Example wallet is breaking on flutter run

[kamalpreet-singh01]

When trying to run the example > wallet locally, it fails by throwing the following error:
Error (Xcode): ../../../../../.pub-cache/hosted/pub.dev/universal_html-2.2.2/lib/src/html/dom/element_subclasses.dart:2752:30: Error: The argument type 'String?' can't be assigned to the parameter type 'Object' because 'String?' is nullable and 'Object' isn't.
