Flutter APP development

MY EE — Link

My EE app offers an intuitive dashboard to manage all EE services, including payments, E-commerce, and configuration of EE wifi devices. Testing a new communication module written in Dart with the intention of ensuring compatibility with the Flutter module was the first step in the project, and I got involved very early on stage. I assisted in setting up a demo application to test the communication module's capabilities for all real-world use cases and applications, as well as in organising the application's architecture in a clear and organised manner using the BLoc workflow and also participated in helping other engineers to learn Flutter. After the proof of concept was completed and the main application's design and development got underway, I was actively engaged to create reusable, responsive Flutter widgets for both the Android and iOS platforms. During my first year, my primary responsibilities included setting up Wi-Fi devices, onboarding development users, and resolving any compatibility issues that may have arisen. One of the compatibility issues were that The 'Scan to Connect' functionality stopped working on Android 10 due to security restrictions that prevented third-party apps from programmatically connecting to WiFi networks, and since it's one of the key features of the application, I took the responsibility to find a viable solution.

During my research, I discovered that most devices offered built-in support for connecting via scanned QR codes, but this functionality was spread across different Android APIs (known as 'Intents'). To address this, I compiled a comprehensive list of APIs for major device brands and implemented them within a unified interface and singleton class. After regress testing on multiple devices, we achieved a success rate of 90% compatibility across Android devices, and also included support for previous and upcoming Android versions, so all external Wi-Fi connections can be managed from one single solution The following year, I was reassigned to work on a different section of the application with a new team, primarily on security, device configuration, extender setup, speed testing, and Advanced web protection. Helped to expedite the development process; I implemented the flutter user interface in accordance with the new design specifications, improved the responsive layout, and given 100% priority improve the user accessibility. Additionally, I improved testing by adding unit and integration tests and helped the testing team set up Appium-based automated tests. As a result, the module had 99% more testing coverage.
