PreloadPageView is a Flutter widget that extends PageView to automatically preload the page before and after the currently visible page. This enhances scrolling performance by loading content in advance, reducing lag during navigation. Ideal for media-heavy or dynamic content lists, it ensures smooth transitions between pages. The package supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux, making it versatile for cross-platform applications. It integrates seamlessly with existing PageView workflows without requiring significant code changes.
