An introduction to singletons in Flutter: what problems they solve, what other ones they introduce, and what are their alternatives. https://codewithandrea.com/articles/flutter-singletons/
Service classes are the ideal place to store logic that depends on multiple data sources or repositories. Let's explore them by building a shopping cart feature. https://codewithandrea.com/articles/flutter-app-architecture-application-layer/
Asking questions and receiving answers is a two-way street. Here's what to do when you need to ask a technical coding question. https://codewithandrea.com/articles/beginners-guide-coding-questions/
DartPad makes it easy to share your Dart & Flutter samples using GitHub gists, and you can even embed them on your website. Here's how. https://codewithandrea.com/tips/create-dartpad-from-github-gist/
When a test waits for a stream value that is never emitted, it will timeout after 30 seconds (by default). Here's how to make it fail fast with a custom timeout. https://codewithandrea.com/tips/custom-test-timeout-flutter/
The Flutter testing APIs offer some powerful stream matchers and predicates that we can use to verify state changes over time. Let's see how to use them in practice. https://codewithandrea.com/articles/async-tests-streams-flutter/
Since Dart 2.17, you can initialize parameters of the super class with a new shorthand syntax. Here's how. https://codewithandrea.com/tips/dart-2.17-super-initializers/
Since Dart 2.17, we can add members and additional methods when declaring an enum. Here's how. https://codewithandrea.com/tips/enums-with-members-dart-2.17/
Since Dart 2.17, you can pass arguments to the super class with a new shorthand syntax. Here's how. https://codewithandrea.com/tips/dart-2.17-super-arguments/
When writing tests for functions that throw, we should not invoke them directly, but rather pass them as arguments using a tear-off. https://codewithandrea.com/tips/flutter-test-expect-tear-off/
