How do I import NativeMethodsMixin?

I did import {NativeMethodsMixin} from 'react-native' but it is undefined. here is exponent example. You will get redbox. https://snack.expo.io/HJq_dCGTl

I think this kind of import only work inside react native project (powered by haste?) For the application everything should come from react-native module. tried your suggestion and failed: https://snack.expo.io/SynGpBXax @hramos

@evollu I have a tricky approach. We just use several methods of the object of NativeMethodsMixin.

const NativeMethodsMixin = {
  measure: function(callback) {
    UIManager.measure(findNumericNodeHandle(this), mountSafeCallback(this, callback));
  },
  measureInWindow: function(callback) {
    UIManager.measureInWindow(findNumericNodeHandle(this), mountSafeCallback(this, callback));
  },
  measureLayout: function(relativeToNativeNode, onSuccess, onFail) {
    UIManager.measureLayout(findNumericNodeHandle(this), relativeToNativeNode, mountSafeCallback(this, onFail), mountSafeCallback(this, onSuccess));
  },
  setNativeProps: function(nativeProps) {
    injectedSetNativeProps(this, nativeProps);
  },
  focus: function() {
    TextInputState.focusTextInput(findNumericNodeHandle(this));
  },
  blur: function() {
    TextInputState.blurTextInput(findNumericNodeHandle(this));
  }
};

I copy the dependency of NativeMethodsMixin to a single file.

So, I can use it anywhere.
