For a well formatted documentation, please refer here - https://docs.google.com/presentation/d/12OaRgSgVBg0tFRQO4nfQoQL_GqDTxIlnM5on65K3NRQ/edit?usp=sharing

In today's fast-paced digital landscape, individuals place immense value on their time, making any delay in app startup feel like an unwelcome interruption. The expectation for instant gratification is paramount, and any lag in performance can swiftly lead to frustration and a tarnished perception of the app's reliability and efficiency.

In this presentation, we will delve into the pivotal role of app startup time in shaping user experience and retention rates. By exploring the intricate dynamics between startup performance and user expectations, we aim to equip our audience with actionable strategies that can be implemented immediately to enhance overall user satisfaction.

Throughout our discussion, we will address three key themes:

1. Thorough analysis of the main thread to identify and eliminate potential blockages.
2. Strategic deferral of operations away from the critical path of app launch.
3. Optimization techniques for expediting first screen rendering, ensuring a seamless and swift user experience from the outset.
Our exploration will encompass an in-depth examination of various topics, including:

1. Implementation of lazy and asynchronous loading methodologies.
2. Effective caching strategies to optimize data retrieval and processing.
3. Rigorous statistical benchmarking methodologies to ascertain performance improvements.
4. Utilization of Perfetto Trace Analysis to identify and rectify performance bottlenecks.
5. Methodical Trace Analysis techniques for granular performance evaluation.
6. Identification and mitigation of common pitfalls encountered during optimization efforts.

Through this comprehensive exploration, we aim to empower our audience with the knowledge and tools necessary to propel their apps to lighting-speed startup time.

Attendees will leave with actionable insights to ensure their Flutter apps run smoothly and deliver an exceptional user experience. Join me to unlock your app's full potential!

Bringing Google Maps to Flutter: The Power of Plugins

Flutter is a popular cross platform UI toolkit. It allows to develop high quality mobile apps for multiple platforms (Android, iOS, Web, and more) from a single code base. But some app functionality depends on platform specific APIs, a requirement that is seemingly at odds with “one codebase for all platforms”. To bridge this gap, Flutter defined the concept of Plugins to access native apis from cross-platform code.

In this talk I will build a simple Flutter app that displays a map, looks up an address (geo-coding) and plots a route (directions) with help of two existing flutter plugins. Both are cross-platform but under the hood make use of platform-specific apis, combining multiple platform specific solutions into single developer friendly packages.

After showing how to integrate the Google Maps and geocoding packages into my app, I will dissect the basic structure of the two plugins and discuss how a developer might extend them, for example by adding support for a new platform.

Building the future of Android: The power of diverse teams

The android landscape is constantly evolving, and fostering a truly inclusive development environment is key to staying ahead of the curve. This session intends to dive into the power of D&I in building the future of Android.

Flutter Chatter: Let's build a Flutter Chat App Together

I will build a simple chat app from scratch using Flutter and Firebase

Flutter is a popular open-source mobile app development framework. It supports building apps for multiple platforms (including Android, iOS, Linux, and Web) from a single code base. Flutter has gained much respect from the developer community since its introduction in 2017 and is considered particularly suited for smaller teams and MVP (minimum viable product) development.

This talk is meant to inspire developers unfamiliar with Flutter but won't go deep into technical details.

Flutter Multi-Module Clean Architecture

Fortifying API Security in Android Ecosystems: Strategies, Challenges, and Future Trends

In the rapidly evolving Android ecosystem, APIs are crucial in enabling seamless integration and communication between apps and services. However, this vital connectivity introduces a range of security vulnerabilities, especially as the use of APIs continues to grow. With a reported 83% of internet traffic involving APIs and a 40% surge in API-related breaches in 2023, securing these endpoints has never been more critical. This presentation explores the unique API security challenges within Android environments, including authentication, data encryption, and API rate limiting, all essential for protecting sensitive user data and ensuring compliance with privacy regulations.

By examining best practices such as OAuth 2.0 implementation, token-based authentication, Transport Layer Security (TLS), and the use of API gateways, we will demonstrate how these measures can significantly mitigate security risks in Android development. Real-world case studies will showcase how successful organizations have tackled API security, drawing lessons from past breaches to fortify their defenses. We will also delve into the future landscape of API security, discussing how emerging technologies like AI and quantum computing may impact Android APIs and the importance of adopting adaptive security frameworks like Zero Trust Architecture (ZTA) and Runtime Application Self-Protection (RASP). With the complexity of APIs projected to increase by 30% by 2025, this session will provide Android developers with actionable insights to enhance their API security posture, ensuring robust, secure app experiences.

Fragment Shaders In Flutter: A whole new World

Fragment shaders in Flutter expand the horizon of building custom UIs and animations. They go beyond your day-to-day custom painters and render objects to help you create truly custom graphics and special effects for your Flutter apps and games.

With control over every pixel on the screen, you can manipulate your app graphics in a variety of ways to create effects and animations that would otherwise be impossible to do without shaders like real-time image filters seen within Instagram/Snapchat or custom blur, pixellation or even custom navigation transitions for your apps and games.

We'll also explore how Shaders sit at the pinnacle of graphics and how the Flutter engine uses Fragment shaders under the hood for rendering the pixels on the screen. And go into different techniques and tools combined with Custom painting, render objects and more to use Fragment shaders in your Flutter apps and games to create unique digital experiences.
