Flutter provides developers with the ultimate freedom to create, architect, and organize their apps. However, this flexibility can also lead to chaotic structures that might hinder testing, maintenance, and extension of the applications. Enter the Flutter Architecture Samples project: a treasure trove of strategies designed to help developers overcome common architectural pitfalls. This guide will take you through how to utilize the samples effectively and put you on the path to creating well-structured Flutter apps.
Why Flutter Architecture Samples?
The Flutter Architecture Samples project showcases various architectural concepts through the implementation of a simple TodoMVC application. It offers developers a reference point to understand how to structure their code and design architecture effectively. The goal is to demonstrate the importance of adopting certain patterns that ultimately enhance testing and maintenance.
Current Samples Overview
- Vanilla Lifting State Up Example – Manages app state using Flutter’s built-in tools.
- InheritedWidget Example – Uses InheritedWidget to share state down the widget hierarchy.
- Change Notifier + Provider Example – Implements ChangeNotifier with the recommended Provider package.
- BLoC Example – Utilizes Sinks and Streams for input and output.
- Redux Example – Incorporates Redux for managing application state.
- MVI Example – Applies Cycle.js concepts to Flutter.
cd sample_directory
flutter runHow to Run the Samples
To run the samples, simply navigate to your chosen sample directory in the terminal and execute the following command:
- For iOS or Android:
cd sample_directory && flutter run - For Web: Make sure you are on Flutter version 1.12.13+hotfix.6 or newer, then use the command:
cd sample_directory && flutter run -d chrome -t lib/main_web.dart
Concepts Explained: An Analogy
Think of organizing your Flutter app’s architecture like building a multi-story house. Each architectural pattern represents a different construction technique:
- Vanilla Lifting State Up is like building a simple framework using standard construction materials. It’s straightforward but may require extra braces.
- BLoC is akin to creating a structure with solid beams; you can steer connections (inputs and outputs) without them being exposed. It keeps everything tidy.
- Redux resembles a modular approach where each room (component) has its identified purpose yet can seamlessly integrate with the overall home design.
- Provider acts like a shared utility room, providing numerous tools for maintenance, signifying a central hub of reference that benefits every room (widget).
Troubleshooting Tips
If you encounter any problems while running the samples, consider the following troubleshooting steps:
- Check Flutter and Dart SDK versions. Ensure they are updated.
- For web projects, be attentive to the sample-specific directories and ensure the proper files exist.
- Revisit the terminal for error logs; they often give clues about what’s wrong.
- If the app doesn’t run correctly, clear the Flutter cache with the command
flutter clean.
