This article explains how to handle iOS Live Photo assets in Flutter by extracting the HEIC image and video components, synchronizing gesture‑driven scaling and translation, and managing playback during slide‑out and gesture interactions, complete with detailed code examples.
The article compares Android’s fragmented system‑level floating‑window permissions and lack of built‑in in‑app support with HarmonyOS’s simpler Application Sub‑Window approach, detailing how to obtain a WindowStage, create and configure a draggable sub‑window, handle gestures, and forward navigation and back‑press events to the main window.
This article demonstrates how to build a custom left‑swipe delete interaction for SwiftUI list cards by using DragGesture, state handling, visual cues, confirmation alerts, hint text, and haptic feedback, offering a more flexible alternative to the built‑in List deletion.
Flutter determines which widget handles a pointer by converting raw data into PointerEvents, hit‑testing the widget tree, and routing events through a GestureArena where recognizers compete, as illustrated by an image viewer that resolves conflicts between pinch‑zoom and horizontal drag using custom recognizers and boundary‑aware scrolling.
This article explains how to set up an Android Accessibility Service to perform black‑box automation testing, outlines its advantages over standard UiAutomator frameworks, details configuration steps, code examples, limitations, and provides guidance on selecting appropriate testing solutions.
The article presents a full system for capturing and replaying Flutter UI gestures, detailing how raw pointer data is processed, how gesture recognizers compete, how recordings wrap callbacks and generate synthetic touch packets, and how a timer‑driven replay reproduces user interactions for debugging.
The article explains the mathematical foundations and front‑end implementation of five common mobile gestures—drag, pinch, rotate, single‑finger pinch, and single‑finger rotate—using native touch events, vector calculations, and matrix transformations, and provides a lightweight library that emits incremental gesture events for easy integration.
