intervention_reporting library Null safety
- The interface of the Reporting API represents the body of an intervention report. An intervention report is generated when usage of a feature in a web document has been blocked by the browser for reasons such as security, performance, or user annoyance. So for example, a script was been stopped because it was significantly slowing down the browser, or the browser's autoplay policy blocked audio from playing without a user gesture to trigger it. A deprecation report is generated when a deprecated feature (for example a deprecated API method) is used on a document being observed by a ReportingObserver. In addition to the support of this API, receiving useful intervention warnings relies on browser vendors adding these warnings for the relevant features.
