simple Google Drive access with Dart - dart

Question

I am trying to read a basic text file(no authorization needed) from google drive with Dart. The code below returns a 400 Error. If the API_KEY is removed then a 403 error. I can input the file id into the Google get file reference page and it will return the metadata correctly.
Any Ideas would be great. Thanks
final url = "https://www.googleapis.com/drive/v2/files/FILE?key={API_KEY}";
var request = new HttpRequest();
request.on.loadEnd.add( (Event e)
{
if (request.status == 200)
{
var data = JSON.parse(request.responseText);
query("#file").text = data;
}
else
{
query("#file").text = "Error ${request.status}: ${request.statusText}";
}
});
request.open("GET", url);
request.send();

Your best bet is to use the drive_v2_api_client.
This can be done by setting up your google console apis with the following settings for localhost testing with DartEditor
Redirect URIs: http://127.0.0.1:3030/oauth2callback
JavaScript origins: http://127.0.0.1:3030
Then use the dart drive package drive_v2_api_client by putting the following depenencies in your pubspec.yaml file.
dependencies:
drive_v2_api_client:
git: git://github.com/Scarygami/dart_drive_v2_api_client.git
This example allows the client to get the fileid after the client has authenticated with the client id.
import 'dart:html';
import 'dart:json';
import "package:drive_v2_api_client/drive_v2_api_client.dart" as drivelib;
import "package:google_oauth2_client/google_oauth2_client.dart";
final CLIENT_ID = "<YOUR CLIENT ID FROM CONSOLE API>";
final SCOPES = [drivelib.Drive.DRIVE_FILE_SCOPE];
void main() {
var fileid = "1B_cGCNFjnK3dDriTMLsSS_zExfGFkQeewb3dcP4xSPg";
var auth = new OAuth2(CLIENT_ID, SCOPES);
var drive = new drivelib.Drive(auth);
drive.makeAuthRequests = true;
var loginButton = query("#login");
var output = query("#text");
loginButton.on.click.add((Event e) {
auth.login().then((token) {
output.appendHtml("Got Token ${token.type} ${token.data}<br><br>");
drive.files.get(fileid)
..then((data) {
output.appendHtml(data.toString());
});
});
});
}
