Contributing

Contributions are very welcome! Current limitations of this plugin:

The modifications to the native files are all accomplished by reading the existing contents of the document, searching for an existing line to anchor around, inserting the modification, and then saving the file.

If the structure/contents/spelling of these default files change in future versions of react native or expo in any way, these plugin modifications will fail.

For example, android/settings.gradle references the line:

include ':app'

android/app/build.gradle references the line:

def isGifEnabled = (findProperty('expo.gif.enabled') ?: "") == "true";

android/app/proguard-rules.pro references the line
