How big a list can be before the app crashes/freezes?

The data type of a list has

  • 5 numbers
  • 2 string
  • 2 DateTime
  • 2 boolean

On UI, I only show thumbnail size base64 string image and a name. How big the size of the list can be before app crashes/freezes?

Totally dependent on available device resources, but if you’re managing really big lists, look into Virtual Scroll.

Is there any way to check how much memory a page or a method call is consuming?
