Dimensions
Respond to changes in the viewport dimensions.
Dimensions may change (e.g., due to device rotation) so any rendering logic or styles that depend on these constants should try to call this function on every render, rather than caching the value.
import { Dimensions } from 'react-native';API
Static methods
get (string: "window" | "screen") => Dimension
Get a dimension (e.g., window or screen).
set (dimensions: { window: Dimension, screen: Dimension }) => void
This should only be called server-side with an estimate for initial dimensions to be used when pre-rendering pages on the server.
addEventListener (type: ?string, listener: (dimensions) => void) => ?EmitterSubscription
Add a listener to Dimensions changes. Listen to the "change" event type. The handler is called with the dimensions state.
removeEventListener (type: ?string, listener: (dimensions) => void) => void
Remove a listener from Dimensions changes.
