Dominik Roszkowski - Native Platform Views for Mobile and Beyond - Flutter Heroes 2023. In this talk we’ll review how to use Platform Views on Android and iOS. What are the most surprising considerations when working with them? What if some native library does not support Flutter and you need to display its UI in the app? We’ll look into showing native views on desktop platforms and see what is still missing in this area.

Teresa Wu - The Ultimate Cookbook of Flutter Testing - Flutter Heroes 2023. In this talk, I am going to walk you through every layer of testing, starting from Unit testing to integration testing, and slowly move up to E2E tests, giving demo of each piece while looking at testing as an independent component, and how we should design our project with testing in mind. The fundamental concept is that if your project can be tested, then your code is clean. A few other tools I will be covering in this talk include: the concept of BDD, API tests, Contract tests and test automation. Teresa Wu, VP of Software Engineering and GDE Flutter/ Dart, JP Morgan Chase

Akanksha Singh - Power Up your Flutter Apps with Voice - Flutter Heroes 2023. With the accelerated adoption of digital technologies due to COVID-19, conversational AI solutions including chatbots, virtual agents, and voice assistants have also become even more popular. “Hey, Google!”, “Ok, Google” are probably some of the first words kids of today’s generation are learning. A growing preference for voice interaction with virtual assistants is booming as voice interface provides convenience to millions by saving time and the cognitive burden that goes into typing a query they want to be answered or a task they want to be done. In this talk, I will cover use cases of conversational AI and discuss different methods and packages one can use to add this functionality to their flutter apps which will not only improve the user experience but also make the apps more accessible.
