Get a file base64 from the URI

i have been trying to get the base64 of a file. however i could not use the plugin for some reason.

window.resolveLocalFileSystemUrl(path, gotFile, fail);

This above code gives me a:

"Property 'resolveLocalFileSystemUrl' does not exist on type 'Window'."

error.

Is there any way to fix it? i have the plugin installed. Also, i have tried(from other stackoverflow answers) 

window.resolveLocalFileSystemUri(path, gotFile, fail);
window.resolveLocalFileSystemURL(path, gotFile, fail);
window.resolveLocalFileSystemURI(path, gotFile, fail);

OR if there is another way to retrieve the base64, please assist.

By the way, im using filechoose to open and choose the file.

i have solved the issue by re-installing the plugin.

getFileContentAsBase64(path, callback){
 window.resolveLocalFileSystemURL(path, gotFile, fail);

 function fail(e){
   alert('Cannot found requested file');
 }

 function gotFile(fileEntry){
   fileEntry.file(function (file){
     var reader = new FileReader();
     reader.onloadend = function(e){
       var content = this.result;
       callback(content);
     }
     reader.readAsDataURL(file);
   });
 }
}

the above code allows you to convert a dataURL(file/image/pdf anything) into base64.

you can call it by: 

getFileContentAsBase64(obj.toInternalURL().toString(), function (base64File) {
 console.log(base64file);
}

Thanks everyone for the help!

I haven't found anywhere default function name window.resolveLocalFileSystemUri it's a resolveLocalFileSystemURL

Try Below

resolveLocalFileSystemURL(path, function(entry) {
    var nativePath = entry.toURL();
    console.log('Native URI: ' + nativePath);
    document.getElementById('image').src = nativePath;
});

Source is here

Make sure you have installed file-transfer plugin.
