Special items in this block: - checked_mode_helper is a helper library that needed extensive modifications. Fixing it up for Dart 2.0 meant simultaneously migrating its users in blocks 113 and 163. Renamed it to dynamic_type_helper to try to reflect what it's actually doing now. - Many minor breakouts of compile-time errors and conversion from static warnings.
