Rick and Morty Info

A simple app to demonstrate Clean Architecture with GraphQL and flutter_bloc

Motivation

In Martin Fowler's words,

“Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” (Refactoring: Improving the Design of Existing Code, 1999, p. 22)

With this idea in mind, I wanted to demonstrate how we can make a simple app in production grade (and I hope I made my case).

"Production level" implementations

• CI/CD with GitHub Actions
• Githooks to ensure clean commit and push
  • Pre commit formats with flutter format
  • Pre push checks the code with flutter analyze and flutter test
• Linting style with Effective Dart
• Test coverage with Codecov
• Dependency Injection with injectable and get_it
• Testing with mockito and bloc_test

Installation

• Check if you are in the beta channel of flutter SDK and the version v2.0.1 or higher. Instruction to change flutter channel.
• Clone the repo

  git clone https://github.com/excogitatr/rick-and-morty-info.git

• And then we can use the normal build and run procedure

  flutter pub get
  flutter run

• Some files like *.freezed.dart, *.g.dart, *.iconfig.dart are auto generated. If there is any issue from these files just run this command to regenerate them.

  flutter pub run build_runner watch --delete-conflicting-outputs
