Overview of Firebase Remote Config and how to use it to enable real-time features in your Flutter application

Real-time updates, feature flagging and A/B testing - what if I told you that you could enable these powerful features in your Flutter application with minimal development effort and without any costs? In this article, I will cover multiple real-world use cases where Firebase Remote Config could help you while building Flutter apps.

Enabling supply chain security features for Dart and Flutter projects on GitHub

On October 6, 2022, GitHub announced the availability of supply chain security features for the Dart developer ecosystem. This post will review the available options and how to enable these features for your projects.

Creating a fun Flutter form validation animation in 15 minutes or less

In this short tutorial, we will create a NOPE form validation animation in Flutter. All you need is a basic understanding of Flutter and Dart. Let's get started!

Dart type system goes: never say never…

First of all, the title of this article could seem like just another clickbait but let me explain. Sure, there is a chance that you have used this type, but for the sake of a pun (and I REALLY enjoy them), I had to do it - oh well, here we are now. The thing is, the type I am going to talk about in this article is actually called Never.

An extensive checklist to kick-off a new Flutter project

Creating a new Flutter project is a blessing — fresh codebase, no legacy code (yet), null-safety, most recent versions of your favourite packages and so forth. But at the same time, you should make critical decisions at the beginning of the project that would lay the foundation for the future, such as tooling, packages, file structure, state management solution, testing plan. Otherwise, the project would eventually turn into just another bowl of spaghetti and meatballs. To avoid this, I have prepared a list of, in my opinion, the most important elements of the project that should be decided early on.

Some insights on how to implement a production-quality app using Dart + Flutter

Recently, I received a task to build a shopping app prototype using Dart + Flutter. The main requirements were to use the real-world e-commerce API of free choice, implement lazy products' loading and caching, and build products and their details page. All the other implementation details were left up to me, hence I had to decide on the app architecture, state management solution, third-party packages, etc. So in this article, I will reflect on my choices, challenges and other details while implementing a production-quality prototype.

An overview of the Observer design pattern and its implementation in Dart and Flutter

In the last article, I analysed a behavioural design pattern that reduces dependencies between a set of interacting objects by decoupling the interaction logic from the objects and moving it to a dedicated controller - Mediator. In this article, I would like to analyse and implement another behavioural design pattern that lets you define a publish-subscribe mechanism to notify multiple objects about any events that happen to the object they're subscribed to - it is Observer.

An overview of the Mediator design pattern and its implementation in Dart and Flutter

Previously in the series, I analysed a behavioural design pattern that separates algorithms from the objects they operate on - Visitor. This time I would like to represent one another behavioural design pattern that lets you reduce dependencies between a set of interacting objects by decoupling the interaction logic from the objects and moving it to a dedicated controller - it is the Mediator.

An overview of the Visitor design pattern and its implementation in Dart and Flutter

In the last article, I analysed a behavioural design pattern that enables loose coupling between the sender of a request and its receiver - the Chain of Responsibility. In this article, I would like to analyse and implement another behavioural design pattern that lets you separate algorithms from the objects on which they operate - it is Visitor.
