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…

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…

An overview of the Observer design pattern and its implementation in Dart and Flutter — In the last article, I have 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. …

An overview of the Mediator design pattern and its implementation in Dart and Flutter — Previously in the series, I have analysed a behavioural design pattern that separates algorithms from the objects they operate on — Visitor. This time I would like to represent once another behavioural design pattern that lets you reduce dependencies between a set of interacting objects by decoupling the interaction logic…

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, build products and their details page. All the other implementation details were left up to me…

An overview of the Visitor design pattern and its implementation in Dart and Flutter — In the last article, I have analysed a behavioural design pattern that enables loose coupling between the sender of a request and its receiver — Chain of Responsibility. …

An overview of the Chain of Responsibility design pattern and its implementation in Dart and Flutter — Previously in the series, I have analysed a structural design pattern that introduced a concept of a “shared object” which could be used in multiple contexts simultaneously, hence reducing the memory usage of your code — Flyweight. …

An overview of the Flyweight design pattern and its implementation in Dart and Flutter — In the last article, I have analysed a creational design pattern that divides the construction of a complex object into several separate steps — Builder. …

How to convert design into code using Dart + Flutter. — When I started my journey in the Flutter world, I have learned the basic UI concepts just enough to build a simple application. State management, code structure, architecture, appliance of OOP design patterns — these topics are more interesting to me, so I have dived deeper into them. …
