// React Native WebView cannot load external JS files, however it can load
|
|
// arbitrary JS via the injectedJavaScript property. So we use this to load external
|
|
// files: First here we convert the JS file to a plain string, and that string
|
|
// is then loaded by eg. the Mermaid plugin, and finally injected in the WebView.
