Flutter stable channel issue - Error: The method 'ancestorStateOfType' isn't defined for the class 'BuildContext'.

[adam-weissert]

In the newest stable branch of flutter the build will fail with this error

../../Development/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_google_places-0.2.6/lib/src/flutter_google_places.dart:74:15: Error: The method 'ancestorStateOfType' isn't defined for the class 'BuildContext'.
 - 'BuildContext' is from 'package:flutter/src/widgets/framework.dart' ('../../Development/flutter/packages/flutter/lib/src/widgets/framework.dart').
Try correcting the name to the name of an existing method, or defining a method named 'ancestorStateOfType'.
      context.ancestorStateOfType(const TypeMatcher<PlacesAutocompleteState>());

Here's flutter doctor with it as well:

I'm aware of the changes in #140 and have tried this suggested fix as well as this one no avail.

I've upgraded the package to v0.3.0 and any of its dependencies, which resolved this issue, so I'm closing this issue
