Offline Resources Loading

WebF supports the https://, http://, file://, and assets:// protocols for fetching external resources.

`http://` and `https://` Protocols

Like web browsers, the standard method to fetch remote resources is through the HTTP protocol.

controller = WebFController(
  context,
);
controller.preload(WebFBundle.fromUrl('https://xxx.com/demo.html'));

This protocol is used to access any disk location with readable permissions, available on both desktop and mobile platforms.

controller = WebFController(
  context,
);
controller.preload(WebFBundle.fromUrl('file:///data/demo/demo.html'));

This protocol is used for resources bundled with Flutter assets.

controller = WebFController(
  context,
);
controller.preload(WebFBundle.fromUrl('assets:///assets/bundle.html'));
