Changes for Flutter 2

[AndrewM-]

To get the project to work in Flutter 2 I had to make a couple of changes to the supporting packages:

1. • In picture_stream.dart, I changed the word 'DiagnosticableMixin' to 'Diagnosticable'
2. • In picture_provider.dart I chanded line 49 or 50 to locale: context != null ? Localizations.localeOf(context) : null,

For item 2, Flutter 2 handles nulls differently and the NullOK flag has to be removed. More info here: https://docs.google.com/document/d/1LKBL0S1uyhACDiUXILhLKFZH8Cpl_w3mXjHgaE8_--U/edit#heading=h.pub7jnop54q0

To get at these files, find the import statement in home_screen.dart import 'package:flutter_svg/flutter_svg.dart'; and use the goto definition menu option (VS Code). This will take you to flutter_svg.dart which lists the packages in items 1 and 2. Open the definition to see the code.

Hi! As I've said at #2, the author said the license it's MIT, so, if you have these changes working still and have the time, submit a pull request, maybe someone else wants them and it would be easier to find them. Or even just fork this repo and tell people about it.
