"Power of BuildContext in Flutter"

BuildContext is at the heart of Flutter’s widget tree, yet its true potential often goes untapped. In this talk, we’ll find out what BuildContext really represents, how it connects widgets to their position in the tree, and the powerful capabilities it unlocks. You’ll learn how to access ancestors and inherited widgets, navigate safely, avoid common pitfalls, and optimize performance. We’ll also explore advanced tricks — including using context to measure a widget’s dimensions and dynamically size another widget — giving you the tools to write cleaner, more adaptable Flutter UIs.

"Building AI Agents with self-managing memory"

The challenge with building AI agents is that they do not have a long term persistent memory. We have to manage their memory explicitly. The better way to scale an AI Agentic workflow is to build an AI agent that can self-manage its memory. The concept is very similar to the virtual memory of computer systems. We will also build an AI agent that can write/ edit its own memory.

"Nikhilesh is an entrepreneur, teacher and tech nerd He is an IIT Kharagpur alumnus. He is also a Google Developer Expert in AI and has over 15,000 followers on LinkedIn. Currently, he runs "AI ML etc." - an AI-enabled educational platform for senior IT professionals to learn AI. He is an instructor at LinkedIn Learning as well Recently, he was felicitated by the Chief Minister of Rajasthan for his contribution to education."

"Scaling Server-Driven UI with Stac"

Since the launch of the App Store and Play Store, mobile apps have evolved from static screens to highly dynamic, personalized experiences. Traditionally, the backend drives data while the client controls the UI, but as apps grow, shipping updates and iterating on UIs becomes increasingly complex. What if the server could define the UI itself? What if you could push new screens, features, or fixes without releasing a new app build? Server-Driven UI (SDUI) flips the traditional app architecture: the server generates the UI, and the client simply renders it. This approach enables highly dynamic, personalized apps, faster iteration, and simpler maintenance. In this talk, we’ll explore the principles of SDUI, its benefits for mobile apps, and the practical challenges of building such systems. You’ll also get a hands-on look at Stac, a Flutter SDUI framework that makes it easy to implement server-driven interfaces using Flutter’s declarative UI. Key Takeaways: - What Server-Driven UI is and why it matters - Benefits of SDUI for developers and users - How Stac simplifies building SDUI apps in Flutter - Practical tips and challenges when implementing SDUI -The future of mobile apps with dynamic UIs

"Divyanshu Bhargava is a Co-Founder of Stac. He is a Google Developer Expert in Flutter & Dart and an Organizer of Flutter Abu Dhabi & Dubai. His passion for building apps took him to mobile development. These days, you’ll find him talking about Flutter and the future of tech. He is an open-source enthusiast and an avid tech blogger. When he is not coding, you can find him kayaking, reading, traveling, or thinking about coding."

"Shaping the Impossible: Production-Ready CustomPainter Techniques"

When we start with Flutter, widgets feel like magic. They cover most of our use cases—until one day the design team comes up with something that just doesn’t fit inside the widget box. That’s when CustomPainter enters the picture. In this talk, I’ll share how CustomPainter gives you complete control over the canvas and allows you to create visuals that are simply not possible with standard widgets. I’ll walk you through how I used it in a real production feature—from drawing and manipulating paths to converting an SVG into custom path data. Along the way, we’ll also touch on some simple vector concepts that make life easier when working with shapes and curves. The goal is not just to show cool graphics, but to teach you how to structure your drawing logic, how to keep performance in mind, and how to break down a complex idea into smaller, manageable pieces. By the end, you’ll feel confident about picking up CustomPainter the next time your app’s design demands something unique. I’ll also walk through my experience of implementing CustomPainter in the AMEX Lounge app, where we had to design premium card visuals and dynamic graphics that demanded pixel-perfect accuracy. From breaking down complex drawings into smaller reusable parts, to ensuring smooth performance on high-density screens, you’ll learn what it really takes to use CustomPainter effectively in production. This session is not just about code—it’s about building confidence to pick up CustomPainter when your design vision doesn’t fit inside a widget box. Key Takeaways - Clear understanding of how CustomPainter works and when it makes sense to use it. - Step-by-step process of turning SVG paths into Flutter-friendly drawings. - Easy-to-grasp vector basics that you can apply in your own code. - Practical tips on breaking complex drawings into smaller, testable parts. - Ideas and inspiration to go beyond widgets and build interfaces that stand out.
