About This Article
Building cross-platform apps meant developers had to manually check for null references constantly. These checks added runtime overhead and slowed performance.
Flutter 2.2 made sound null safety the default for new projects. The Dart compiler can now eliminate null checks at runtime by analyzing types statically.
The ecosystem moved quickly to adopt null safety. About 5,000 packages were updated to support it, which improved app performance without requiring extra work from developers.
