Worked on updating the Flutter web renderer documentation within the flutter/website repository to reflect recent changes in rendering technologies. Focused on replacing outdated references to 'HTML and CanvasKit' with the current options, 'CanvasKit and Skwasm,' ensuring that the documentation accurately guides developers on available web renderer choices. Utilized Markdown for precise documentation updates and applied strong attention to detail to maintain consistency across the content. This work improved onboarding and developer guidance by aligning documentation with the latest Flutter web rendering stack. The contribution centered on documentation skills and addressed evolving technology standards without introducing new code features or bug fixes.
