performanceTiming top-level property

dynamic get performanceTiming

A legacy interface kept for backwards compatibility and contains properties that offer performance timing information for various events which occur during the loading and use of the current page. You get a PerformanceTiming object describing your page using the window.performance.timing property.

Implementation

_i2.dynamic get performanceTiming => _i4.getProperty(
      _self,
      'PerformanceTiming',
    );
