Key terms and concepts in web development, AI, and software engineering explained in plain language.
A WebView is an embeddable browser component that renders web content (HTML, CSS, JavaScript) inside a native mobile application. It allows developers to reuse existing web code within a native app shell, commonly used for displaying rich content, integrating web-based features, or building hybrid apps. While convenient, WebView-heavy apps typically have worse performance and a less native feel compared to truly native or React Native/Flutter approaches.
In Flutter, the widget tree is the hierarchical structure of nested widgets that defines the entire UI of an application. Everything in Flutter is a widget — from layout structures like `Column` and `Row` to styling wrappers like `Padding` and `Theme` to interactive elements like `GestureDetector`. Flutter maintains three parallel trees (widget, element, and render object) that work together to efficiently rebuild only the parts of the UI that actually changed when state updates.
A wireframe is a low-fidelity visual representation of a user interface that outlines structure, layout, and content hierarchy without detailed styling or colors. Wireframes focus on what elements appear on a page and how they are arranged, serving as a blueprint before visual design begins. They help teams align on functionality and user flow early in the process, when changes are cheapest to make.
