findAllAsync method Null safety

Future<void> findAllAsync(
  1. {required String find}
)

Finds all instances of find on the page and highlights them. Notifies WebView.onFindResultReceived listener.

find represents the string to find.

NOTE: on Android, it finds all instances asynchronously. Successive calls to this will cancel any pending searches.

NOTE: on iOS, this is implemented using CSS and Javascript.

Implementation

Future<void> findAllAsync({required String find}) async {
  Map<String, dynamic> args = <String, dynamic>{};
  args.putIfAbsent('find', () => find);
  await _channel.invokeMethod('findAllAsync', args);
}
