How I Fixed Flutter Web’s Annoying Page Reload Problem

Описание и применение

Используя flutter_web_storage, Flutter‑веб‑приложения сохраняют состояние и маршруты при перезагрузке, устраняя потерю данных и мерцание UI.

Задача

Flutter web apps lose in‑memory state and navigation history on page refresh, causing UX issues like lost form data, reset filters, stale admin views, and route loss.

Результат

The app now retains form drafts, filter selections, admin changes, and deep‑link routes after a browser refresh, with no startup flicker and instant cross‑tab sync.

Рабочий процесс

• 1. Add flutter_web_storage to pubspec.yaml
• 2. Import FlutterWebStorage and obtain instance
• 3. Use setString, setStringList, etc. to persist data synchronously in initState or constructors
• 4. Register WebRoutePreserverNavigatorObserver to restore routes on boot
• 5. Optionally listen to storage events for real‑time cross‑tab updates

Доказательства

flutter_web_storage bypasses the asynchronous microtask queue entirely
