Hi, I am developing a React Native app.

I run a demo with GCanvas in iOS device. I got a error was

failed to load bundle(http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false) with error:(/Users/James/GCanvasDemo/node_modules/gcanvas.js/src/index.js: Unknown plugin "transform-decorators-legacy" specified in "/Users/James/GCanvasDemo/node_modules/gcanvas.js/.babelrc" at 2, attempted to resolve relative to "/Users/James/GCanvasDemo/node_modules/gcanvas.js" (null))

try to add plugins in your .babelrc like:

{
  "presets": ["react-native"],
  "plugins": [
    "transform-decorators-legacy"
  ]
}

@349989153 really appreciate your help.
GCanvas.js 0.0.8 has a .babelrc, so need install corresponding presets and plugins.
