flutter boost : 4.1.1

Flutter 3.3.7 • channel stable • https://github.com/flutter/flutter.git
Framework • revision e99c9c7cd9 (6 周前) • 2022-11-01 16:59:00 -0700
Engine • revision 857bd6b74c
Tools • Dart 2.18.4 • DevTools 2.15.0

Start at boost_channel.dart:45 and trace the callers in boost_channel.dart:51, boost_lifecycle_binding.dart:103, and flutter_boost_app.dart:623. Reproduce or inspect the container-show flow using the reported Flutter 3.3.7 and FlutterBoost 4.1.1 versions; done means the reported null-value crash no longer occurs in that flow.
