Learn Flutter

Create a Flutter project, understand its folders and main(), run it on a device, and use hot reload and hot restart.

Build UIs by composing immutable widgets, write StatelessWidgets, and understand build methods and BuildContext.

Structure screens with MaterialApp and Scaffold, and style the app consistently with ThemeData, ColorScheme and text themes.

Arrange widgets with Row, Column, Stack, Container, Padding, SizedBox and alignment properties.

Show scrollable content with SingleChildScrollView, ListView, ListView.builder, separators and GridView.

Declare assets in pubspec.yaml, show local and network images, and use icons and resolution-aware variants.

Understand Flutter's rule that constraints go down, sizes go up and parents set position, and fix overflow and unbounded errors.

Adapt layouts to screen size with MediaQuery, LayoutBuilder and breakpoints, and respect safe areas, orientation and platform conventions.

Compose scrollable areas from slivers with CustomScrollView, SliverAppBar, SliverList and SliverGrid.

Keep mutable UI state in a State object, update it with setState, and use initState and dispose.

Handle taps with buttons and GestureDetector, read text with TextField and TextEditingController, and use switches and checkboxes.

Group fields in a Form with a GlobalKey, validate with validator functions, and submit safely.

Lift state up, share it with InheritedWidget, model it with ChangeNotifier, and use provider or Riverpod for app-wide state.

Learn how widgets map to elements, when State is kept or recreated, and how ValueKey, ObjectKey, UniqueKey and GlobalKey change that.

Move between screens with Navigator push and pop, pass arguments and results, and use go_router for URL-based routing and deep links.

Show loading, data and error states for asynchronous work with FutureBuilder and StreamBuilder, without refetching on every build.

Call REST APIs with package:http, decode JSON into typed model classes, and handle status codes and errors.

Animate with implicit widgets like AnimatedContainer, build explicit animations with AnimationController and Tween, and use Hero transitions.

Test logic with unit tests, UI with widget tests using WidgetTester and finders, and full flows with integration_test.

Structure apps into UI, view models, repositories and services, inject dependencies, and keep data flowing one way.

Understand widgets, elements and render objects, the build-layout-paint-composite pipeline, and how Impeller draws frames.

Find and fix jank with profile mode and DevTools, reduce rebuilds, use const and RepaintBoundary, and avoid expensive effects.

Call native Android and iOS code with MethodChannel and EventChannel, generate type-safe bindings with Pigeon, and call C with dart:ffi.

Draw charts, gauges and custom shapes with CustomPaint and CustomPainter, repaint efficiently, and animate drawings.
