Ionic 2 - FileEntry.file success callback issue


#1

Hello,
I get a strange behavior when I try to read file attributes.
The following method gets the URI from a filepicker.
I try to read file attributes thanks to
FilePath
FilePath.resolveNativePath
File.resolveDirectoryUrl
File.getFile
fileEntry.file

when on device I log tmpFile.size, It returns size of the file, on desktop, the file attribute is not even defined, so it blocks transpilation : what’s wrong here ?
is there an issue in FileEntry.file success callback definition ? typescript linting fails.

FileChooser.open()
.then(uri => {
console.log(“uri”, uri);

        this.fileManagerService.readFile(uri);

    })
    .catch(e => console.log(e));

readFile(uri:string): void {

        console.log("uri", uri);
      
        FilePath.resolveNativePath(uri).then(natifUrl => {

          let path = natifUrl.substring(0, natifUrl.lastIndexOf('/'));
          let fileName = natifUrl.substring(natifUrl.lastIndexOf('/') + 1, natifUrl.length );

            File.resolveDirectoryUrl(path) // readAsText
            .then(directoryEntry=> {
                
                File.getFile(directoryEntry, fileName, {} ) // readAsText
                .then(fileEntry=> {

                fileEntry.file(tmpFile=> {
                
                console.log('tmpFile', tmpFile);
				console.log('tmpFile.size', tmpFile.size);	
				  
                }, ((error:FileError) => console.log(error)));


                })
                .catch(err=>{
                console.log("lecture de contenu error01", err);
                }); 
            })                

        })

    .catch(e => console.log(e));
  }

I raised an issue, https://github.com/driftyco/ionic/issues/10181
already closed, but without explaination.

If someone can elaborate a bit on how it’s possible to get file information : mime type, size.
thanks,
regards,
