From Network Failures to Offline Success: A Journey of Visible App

Main stage

Scaling an app to thousands of daily active users is a dream come true, but it also comes with its own set of challenges. At Visible, we quickly realized that some of our assumptions about network connectivity and stability were too optimistic. Even a 0.5% failure rate would result in dozens of complaints related to network issues every day.

In this talk, I will share how we overcame this challenge by enabling our app with full offline capability while continuously adding new features for our users. I will dive deep into the technical details, discussing topics like GraphQL caching, background processing, and local storage.

Join me as I share our journey and offer valuable insights for Flutter developers looking to tackle similar challenges.

A safe bridge to the native side

Main stage

Flutter is such an amazing cross-platform framework that it’s easy to forget about its connection with the underlying native platforms. For most of your Flutter journey, you won’t touch even a line of native code... until one day a client requires the use of an obscure SDK that doesn’t have a Flutter implementation, or you want to use that shiny new native feature before it gets official framework support. So, unwillingly, you reach for MethodChannels... but let me stop you right there. In this talk, I will show you a better, type-safe, and more enjoyable way to communicate with the native layer with the help of the pigeon code generation tool.

The 6-Step Flex Layout Algorithm, for Humans

Main stage
RenderFlex errors? No problem. Whether the Flexible in the Flex is going to flex depends on the FlexFit of the Flexible, and if it is going to be flexible then the amount it will flex within the Flex depends on the flex of the Flexible. But if the FlexFit of the Flexible says to ignore the flex, then it's all meaningless because it won't do anything. Clear as mud, right?

This is the talk you've been waiting for since the day you started Flutter. This is the talk that translates all of this jibberish into something a human being can understand. See you there!"

Supercharged UI testing with Patrol

Exhibition stage

Flutter UI integration testing can be really cumbersome, especially in a mobile app that also depends on the native side features. Unfortunately, the Flutter integration test fails when a native permission dialog appears or we’d like to interact with some native platform view.

That’s why we created Patrol - an open-source framework for testing Flutter apps - developed by LeanCode. With Patrol, you can write your UI tests in Dart (like you would with integration_test), but you are enabled to test interactions with the native side - tap on native views, browse WebViews, and even interact with some other app on the device.

In this talk, we’ll take a look at problems with integration testing, how Patrol solves them, and how you can use Patrol to supercharge your testing game.

Supercharged Design System: Enhancing Widget Cataloging, Testing, and Collaboration with designers

Exhibition stage

Creating beautiful UI has never been easier with Flutter. However, managing and organizing widgets effectively can pose challenges for developers, particularly when it comes to organizing them, testing them in all their different use cases, and maintaining design-code consistency. This is where Widgetbook comes in.

In this talk, we will see how we can use the open-source Flutter package Widgetbook to build our own design system/widget library and test our widgets across different devices, themes, and languages. We will connect our Figma designs directly to our Flutter widgets and set up a CI/CD integration with Widgetbook that simplifies the review process with designers. Thereby, we will learn how to keep design and code sync.

Key takeaways:

- How to build your own design system / widget library

- How to quickly test your widgets on different device sizes, themes, languages, etc.

- How to collaborate effectively with designers to keep design and code sync

Behavior Driven Development with Flutter

Main stage

If there is something that projects tend to ignore are TESTS. With the same mindset of Test Driven Development (TDD) we get Behavior Driven Development, but instead of writing tests we use a simple text definition for all tests with a language called Gherkin. With this talk you will learn the fundamentals of BDD, the reasoning behind them and we'll see how to implement it with Flutter!

What hit tests really are

Exhibition stage

In this talk we will answer some questions such as:

What are hit tests? How do they work? What do we use them for? Why do they work differently on the web and on mobile devices? Why are there native events, raw gesture detectors, gesture detectors or gesture arenas 🤯‽.

And finally, why they matter and why we need to think about gestures when developing applications.

Anna Leushchenko
Basic and advanced networking in Dart and Flutter (Location: Devoteam)

Most applications, be it mobile, web, or desktop, depend on some kind of backend. Thus, an API layer is an integral part of application implementation. This is a hands-on workshop, where Anna will present tools and approaches that facilitate an effective API layer implementation in Flutter and Dart applications.

We will apply this knowledge together to create a Flutter application that displays data obtained from a hosted REST API. You will walk away with knowledge about code generation in Dart and its application examples, and learn a  few cool hacks on how to turn its principles to your advantage.

Anna is a Ukrainian Flutter & Dart GDE and a Senior Staff Mobile Engineer Senior at Tide.

Mike Rydstrom
Theming from basics to advanced, the hard and the easy way (Location: NoA Consulting)

In this workshop we go from basic light/dark Material 3 theme setup and defining the color system’s ColorScheme, using different ways to seed generate it, while respecting desired brand colors and increasing colorfulness. To, showing how to seed generate mono hue-based themes, that have only one brand color but are still color expressive.

We will explore best practices for customizing ThemeData, its TextTheme and text styles, how to use using semantic colors and customizing component themes in Material 3. How can we modify Material 3 defaults to make it less opinionated and more platform agnostic?

Next, we make the same design again, but this time by using the Themes Playground to visually configure the desired theme and reproduce what we first made manually with vanilla ThemeData. We will copy paste the FlexColorScheme API config code from the Themes Playground and let FCS produce the same ThemeData for us. We also go a step further and look at advanced options in the Playground, like platform adaptive theming.

Flutter Animations: From Beginner to Advanced (Location: NoA Consulting)

User interfaces without animations are like food without salt, just tasteless. In this workshop, you will learn how to add animations with various complexity to your Flutter UIs.

We will start by covering the most basic and subtle animations created with built-in widgets, and make our way up to complex animated user interactions with advanced and customized widgets.

Along the way, you will learn best practices, performance optimization, and tips on how to make your development experience and flow smoother. Lastly, just like too much salt can ruin a meal, you don’t want to overcrowd or overcomplicate your UI with too much animations, so we will end up our workshop with some important user experience tips to make sure your app has the most optimal impact on your users.
