Double white page flash on page

[amitjain28]

Double white page flash on pages when loading. it is clearly visible on Desktop and Mobile.
How can i remove it ?
Is this due to AOT or angular pre-rendering ?

Do you have Http calls on that page?
You either need to setup the TransferState Http, or you need to setup your RouterModule options.

RouterModule.forRoot([ /* your routes */, {
  preloadingStrategy: PreloadAllModules,
  initialNavigation: 'enabled'
});

I've tried that solution also but issue still exist.

You can check described issue here angular/angular#23427

If there is any external script you are loading, use async attribute to solve the flickering issue.
