Dart Google Drive Realtime
This project is a library to use Google Drive Realtime API from dart scripts.
It uses JS Interop library and its scoped approch to prevent memory leaks. You can have a look at Js Interop documentation for more informations.
Usage
To use this library in your code :
- add a dependency in your
pubspec.yaml:
dependencies:
google_drive_realtime: ">=0.0.1 <1.0.0"- add import in your
dartcode :
import 'package:google_drive_realtime/google_drive_realtime.dart';
// for databinding part
import 'package:google_drive_realtime/google_drive_realtime_databinding.dart';- Follow the steps described at Create a Realtime Application.
How to
Define custom collaborative objects
Build a Collaborative Data Model explains how to define custom objects in javascript. With this package, you can do almost the same things.
- Define your own CollaborativeObject : it's mainly a wrapper of a javascript object. The
registerType()static function allows to define the type.
class Task extends rt.CollaborativeObject {
static const NAME = 'Task';
/**
* Register type as described in https://developers.google.com/drive/realtime/build-model#registering_and_creating_custom_objects
* This method must be call only one time before the document is load.
*/
static void registerType() {
js.context.Task = new js.Callback.many((){});
rtc.registerType(js.context.Task, NAME);
js.context.Task.prototype.title = rtc.collaborativeField('title');
js.context.Task.prototype.done = rtc.collaborativeField('done');
}
/// create new collaborative object from model
Task(rt.Model model) : this.fromProxy(model.create(NAME).$unsafe);
String get title => $unsafe.title;
bool get done => $unsafe.done;
set title(String title) => $unsafe.title = title;
set done(bool done) => $unsafe.done = done;
}Have a look on custom-task example for more details.
- Register this type before the document is loaded by calling
registerType().
