pixels convert to density-independent pixels.
Default UI design size is based on 1280x720.
npm install react-native-px2dp --save
import px,{px2dp} from 'react-native-px2dp';
const style = {
width: 720 * px,//UI height size is 1280.
}
const otherStyle = {
width: 720 * px2dp(480),//UI height size is 960.
}
