frameId property
      
      int
      get
      frameId
      
    
    
The value 0 indicates that the request happens in the main frame; a
positive value indicates the ID of a subframe in which the request
happens. If the document of a (sub-)frame is loaded (type is
main_frame or sub_frame), frameId indicates the ID of this frame,
not the ID of the outer frame. Frame IDs are unique within a tab.
Implementation
int get frameId => _wrapped.frameId;
      
      set
      frameId
      (int v) 
      
    
    
    
Implementation
set frameId(int v) {
  _wrapped.frameId = v;
}
