Don't let this gap widen
Why this program matters
Without this Dart expert training, your apps risk crashes under load with 40% user loss due to poor performance, as 70% of senior devs report in Flutter stacks.
Imagine x3 latencies on poorly managed streams, memory leaks costing 20k€/year in support, or botched CI/CD deployments delaying launches by 2 months.
Competitors scale via isolates and FFI while you patch basic bugs, losing 25% market share.
Invest 35 hours to avoid these pitfalls: go from good dev to performant architect, boost project ROI x5 starting tomorrow.
Program
Module 1Advanced Dart Patterns: Isolates and Streams for Scalability (Multithreading Exercises, Real Flutter Cases)
Dive into isolates to parallelize intensive tasks, manipulate advanced streams with merge and throttle for smooth flows, complete practical exercises on massive datasets, build a scalable prototype live, test performances in real-time and optimize for mobile, while receiving personalized feedback that boosts your Dart expertise from day one.
Module 2Advanced Async and Packages: Managing Complex Flows (pub.dev Tools, Custom Extensions)
Deepen async/await with generators and custom zones, integrate packages like riverpod for expert state management, create your own extensions and plugins, apply them to a real e-commerce app case, debug live with Dart DevTools, measure impacts on latency, and leave with reusable templates that transform your Dart projects.
Module 3Dart Performance: Profiling and Optimization (Observatory, Benchmarks, FFI)
Use Dart Observatory to profile your code in depth, implement automated benchmarks with package:benchmark, optimize memory and garbage collector, integrate FFI for ultra-fast native C++, test under high-load scenarios, analyze bottlenecks in group, and validate speed gains up to 5x, ready to scale your Dart apps in production.
Module 4Scalable Architectures: WebAssembly and Dart Microservices (Cloud Tools, Deployments)
Compile Dart to WebAssembly for native web performance, structure microservices with Shelf and Angel, deploy on Kubernetes via Dart Frog, simulate extreme loads in practical exercises, integrate monitoring with Prometheus, collaborate in pairs on a complete MVP, and master best practices that make the difference in enterprise environments.
Module 5Expert Project and Best Practices: Advanced Tests, CI/CD (GitHub Actions, 100% Coverage)
Build a capstone project integrating isolates, FFI and streams in a team, implement advanced mock tests with Mockito, configure full CI/CD with GitHub Actions and codecov, conduct live peer code review, deploy to simulated production, receive a personalized audit, and conclude with a concrete portfolio showcasing your expert Dart mastery.

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.
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.
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.
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.
