WebViewController.fromPlatformCreationParams constructor

WebViewController.fromPlatformCreationParams(PlatformWebViewControllerCreationParams params, { void onPermissionRequest(WebViewPermissionRequest request)?, })

Constructs a WebViewController from creation params for a specific platform.

onPermissionRequest: A callback that notifies the host application that web content is requesting permission to access the specified resources. To grant access for a device resource, most platforms will need to update their app configurations for the relevant system resource.

For Android, you will need to update your AndroidManifest.xml. See https://developer.android.com/training/permissions/declaring

For iOS, you will need to update your Info.plist. See https://developer.apple.com/documentation/uikit/protecting_the_user_s_privacy/requesting_access_to_protected_resources?language=objc.

Below is an example of setting platform-specific creation parameters for iOS and Android:

PlatformWebViewControllerCreationParams params =
    const PlatformWebViewControllerCreationParams();

if (WebViewPlatform.instance is WebKitWebViewPlatform) {
  params = WebKitWebViewControllerCreationParams
      .fromPlatformWebViewControllerCreationParams(
    params,
  );
} else if (WebViewPlatform.instance is AndroidWebViewPlatform) {
  params = AndroidWebViewControllerCreationParams
      .fromPlatformWebViewControllerCreationParams(
    params,
  );
}

final WebViewController webViewController =
    WebViewController.fromPlatformCreationParams(
  params,
);

Implementation

WebViewController.fromPlatformCreationParams(
  PlatformWebViewControllerCreationParams params, {
  void Function(WebViewPermissionRequest request)? onPermissionRequest,
}) : this.fromPlatform(
        PlatformWebViewController(params),
        onPermissionRequest: onPermissionRequest,
      );
