Andrew Brogdon of the Flutter team posted this informal survey to the FlutterDev subreddit, asking for feedback on migration to null safety. (Apparently there hasn't been the flurry of bug reports or other feedback the team was expecting, and this may be causing concern that developers aren't yet attempting the migration.)
My take on the responses so far is that code dependencies might end up being a fairly large hurdle here. After all, if the code which my code depends on hasn't yet been migrated to null safety, it's just one more barrier to getting my own code moved over.
Hopefully this will all work itself out fairly quickly, but if YOU have feedback for Andrew and the Dart/Flutter team on this important topic, head on over to reddit and respond!
Great news here from the Flutter team, which has just released version 1.0 of the integration test plugin.
The new plugin, which is described as "a simpler way to test your Flutter apps that also supports Firebase Test Lab," aims to solve a number of problems with Flutter driver testing.
Assuming it can fulfil its goals, this plugin seems very promising. This article by Chris Sells should help get you started.
