Learning objectives

  • Deepen asynchronous programming with Futures and async/await
  • Master generics, extensions, and advanced collections
  • Manipulate streams and isolates for multithreaded apps
  • Develop and publish custom Dart packages
  • Implement effective unit and integration tests
  • Optimize performance and memory management in Dart
  • Build a concrete, deployable application project

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Don't let this gap widen

Why this program matters

  • Without intermediate mastery of Dart, your Flutter apps suffer from chronic memory leaks, multiplying crashes by 3 according to Stack Overflow.

  • Async bugs represent 70% of support tickets, costing 20k€/year in debugging per junior developer.

  • Fall behind on a Flutter market growing 60%/year (Google Trends), lose mobile contracts to agile competitors.

  • Performance drops by 40% without isolates, blocking scalability.

  • Invest now or risk professional obsolescence in 6 months.

Program

Module 1Asynchronous Programming and Futures: Manage Long-Running Operations in Dart

Dive into async/await, Futures, and error handling; code simulated API calls with http; chain exercises on timeouts and retry; produce a JSON data fetch script; test in real-time for smooth and reactive apps.

Module 2Advanced Object-Oriented Programming: Classes, Mixins, and Extensions in Dart

Explore generics and mixins for reusability, extensions for fluid APIs; develop a generic cache class with practical exercises; refactor legacy code using these patterns; deliver a production-ready reusable module.

Module 3Streams and Isolates: Reactive and Parallel Programming in Dart

Master StreamController and broadcast streams for data flows, isolates for non-blocking concurrency; simulate a real-time chat via WebSockets; debug with observers; generate a scalable and performant streaming component.

Module 4Testing and Packages: Code Quality and Sharing in Dart

Install the test framework; write mocks and advanced unit tests; structure a pub.dev package with dependencies; publish locally then online; validate via simulated CI/CD; obtain a tested and documented package for future projects.

Module 5Final Project and Optimization: Complete and Performant Dart App

Integrate all concepts into an API + console UI project; optimize memory with profilers; analyze bottlenecks; deploy on Dart Frog; present your functional deliverable; receive expert feedback for immediate enterprise mastery.

Evaluation method

  • Daily quizzes, peer code reviews, final project graded on professional criteria

Learning method

  • Real-world project-based pedagogy, hands-on workshops, immediate feedback

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
