getPropertyType method Null safety

String? getPropertyType(
  1. String tagName,
  2. String property,
  3. [String? elementNs = '']
)

Allows web developers to check whether a Trusted Type is required for a property, and if so which one. var null = TrustedTypePolicyFactory.getPropertyType(tagName,property, elementNS);

Implementation

external String? getPropertyType(String tagName, String property,
    [String? elementNs = '']);
