To show you how it works, we’ve compiled a list of a few awesome workshops created by Flutter GDEs. Give them a try and let us know what you think! 😄

Writing code as a mathematician

Created by Oleksandr Leushchenko

In math, functions always provide the same output for a given input and have no side effects. Devs may also benefit from these universal concepts. In this workshop, we’ll shift imperative logic to declarative and learn some FP patterns in Dart.

Learning Flutter for native iOS developers

Created by Vandad Nahavandipoor

SwiftUI has brought iOS development to a good level, closer to Flutter, but Apple’s decision to have the iOS SDK available only on macOS limits the reach of SwiftUI. In that way Flutter is a lot more flexible. In this workshop I will present Dart and Flutter to those who are familiar with native iOS development and compare the features of Dart and Flutter to those of Swift and SwiftUI. The goal of this workshop is to help you start learning Flutter as a native iOS developer.

Handling errors gracefully

Created by Majid Hajian

Errors can happen anytime in any application. Showing proper messages to your app users will significantly boost their experiences, but how can you do that? In this workshop, we are going beyond try/catch and will handle errors by creating our customer failure class as well as a widget and we will show proper messages based on the received messages.

Implicit animations in Flutter

Created by Paulina Szklarska

Animations are an important part of every application’s look and feel. However, creating them can be sometimes overwhelming. Luckily, Flutter offers a set of widgets that allow to animate properties of the most common widgets in a simple way! In this workshop, you’re going to learn how to modify your existing widgets to convert them into animated widgets.

Add type-safety to Firestore queries with converters

Created by Mais Alheraki

Firestore is a NoSQL database provided by Firebase. It’s one of the most popular choices with Flutter. By default, Firestore document references manipulate a Map<String, dynamic> object. Accessing any field in the Map is not type-safe, we need to make sure a field has the correct type before using its value. In this workshop, we will learn about Firestore converters, and how to use them to make our apps more type-safe.

A beginners guide to Futures

Created by Dane Mackier

Futures are a very commonly used type in Dart and Flutter. Knowing how to use them can speed up your development and help you build more advanced systems. In this workshop we will go over how to use Futures, what to use them for, how to handle their errors and much more.

Implement a LazyIndexedStack

Created by Alex Li

IndexedStack hosts a list of widgets and switches the display between them, but it’ll initialize all widgets at the same time at first. A LazyIndexedStack will initialize each widget when they are actually needed to display, which can save layout costs.

Consistent design with Flutter Theme

Created by Anna Leushchenko

Consistency is a winning strategy for a good application UI. And Flutter developers don’t have to be professional designers to achieve it. As usual, there is a widget for that — Theme! Find more details about effortless consistent Flutter application design in this workshop.

Responsive UIs in Flutter: Creating Fluid User Interfaces

Created by Roman Jaquez

Flutter is a portable language: it can render on Mobile, Desktop, Web — even embedded. But portability goes beyond its cross-platform capabilities. You should strive to make your apps adjust to the multiple screens in which your users will consume your app. In this workshop you’ll learn how to take advantage of the responsive capabilities available in Flutter and make your Flutter apps adapt to the screens in which they render, and create fluid, responsive experience that will delight your users, regardless of the platform, screen size, orientation, etc.

Journey from mobile to Web/Desktop

Created by Aleksandr Denisov

Web/desktop apps are different from Mobile because keyboard and mouse control is different from tapping on the screen. Let’s remake a mobile app into a web/desktop one, and figure out how to properly manage focus and what a hover effect is.

Writing reactive code with Flutter

Created by Pooja Bhaumik

Reactive programming can help build highly reactive and responsive apps that are more data-oriented. You change data in one part of the application, and it should reflect to all the other parts of the application that depend on it and react to the change automatically. We will discover various ways we can use to build such reactive applications in Flutter, including in-built Streams, ValueNotifiers, but also explore community build reactive solutions like Riverpod.

Extension Method

Created by Bhavik Makwana

Extension method allows us to add new functionality to already available libraries. It does not allow us to modify existing code directly but gives us the ability to customize a class in a way that we can use easily.

DartPad Workshops from Flutter GDEs was originally published in Flutter Community on Medium, where people are continuing the conversation by highlighting and responding to this story.

A little over a year ago, the Flutter Community Editorial team decided to pause on accepting new writers.

At the time, we were averaging somewhere between 3–5 new submissions a day with an extensive content backlog of varying length and quality.

As a small three-person team with full-day jobs and other community commitments, the workload became too much. There was not enough time to juggle full-time working jobs and then edit the number of submissions FC was receiving.

Fast forward a year, and things have somewhat stabilized. That’s why we will reopen the writer’s request and submissions for Medium today.

Submission Process

To submit a blog post to Flutter Community, please complete our new submission form with your details.

Given the surge of requests we experienced last year, we will rely on you to keep things moving along. Please review our submission guidelines carefully before sending us your blog posts. Submissions that fail to meet these guidelines will not be accepted.

Please use free grammar and spell-check tools like Grammarly before sending us your blog posts.

Next Steps

After submitting your writer’s request or blog post, we will review your submission and get back to you within a week. For new writers, we will send you an email (to be provided during your submission request) confirming your acceptance.

If you don’t hear back from us within a week, please assume that we kindly passed on your submission.

FAQ

Should I fill out a form if I’m already a writer?

Yes! Please complete a submission via the form even if you are an existing Flutter Community Writer. Keeping submission requests centralized helps a ton when evaluating submissions.

What are the acceptance criteria for submissions?

Our submission guidelines are detailed in this blog post.

How will I know if my blog post is accepted?

If your blog post meets our submission guidelines, a note will be added to your blog post on Medium. For new writers, you will receive a welcome email confirming your acceptance.

Can I cross-post from my website?
