Known Issues

  • closeAction is not supported on Web at this point in time, this is due to the iframe absorbing all clicks before the button detects them. For more info see https://github.com/flutter/flutter/issues/54027.
  • Some widgets such as clipRRect will not affect the WebView on mobile, and will not change the widget. This works on web though.
  • On mobile, onFinishedLoading() will be called multiple times.
