Training for development teams

Flutter training for companies: get your team building cross-platform apps

A hands-on course that teaches your team to build and maintain iOS and Android apps from a single codebase. The curriculum is tailored to what the group already knows and the app it’s about to build.

When a team needs to learn Flutter

The course makes sense in situations like these:

  • The company maintains two separate apps, one for iOS and one for Android, and wants to consolidate them.

  • The team comes from web development or another language and is about to start its first Flutter app.

  • You already have a Flutter app, but state management and code structure have become hard to maintain.

  • An outside vendor delivered the app and now your in-house team has to take it over.

What this course is, and what it isn’t

It’s training for your team, not an app development service. We haven’t published a case study of a Flutter app we built ourselves yet, which is why this page is about training rather than delivered projects. If you need someone to build the app, the first decision is whether it should be native, a PWA or a responsive web app; our mobile apps page walks through that choice.

Flutter course topics

This is the core path. The order and depth of each topic are adjusted to your team.

  1. 1

    Dart for the team

    Types, null safety, classes, collections and async programming with Future and Stream: what you need to read and write Flutter code comfortably.

  2. 2

    Widgets and UI

    How screens are built from widgets, layouts that adapt to different sizes, theming and reusable components.

  3. 3

    Navigation and structure

    Routing, passing data between screens and a layered project structure the team can maintain.

  4. 4

    State management

    When setState is enough and when a solution like Provider, Riverpod or Bloc pays off, with the trade-offs of each.

  5. 5

    Data and services

    Consuming APIs, handling errors, local storage and user authentication.

  6. 6

    Testing

    Unit, widget and integration tests so the team can change the app without fear of breaking it.

  7. 7

    Release

    Building for iOS and Android, signing, versioning and the App Store and Google Play review process.

Who this course is for

People who already code and are about to work with Flutter.

  • Web developers and other programmers

    They know how to code but have never built an app with Flutter.

  • Native mobile teams

    They work in Kotlin or Swift and are weighing a move to a single codebase.

  • Teams already using Flutter

    They want to clean up the structure, state management and testing of an existing app.

  • Tech leads

    They need solid judgment on whether Flutter is the right tool before committing the team.

    We've worked with Crece Virtual on several web design projects for our Barranquilla operation. Their team demonstrated a solid command of both WordPress and React, adapting to the specific needs of each project based on our technical and functional requirements. What we value most is the quality of the codebase they deliver. Each project has a clean and well-organized structure, which has greatly facilitated updates and the addition of new features when needed. The technical documentation they provide is clear and useful for our internal team. Communication throughout the entire process was smooth and professional.

    Working with Crece Virtual transformed how we acquire clients. From the outset, they understood our business and guided us through everything: digital strategy, website architecture, and domain selection. The WordPress site, with a custom theme and widgets created in Elementor, turned out exactly as we needed: fast, clear, and designed to make requesting quotes effortless. Thanks to technical SEO, link building, and Google Ads campaigns in Medellín, our quote requests increased several times over, stabilizing at nearly 500% higher than at the beginning. The automation that sends leads from WhatsApp to Google Sheets, complete with all the data and UTM parameters, allows us to better measure sales and repeat purchases. Furthermore, their hosting, domain, and Google Workspace services have been reliable, and whenever we need support, they're always there with quick and clear answers.

    We have been working with Crece Virtual for several months now, and it has been a great experience. They built our website in Next.js, and it turned out super fast and professional. The best part is that they didn't leave us on our own after delivery: every month they make updates and improvements, and when we need something urgently, they always respond very quickly. Their support has been impeccable. In addition to the website, they manage our Google Ads campaigns and SEO. Honestly, everything has worked very well. The campaigns bring in good leads and have us well positioned on Google and Bing. They are very professional but also very approachable, always explaining everything clearly. I recommend them without hesitation.

The design is elegant, professional, and conveys the seriousness we needed as an environmental project. Navigation is intuitive, and our clients can easily find the information they're looking for. Regarding SEO and ads, we now appear in the top Google results for the searches that matter to us. The team was incredibly professional, met every deadline, and was always available to answer questions. It's clear they know what they're doing.

    Recommended, they designed the school's website, provided technology training (software) to the entire staff, and were extremely responsive and fast.

Flutter course FAQ

Who is the course for?

People who already code, in any language, and are going to work with Flutter. It isn’t a learn-to-code course: anyone on the team who has never programmed should start somewhere else first.

Does the course cover architecture?

Yes. Beyond widgets and screens, we cover how to structure the project in layers, how to manage state and how to test the app, which is what matters most once it grows and more than one person maintains it.

Can it be tailored to our team and our app?

Yes. We assess the group’s level and, if you already have an app or a design, the exercises are built on that project or a similar one.

How long is it, and how is it delivered?

Length, schedule and format are set in the proposal, based on the topics your team needs. We work remotely from Colombia on UTC−5, which overlaps with US business hours.

Do you also build Flutter apps?

This page is about training. We haven’t published a case study of a Flutter app we built yet, so we won’t present it as proven experience. If you need the app itself, let’s start by deciding whether it should be native, a PWA or a web app.

Train your team in Flutter

Tell us how many people are on the team, what they use today and which app they’ll build or maintain. We’ll use that to put the curriculum together.

If you already have a Flutter app, tell us which part is hardest to maintain.
