"Code less, deliver more" virtual talk at the Flutteristas conference

Lots of everyday programmer tasks consist of creating boilerplate code. It’s not only boring, time-consuming, and error-prone, but it also requires efforts to maintain it later. With code generation, you can create only the essential code and leave all the routine to the computer.
We’ll see how code generation works in Flutter and what typical tasks it can facilitate in mobile apps development.

"Flutter: What? Why? How? Where?" online talk at Women in Tech Global Conference

What is common between BMW, Alibaba Group, Google, Toyota, Square, and eBay? - They all have products created with Flutter. In fact, there are already over 200K applications on Google Play alone created with this beautiful, fast, productive, open, and portable framework.
We’ll talk about what Flutter is, why you should consider it as a technology choice in your company (or why not), and how you can start incorporating it into your projects.

"Yet another localization approach in Flutter" online talk at Flutter Global Summit

When it comes to localizing Flutter applications, there is already quite a number of approaches. Some offer strongly typed message keys, while others leave you guessing whether a message exists and with no refactoring support. Some use custom commands for generating code and don't offer a file system watching, while others imply only manual work. They differ by supported file formats, pluralization support, a mechanism for locales switching, etc.
In this session, I will share what I am looking for when it comes to localizing Flutter applications (spoiler alert: code generation with build_runner is one of the key requirements), explain the solution that combines pros and avoids cons of existing approaches, and implement it in a multi-language Flutter app live.

"Trash talk: WHENs and HOWs of Dart VM’s GC" virtual talk at Flutter Vikings conference

In the dark deeps of Dart VM, where trees are boughy, tracks are twisted, and the space is limited, there lives a bright hero, who always welcomes new visitors, helps them find their way and stay connected to the roots, respects their age; who cares about the environment and diligently collects and recycles the garbage, freeing up space for new visitors.

Garbage Collector rarely gets the love and attention it deserves. Even though every Flutter developer has it as their friend, only few know it close enough, what it is like, and how it behaves.

I am determined to fix this injustice by spreading the word about all the good things Dart VM’s Garbage Collector does: we’ll look at how Dart objects are allocated, managed, and moved around, and when and how they get collected.

"Fun with code generation" in-person talk at Flutter Vikings conference

Data models, JSON serialization, API requests, navigation, localization, dependency injection, tests, assets management are all typical tasks to be solved when developing a mature Flutter application. Quite often, it involves creating boilerplate code. It’s not only boring, time-consuming, and error-prone, but it also requires later maintenance. Code generation with build_runner makes it more fun, it allows creating only the essential code and leaving all the routine to the computer.
We’ll create a Flutter mobile application and apply the build_runner code generation technique to as many tasks as the time allows. Hopefully, it’ll be fun.

"Building Flutter apps in Lego style" virtual talk at Flutter Vikings conference

What’s the coolest thing about Lego? It’s the countless amount of combinations of little pieces that are put together through a primitive connection interface. This simplicity and versatility hold great power. Once you learn how to combine the bricks, you can unleash your creativity and build anything imaginable.

The same composition concept can be applied to building Flutter apps. Individual building blocks, containing UI, state management solution, business logic, dependency injection, navigation, localization, and configuration points, are put together through common interfaces just as Lego bricks. They can be easily plugged in and out and reused across products.

Join us to learn how to build Flutter apps in Lego style!

"Private Dart and Flutter packages" virtual talk at Flutter Forward

It is hard to imagine a mature Flutter project written in a single package. Sooner or later, product scale forces to split the project into multiple packages. There are multiple ways of referencing packages in pubspec.yaml. The most common of which is to use hosted packages from pub.dev. However, it is not always possible to open source the team’s work, hence there is a need for private packages. In this video, we show how private packages may be referenced and what is the most convenient way of working when you need to keep packages secret and safe.

"Mobile apps distribution with Firebase" talk at Flutter Firebase Festival

Having a well-defined release strategy is important for the success of any commercial mobile product. A good strategy should include some form of distributing release-candidate builds to the testers and internal users before uploading them to app stores for general availability. This allows catching problems earlier which dramatically improves the quality of the final product.

Firebase Distribution is a great way to solve this task: it's easy to use, secure, and reliable. First, we’ll look into using Firebase Distribution via web interface to create testing groups and distribution rings, and to share builds internally.

Automating build distribution is not an easy process, but it’s a time and effort-saver in the long run. That’s why we'll demonstrate how to use the Firebase CLI tool and Fastlane to automate this process on CI.

Is your JSON deserialization implementation efficient?

I think we all agree that JSON deserialization is one of the most common tasks we as developers of Dart and Flutter applications, have to perform regularly, which means that implementation efficiency in this area has a significant impact on the overall speed and ease of the development. Yet over and over I see a few pretty common scenarios.

Some folks prefer to do JSON deserialization manually, which is more time-consuming and error-prone than using code generation. And even if they do use code generation, they’d have data models with JSON deserialization logic, corresponding domain models with similar structure, and mappers that copy data back and forth between data and domain models, maybe with slight modifications.

Clearly, such an approach has a big benefit: if there's a change in the data structure received from the backend, the required application change is minimal and is contained in the deserialization logic, so that the domain model structure remains unchanged and thus no further updates are required in the business logic layer and above. This is a very important benefit, and in this session, I’ll show you how to achieve the same result with less code.

Your ultimate guide to code generation productivity for Dart and Flutter

Creating Dart and Flutter applications often includes typical tasks, such as implementing JSON deserialization, consuming backend APIs, creating a dependency inversion mechanism, implementing navigation and localization, managing assets, writing tests, and more. These tasks require writing repetitive code, which is time-consuming, error-prone, and tedious. Fortunately, we can get a significant development productivity boost by letting build_runner generate all the boilerplate. But once the project grows, extensive usage of code generation brings additional challenges, such as slower generation execution, frequent merge conflicts, analyzer performance downgrade, and others.

In this session, we will discuss how build_runner and different code-generating packages can facilitate many typical application development tasks, and also talk through a dozen practical tips for efficiently maintaining Dart and Flutter projects that extensively use code generation. I will not only show how to speed up the generation process, but also how to minimize chances for merge conflicts and improve overall developers’ experience.

Even if you are familiar with code generation topic, you will certainly get valuable takeaways from this session!

Build for users, not platforms

To be successful, modern businesses are required to meet their potential clients right where they are. Users expect applications to be available on their phones, tablets, and desktops, providing a familiar experience across platforms.

However, each operating system has its own design language recommendations. Blindly following these guidelines when developing an application would lead to a generic soulless product lacking distinction. At the same time, extremely unusual and unique designs may misalign with users’ expectations and confuse them.

While maintaining consistency with platform conventions is essential, it’s equally crucial to implement a strong brand that would stand out among competitors. In this session, we’ll dive into the topic of prioritizing user experience over platform-specific design, explore how focusing on users rather than platforms can support the brand identity and improve user satisfaction, and give recommendations on how to implement this in practice.
