React Native DualScreenInfo for Surface Duo

  • Article

DualScreenInfo is a non-visual helper that provides information about the device so that your code and layouts can adapt to dual-screens. It contains the following methods:

  • isDualScreenDevice – check this before accessing other dual-screen-specific APIs.
  • isSpanning – whether the app is on one or two screens.
  • windowRects – the bounds of the two display rectangles (excluding the hinge area).
  • didUpdateSpanning – event listener so your code can respond when the app is spanned or moved to a single screen.

Installation
