+You can use the __whereMatchesKeyInQuery__ method to get objects where a key matches the value of a key in a set of objects resulting from another query. For example, if you have a class containing sports teams and you store a user’s hometown in the user class, you can issue one query to find the list of users whose hometown teams have winning records. The query would look like::
+
+```dart
+QueryBuilder<ParseObject> teamQuery =
+    QueryBuilder<ParseObject>(ParseObject('Team'))
+      ..whereGreaterThan('winPct', 0.5);
+

+      ..whereMatchesKeyInQuery('hometown', 'city', teamQuery);
+
+var apiResponse = await userQuery.query();
+```
+
+Conversely, to get objects where a key does not match the value of a key in a set of objects resulting from another query, use __whereDoesNotMatchKeyInQuery__. For example, to find users whose hometown teams have losing records:
+
+```dart
+QueryBuilder<ParseObject> teamQuery =
+    QueryBuilder<ParseObject>(ParseObject('Team'))
+      ..whereGreaterThan('winPct', 0.5);
+
+QueryBuilder<ParseUser> losingUserQuery =

+      ..whereDoesNotMatchKeyInQuery('hometown', 'city', teamQuery);
+
+var apiResponse = await losingUserQuery.query();
+```
+
+To filter rows based on objectId’s from pointers in a second table, you can use dot notation:
+```dart
+QueryBuilder<ParseObject> rolesOfTypeX =

+## File
+There are three different file classes in this SDK:
+- `ParseFileBase` is and abstract class and is the foundation of every file class that can be handled by this SDK.
+- `ParseFile` (former the only file class in the SDK) extends ParseFileBase and is by default used as the file class on every platform but web.
+This class uses a `File` from `dart:io` for storing the raw file.
+- `ParseWebFile` is the equivalent to ParseFile used at Flutter Web.
+This class uses an `Uint8List` for storing the raw file.
+
+These classes are used by default to represent files, but you can also build your own class extending ParseFileBase and provide a custom `ParseFileConstructor` similar to the `SubClasses`.
+
+Have a look at the example application for a small (non web) example.
+
+
+```dart
+//A short example for showing an image from a ParseFileBase
+Widget buildImage(ParseFileBase image){
+  return FutureBuilder<ParseFileBase>(
+    future: image.download(),
+    builder: (BuildContext context,

+        }
+      } else {
+        return CircularProgressIndicator();
+      }
+    },

+//libraries: image_picker (https://pub.dev/packages/image_picker), image_picker_for_web (https://pub.dev/packages/image_picker_for_web)
+PickedFile pickedFile = await ImagePicker().getImage(source: ImageSource.gallery);
+ParseFileBase parseFile;
+if (kIsWeb) {
+  //Seems weird, but this lets you get the data from the selected file as an Uint8List very easily. 
+  ParseWebFile file = ParseWebFile(null, name: null, url: pickedFile.path);
+  await file.download();
+  parseFile = ParseWebFile(file.file, name: file.name);
+} else {
