How do I determine the screen size?

[MAHFIY_SIRLAR_MENING]

I wanted to know the length and width of the screen. Is there a method or extension?

You can use this extension.

Get Device Metrics → DisplayMetrics │ Resolution - Density - Font scaling

With this extension you can get various information about the screen → DisplayMetrics : screen dimensions, aspect ratio, pixel resolution, dp (or density-independent pixel, Android’s logical pixel), density, font scale, ... GetMetrics.aix (6.7 KB) [grafik]

Example - blocks
