Overview
webview_flutter_plus extends the webview_flutter package to enable loading local HTML, CSS, and JavaScript files directly from assets or as strings. It simplifies embedding static web content within Flutter apps without requiring an internet connection. The package supports advanced features like custom headers, JavaScript channel communication, and seamless integration with Flutter’s widget system. Ideal for offline documentation, in-app tutorials, or hybrid UI components that rely on web technologies.
