Support .flutterflowignore #11
Description
There is a TODO inside this extension to source code to support .flutterflowignore.
In our FF project, we had to make some modifications that FF does not support.
(Eg git-url-based pubspec dependencies, patches to gradle.properties, patches to Podfile).
Currently this extension is not usable with our project, because pulling files is destructive and will overwrite all of the local patches.
This would be a great feature and would make this extension usable to those who have custom modifications (typically done in a separate git branch).
