Usage

Whenever you want to use it within React Native code now you can: import Orientation from 'react-native-orientation-locker';

import Orientation from 'react-native-orientation-locker';


  _onOrientationDidChange = (orientation) => {
    if (orientation == 'LANDSCAPE-LEFT') {
      //do something with landscape left layout
    } else {
      //do something with portrait layout
    }
  };

  componentWillMount() {
    //The getOrientation method is async. It happens sometimes that
    //you need the orientation at the moment the js starts running on device.
    //getInitialOrientation returns directly because its a constant set at the
    //beginning of the js code.
    var initial = Orientation.getInitialOrientation();
    if (initial === 'PORTRAIT') {
      //do stuff
    } else {
      //do other stuff
    }
  },

  componentDidMount() {

    Orientation.lockToPortrait(); //this will lock the view to Portrait
    //Orientation.lockToLandscapeLeft(); //this will lock the view to Landscape
    //Orientation.unlockAllOrientations(); //this will unlock the view to all Orientations

    //get current orientation
    /*
    Orientation.getOrientation((orientation)=> {
      console.log("Current Device Orientation: ", orientation);
    });
    */

    Orientation.addOrientationListener(this._onOrientationDidChange);
  },

  componentWillUnmount: function() {
    Orientation.removeOrientationListener(this._onOrientationDidChange);
  }
