Study Notes

Introduction to Flutter

Flutter is an open-source framework for building beautiful, natively compiled, multi-platform applications from a single codebase.
Developed and supported by Google, Flutter uses the Dart programming language and provides a rich set of pre-built widgets and tools for developing mobile applications.

Basic Anatomy of a Flutter App

The main.dart file is the entry point for a Flutter app, containing the main() function that starts the app and runs the initial code.
The MaterialApp widget provides the basic structure for a Flutter app, including the app's theme, navigation, and basic layout.
Widgets are the building blocks of a Flutter app's UI, divided into two types: stateless and stateful.
The Scaffold widget is a common container for other widgets in a Flutter app, providing a basic app layout structure, including the app bar, body, and bottom navigation bar.

Key Features of Flutter

Hot reload: instantly see changes made to the app's code, without needing to rebuild the entire application, reducing development time.

Flutter vs Other Mobile App Development Frameworks

Compared to other frameworks, Flutter offers fast development speed, moderate learning curve, high performance, and growing community support.

Flutter Widgets

Flutter widgets can be divided into two types: stateless and stateful.
Widgets are the basic building blocks of a Flutter app's UI, providing a rich set of pre-built widgets for developing mobile applications.

Navigation in Flutter is typically accomplished using named routes, allowing users to move between different screens or views within the app.

State Management in Flutter

State management is the process of managing the data that drives the app's UI, typically done using the setState() method for simple apps, or by using a state management library like Provider or Bloc for more complex apps.

Packages in Flutter

Flutter packages are pre-built libraries of code that can be used to add functionality to an app, available on the Flutter pub.dev repository.
