Open source projects drive innovation and collaboration, but creating and maintaining a successful project involves more than just writing code. This talk explores the key steps to launching an open source project, from the initial idea to building a thriving community. We will discuss:
- Designing apps with open source principles in mind
- Setting up open source projects on GitHub
- Managing contributions and community engagement
- Strategies for long-term maintenance of open source projects

A big hurdle that mobile developers have to contend with is developing an app when the backend is not yet ready. Often developers resort to using sample objects and then have to rewrite their code again once the api is set up. But what if we started consuming the api immediately without waiting for the backend to be set up? This is where mocking servers comes in.
In this session we will dive into the details of mocking servers and how it can be leveraged to accelerate development of mobile applications. In addition we will also look into the OpenApi spec formerly known as Swagger which helps us document rest apis in a manner that allows both the generation of the mock server as well as outlining the structure of the api. The OpenApi document can then be used by the backend developers to create an api compliant with the document. Additionally, we will also go through how to mock servers without an OpenApi document for even faster prototyping. By the end of this session, you'll have a solid understanding of how OpenAPI can help you document your APIs and how mock servers can serve as an essential tool for speeding up development and reducing the time-to-market for your products.

SSL Pinning secures the connection by ensuring an app only accepts the server's specific certificate. If the app's stored certificate doesn't match the server's, the connection is rejected, preventing unauthorized access.
When using HTTPS, the server provides a certificate to the app, which may accept any certificate, exposing it to man-in-the-middle (MITM) attacks. Hackers can exploit this to intercept connections and introduce malicious certificates, leading to data breaches and information leaks.
I this session we will Explore the topic of SSL Pinning on Flutter Apps by looking into a walkthrough , advantages and limitations of implementing such.

Topic?Title:
Crafting Reusable Flutter App Templates for Streamlined Development

Description:
Creating and maintaining high-quality apps requires efficient development practices and a unified approach within teams. In this talk, I will explore how reusable app templates can revolutionise how Flutter development teams work, ensuring consistency, ease of onboarding, and rapid project initiation. We'll dive into the problem of starting new projects from scratch and how it can be a tiresome and time-consuming process. To address this, we'll explore the advantages of reusable templates, such as maintaining uniform code standards, facilitating new team member onboarding, and providing a base architecture with a single command.

Solution:
I will introduce BrickHub(https://brickhub.dev/), a platform built on top of Mason Package (https://pub.dev/packages/mason), which provides a collection of tools that allow developers to create, discover, and use reusable templates (bricks). These bricks make it easy to start new projects or enhance existing ones without the hassle of setting up the base structure from scratch. By leveraging BrickHub and Mason, development teams can streamline their workflow and boost productivity.

Key Takeaways:
1. Uniform Code Standards: Learn how reusable templates ensure consistent architecture and coding practices across your team, making it easier to maintain and review code.
2. Efficient Onboarding: Discover how templates can help new team members quickly understand and adopt the architecture and coding standards followed by your organization.
3. Rapid Project Initiation: Understand how reusable templates can save time and effort when starting new projects, allowing developers to focus on building features rather than setting up the base structure.
4. Streamlined Project Setup: Explore the capabilities of BrickHub and Mason, and how they enable the creation, discovery, and utilization of reusable templates called bricks.

Experience Level with the Topic:
I have an expert-level understanding of this topic, with extensive experience in using bricks for various real-world personal and client Flutter projects that serve tens of thousands of users. My notable projects include Calcut and Cupertino Icons Gallery (https://github.com/capps096github/cupertino_icons_gallery), which have benefited significantly from the use of reusable templates. Furthermore, I have also published my own open-source template,(https://github.com/capps096github/Cephas-Bricks/tree/master), which I regularly use to streamline and standardize my Flutter app development process. My practical application of these templates in large-scale, user-centric projects has given me a deep, hands-on understanding of their advantages and best practices.


Have I Given This Talk Before?
This will be the first time I am presenting this specific talk on creating reusable app templates for Flutter teams. However, I have a proven track record of impactful contributions to the developer community. My overall contributions have positively impacted over 10,000 developers, and my answers on StackOverflow have reached approximately 3,000 views. I have delivered 5 event sessions with a combined attendance of 580+ participants and conducted 2 Flutter training sessions for 120+ learners. Additionally, my open-source project has been used by over 8,000 users and has garnered more than 20 GitHub stars. This talk will include fresh insights into the practical use of bricks for real-world Flutter projects, highlighting new techniques and best practices that I have developed and refined through my extensive experience.

Unit test is a way for developers to build robust and scalable software. Golden tests are one of the best tools to quickly spot regression in the code.
Keep in mind that a test is only as good as it replicates the real-life usage of the software.
But default Golden tests don't represent real-life devices.
Let's make them better by changing the window's physical size, and pixel ratio. Let's load images, fonts, and icons. We can even represent notches or an open keyboard!
