Why use the native sheet

Rows of social buttons rarely match each user's apps; the OS sheet shows real apps and frequent contacts (Apple, n.d.; Android Developers, n.d.). Many buttons slow choice per Hick's law (Hick, 1952) and cause choice overload. Sheets usually appear as a bottom sheet.

Previews and links

Android can add title and thumbnail previews (Android Developers, n.d.), and web pages use Open Graph data. Emotionally arousing content is shared more (Berger & Milkman, 2012), so place share near moments of delight or achievement.

navigator.share() needs a user gesture and is not universal (MDN, n.d.; web.dev, n.d.); fall back to copy-link. Match platform share icons and label them 'Share' per WCAG 2.2 (W3C, 2023) 4.1.2.

Hick's LawWhat Hick's law is: the principle that choice reaction time rises logarithmically with the number of alternatives, its origin in Hick and Hyman's experiments, the information-theoretic account, links to Fitts's law, exceptions and cognitive models.🧠 Psychology Choice OverloadWhat choice overload is: too many options leading people to defer or give up on choosing and to feel less satisfied. Covers the jam study, retirement fund research, Schwartz's paradox of choice and maximizers, a null meta-analysis and one identifying moderators.🧠 Psychology Bottom SheetA bottom sheet slides up from the screen edge to show extra information or choices. Covers standard and modal sheets, detents, drag-to-dismiss, thumb-reach evidence, accessibility and common mistakes.⚙️ Engineering & Technology AI Search Algorithms: A* and MinimaxAI search algorithms explained: state-space search, breadth-first and depth-first search, Dijkstra, heuristics and A* (admissibility, consistency), game trees, minimax and alpha-beta pruning, based on the original papers.⚙️ Engineering & Technology
