To be able to load your local files (assets, js, css, etc.), you need to add them in the assets section of the pubspec.yaml file, otherwise they cannot be found!

Example of a pubspec.yaml file:

...

# The following section is specific to Flutter.
flutter:

 # The following line ensures that the Material Icons font is
 # included with your application, so that you can use the icons in
 # the material Icons class.
 uses-material-design: true

 assets:
   - assets/index.html
   - assets/css/
   - assets/images/

...

Example of a main.dart file:

...
inAppBrowser.openFile(assetFilePath: "assets/index.html");
...

headers: The additional headers to be used in the HTTP request for this URL, specified as a map from name to value.

options: Options for the PlatformInAppBrowser.

settings: Settings for the PlatformInAppBrowser.

Implementation

@override
Future<void> openFile(
    {required String assetFilePath,
    // ignore: deprecated_member_use_from_same_package
    @Deprecated('Use settings instead') InAppBrowserClassOptions? options,
    InAppBrowserClassSettings? settings}) async {
  assert(assetFilePath.isNotEmpty);

  Map<String, dynamic> args =
      _prepareOpenRequest(options: options, settings: settings);
  args.putIfAbsent('assetFilePath', () => assetFilePath);
  await _staticChannel.invokeMethod('open', args);
}
