leancloudFlutterPlugin.setRegion(LeancloudCloudRegion.NorthChina);

Initialize Leancloud

leancloudFlutterPlugin.initialize(appId, appKey);

Create and update an Object

Import: import 'package:leancloud_flutter_plugin/leancloud_object.dart';

// Create
AVObject object = new AVObject("YOUR_OBJECT");
object.put("FIELD_NAME", "VALUE"); // String
object.put("OR_INT", 10); // int
object.put("OR_BOOLEAN", true); // boolean
object.put("OR_FLOAT", 10.01); // float
object.save().then((object) {
  // Saved
  print(object);
  
  // and Update
  object.put("description", "updated!");
  object.save().then((object) {
    // Updated
    print(object);
  });
});

If your update your object, {"code":403,"error":"Forbidden writing by object's ACL."} happened, then please check leancloud data's ACL field.

Delete an Object

// object is an AVObject
object.delete().then((isDeleted) {
  // Deleted
  if (isDeleted) {
    object = null; // you should set ref to null manually if you don't using this object
    print("Deleted!");
  }
});

Query an Object

Import: import 'package:leancloud_flutter_plugin/leancloud_query.dart';

// query by object_id
AVQuery avQuery = new AVQuery("DemoObject");
avQuery.get("OBJECT_ID").then((object) {
  print("Queryed!");
});

// query objects
AVQuery avQuery = new AVQuery("DemoObject");
avQuery.whereEqualTo("KEY", "VALUE"); // string value
avQuery.whereNotEqualTo("KEY", 10); // int value
avQuery.whereGreaterThan("KEY", true); // bool value
avQuery.whereGreaterThanOrEqualTo("KEY", "VALUE");
avQuery.whereLessThan("KEY", "VALUE");
avQuery.whereLessThanOrEqualTo("KEY", "VALUE");
avQuery.find().then((objects) {
  print("All Objects Queryed!");
});
