators in Dart, covering arithmetic, assignment, equality, the full ternary, and logical operators, with both binary and unary forms and pre- and post-increment examples.

Explore the five kinds of variable operators: arithmetic, assignment, comparison, ternary, and logical negation, with practical on-screen demos and printouts.

Learn how to create lists that hold multiple values, access and set elements by zero-based index, and apply common list operations like length, insert, contains, first, last, and indexOf.

Explore lists in Dart with a video game character inventory demo, showing how to create a string list, access items by index, range, set, and for each operations.

Explore maps, or dictionaries, as key‑value pair collections replacing lists. Learn to initialize with curly braces, set and retrieve by key, noting keys are unique and order does not matter.

Learn how functions work in programming by defining a named block with parameters and a return type, calling it to perform tasks like summing two numbers.

Discover the basics of control flow in Dart, and learn how true/false tests drive code paths with if and switch statements, including else, else if, and default cases.

Explore control flow in Dart by building a game character example that uses if-else-if and switch statements to track current, halfway, and end positions, with practical tests and messages.

Learn loops in Dart, focusing on while and for loops, and how to control flow, repeat code, and avoid infinite loops with break and continue.

Master while and for loops in Dart with practical demos, using break and continue, to move a game character toward an end point and build a string with inventory items.

Master how classes act as blueprints and how objects hold state through fields and behavior through methods, then instantiate them with constructors to create usable instances.

Create a generic game object class and instantiate it to demonstrate properties, a constructor, and a move method that updates x and y positions, illustrating object state in action.

Explore how inheritance in flutter and dart uses a superclass and subclass, with extends and overriding via super, to create scalable, reusable game object code.

Demonstrates inheritance by extending the game object to create a game character with x and y positions, name, health, and max health, using a super constructor and an overridden move.

Master Dart basics—variables, lists, maps, functions, control flow, objects and classes, and inheritance—and apply practical examples to start building apps with Dart and Flutter.

Explore Flutter widgets, learn what widgets are, differentiate between layout and interactive elements, and start building with core widgets, padding, rows, columns, and basic containers.

Explore how to build flexible grid layouts in Flutter using columns and rows, manage alignment with main axis alignment, and create reusable colored circle widgets for a responsive UI.

Explore Flutter text widgets to display static or dynamic text and style them with text style, color, size, weight, shadows, and decorations while learning practical usage in a Flutter app.

Learn to add and customize Flutter's material buttons, using onPressed, text or icon children, color, splash, elevation, and setState updates.

Learn to build and customize Flutter text fields in Dart, including placeholders, alignment, capitalization, and keyboard types, and manage input with onChanged, onSubmitted, and a text editing controller.

Build a simple calculator interface in Flutter with a text display and four button rows. Modularize with createButton and createRow to streamline the interface.

Explore building a responsive Flutter UI using expanded widgets to split the screen, apply padding, and align elements to bottom-right for balanced, full-width controls.

Refine the UI by styling text with larger bold fonts, light gray backgrounds, and outlined buttons, then cover passing user inputs and displaying the correct output.

Learn to handle user input in a Flutter app by processing button presses, building a number string, and displaying the correct outputs while managing clear and equals.

Implement arithmetic functionality in the calculator by handling input, updating a double result, applying plus, minus, multiply, and divide, and displaying the computed value as a string.

This bonus explains adding a shouldCalculate flag to the calculator to accumulate all prior operations, enabling 8 plus 8 plus 8 plus 8 to compute correctly while preserving results.

Learn to build a Flutter image guessing app with left-right swipes, a snapping carousel, and a reveal button to show vehicle names using custom widgets and drag gestures.

Learn to build the main user interface for an image guesser app in Flutter, including scaffolding a blank page, a styled outline button, and dynamic text for the current vehicle.

Import images into your Flutter and Dart project by creating an assets/images folder, listing each asset in pubspec.yaml, and displaying them with Image.asset in a scrollable gallery.

Develop a custom image card widget that loads images by name, adds a bordered rounded container, and clips borders, then prepare for a horizontal card carousel with swipe gestures.

Build a stack of image cards by adding a build card and build cards functions, calculate scroll percent, and apply fractional translation to position each card.

Attach a gesture detector to a stack of cards, implement horizontal drag start, update, and end to drive a snapping animation and load the next card in Flutter.

Implement a snapping swipe that focuses on one card using an animation controller, a ticker provider, and a listener to drive finish scroll progress.

Implement show answer functionality by linking images to vehicle names, displaying the correct answer on button press, and hiding it on horizontal drag to the next image.
