With --enable-asserts, does automatic debug assertion insertion: https://github.com/dart-lang/language/blob/master/accepted/future-releases/nnbd/feature-specification.md#automatic-debug-assertion-insertion Without --enable-asserts, does a NullCheck instead of an assert. Change-Id: I57b8c9ce9e7605b9d2355b1d96a10db3fd631917 Fixes: 42403 Change-Id: I57b8c9ce9e7605b9d2355b1d96a10db3fd631917 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/156044 Commit-Queue: Stephen Adams <sra@google.com> Reviewed-by: Mayank Patke <fishythefish@google.com> Reviewed-by: Nicholas Shahan <nshahan@google.com>
