Invariant Violation: Native component for "RNSketch" does not exist
Hi! Maybe there is something wrong with my app, since I've tried a few other ways to daw an image / capture a signature and have been getting the same error. 

Here's my system info:
Environment:
  OS: macOS High Sierra 10.13.4
  Node: 9.5.0
  Yarn: 1.3.2
  npm: 5.6.0
  Watchman: Not Found
  Xcode: Xcode 9.3.1 Build version 9E501
  Android Studio: 3.1 AI-173.4720617

Packages: (wanted => installed)
  react: 16.3.1 => 16.3.1
  react-native: ^0.55.4 => 0.55.4

And full rundown of the error I am getting:
Invariant Violation: Native component for "RNSketch" does not exist

This error is located at:

    in AppContainer (at renderApplication.js:32)


Not doing any super special:
1. npm start
2. "R" to refresh
3. "a" for my android emulator
4. Expo starts up and I get the above error.

I should also note that I am using the example code in its entirety to try to minimize the possibility I am doing something silly ("Usage" @ https://github.com/jgrancher/react-native-sketch).

Any help is appreciated!
