In this episode, my guest is Waleed Arshad and we talk about state management in Flutter.

Waleed is Pakistan’s first Google Developer Expert in Flutter and GDE in Dart. He’s the author of the book “Managing State in Flutter Pragmatically: Discover how to adopt the best state management approach for scaling your Flutter app“.

We talked about why state management is such a hot topic amongst Flutter developers and we talked about different state management options: setState, InheritedWidget, Provider, Riverpod, Bloc, Cubit, MobX, and more. We also discussed whether choosing this or that state management library is even so important as we previously thought if we layer, design, architect our application correctly.

At the time of recording this episode, I couldn’t read the book yet, it wasn’t public yet, but since we recorded I bought the book and read most of it, and I can only recommend it.

In this episode, I talked to Maksim Lin. Maks is a Google Developer Expert in Flutter, and he’s an Android and Flutter Developer. He’s a passionate contributor, user, and supporter of open-source software. He’s also a regular speaker at technical conferences and local developer group meetups.

Today, we are going to talk about isolates, isolate groups, the actor model, improvements and limitations of isolates, concurrency, and we will even talk a little bit about "the soul of Erlang and Elixir".

It’s Maks’s second episode on the Flutter 101 podcast. In Episode 21, Maks and I were talking about WebAssembly, Dart, and his Dart-WASM project. In both episodes, I had these "wow" moments, as I realized how important WebAssembly will become in the coming years in software development, I had these "wow" moments, as I realized the potential behind the improvements to the Isolates, how the isolates make Dart such a powerful language... so I really hope that you will be just as excited when you are listening to this episode as I was when we recorded it.

Today, I wanted to share with you a very interesting open-source project, Widgetbook. My guest is Lucas Josefiak and he is the co-founder of Widgetbook. Widgetbook is "an open-source tool for organizing widgets in Flutter. It helps developers cataloging their widgets, testing them quickly on multiple devices and themes, and sharing them easily with designers and clients".

It’s a problem that I probably faced at every team and project I worked on, and on some teams, we even tried to implement some sort of secondary application just to showcase, document, and test our reusable components and pages, so I was very glad that Lucas decided to join me for an episode.

Widgetbook is inspired by flutterbook, and Storybook, maybe that sounds familiar to some of you.

I’d like to apologize for the audio quality from my mic, I was not recording from home and I didn’t have my regular microphone with me, but I hope the quality is still good enough and I hope that you will enjoy this episode.

In this episode, I talked to David DeRemer, the Founder and President of Very Good Ventures. VGV, Very Good Ventures, is a global Flutter development consultancy. Their work and apps were featured on multiple global Flutter events, for example, they built the first major Flutter desktop app, the Flutter slides app for Flutter Live 18, as well as the Google I/O photo booth app, the multiplatform New York Times KENKEN game, and the Hamilton app.

I talked to David about Very Good Ventures, why they went all-in on Flutter, how the Flutter ecosystem has grown since the company was founded, we’ll talk about open source development, building things reliably and consistently, the importance of testing, and David also shared with us the approach they took to building a great team.
