The article walks through a magazine-style product detail demo that combines a Flutter native shell with an H5 section rendered by HarmonyOS ArkWeb on a single page, connected via a custom bidirectional JSBridge that exposes login state, device info, Toast and file picker to the web layer. The author also recounts two pitfalls—an instant crash at launch and a silently failing copy action—making it a hands-on field report for developers adapting Flutter to HarmonyOS.
