File api is incomplete (e.g. getFreeDiskSpace, writeFile) and docs is incomplete (e.g. readAstext)

I'm using Ionic 2 latest beta (37) and trying to work with files (File plugin @ ionic-native).

Some methods (readDire, writeDir, ...) work normally.
However others are either missing (not implemented as per also in the Typescript definitions), for example:

• getFreeDiskSpace
• writeFile

or lacking a proper documentation. For example...

• readAsText: how to do it without overriding a file? (apparently the only way to get a FileEntry is a createFile/writeFile but both either override the file or throw an error if it exists and replace = false). Eventually refer to my SO question at http://stackoverflow.com/questions/39494174/how-to-get-a-fileentry-to-then-use-readastext-in-cordova-ionic2

I understand this is still a beta but I was wondering if this is intentional of a "work in progress" (in which case feel free to close this issue)?
Thank you

Actually getfreediskapace is implemented in the native code but has no JavaScript interface in the plugin itself, been this way forever, you can run a Cordova.exec command to access the native function, this could be implemented in the ionic native wrapper I guess

This is all that is required and it could be implemented in the ionic-native wrapper for the getFreeDiskSpace call. The platform detection is to adjust the returned result to be in a consistent format on both android and ios.

//file plugin has no js interface to getfreediskspace method
//use cordova.exec directly to access it.
  getFreeDiskSpace(): number {
    var freeDiskSpace: number;
    cordova.exec(function(result) {
      //console.log(result);
      if(isAndroid){
        freeDiskSpace = (result*1024);
      }
      if(isIos){
        freeDiskSpace = result;
      }
      return freeDiskSpace;
    }, function(error) {
      //console.log(error);
    }, "File", "getFreeDiskSpace", []);
  }

@ghenry22 thanks for suggestion, just implemented this. However, I'm just returning back the raw response from the native code, not modifying anything based on platform.

@dragGH102 @ghenry22 Can you try with the latest version v2.2.2 and report back if you still have any issue? Thanks.
