Today, we’re announcing that we have updated AWS Amplify’s tools and libraries for Flutter to support null safety for all of our use cases. Flutter developers can now enjoy all the easy-to-integrate Amplify functionality with higher reliability and improved developer ergonomics. Sound null safety is a Dart language feature in which code is non-nullable by default and turns runtime null-dereference errors into edit-time analysis errors. This enables developers to reduce bugs in their code and benefit from performance improvements through smaller binaries and faster execution.
