Ionic 2 File Plugin usage examples
<p>Does anyone have complete examples about how to use the Cordova Native File Plugin in a Ionic 2/Angular 2 project?</p>

<p>I installed this plugin but the documentation don't seems to make much sense to me due the fact it is fragmented and lacks of a complete example, including all needed imports.</p>

<p>For example, the following example don't shows where objects like LocalFileSystem or window came from.</p>

<pre><code>window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fs) {

    console.log('file system open: ' + fs.name);
    fs.root.getFile("newPersistentFile.txt", { create: true, exclusive: false }, function (fileEntry) {

        console.log("fileEntry is file?" + fileEntry.isFile.toString());
        // fileEntry.name == 'someFile.txt'
        // fileEntry.fullPath == '/someFile.txt'
        writeFile(fileEntry, null);

    }, onErrorCreateFile);

}, onErrorLoadFs);
</code></pre>

<p>For example, I need to crate a property file. First I need to check if a file exists on app sandbox storage area, if don't exists I must create it. Then I must open the file write data and save it . How could I do that?</p>
