sentry-dart/dart/lib/src/event_processor/enricher/flutter_runtime.dart

Line 44 in 9e18a68

static const String? version = bool.hasEnvironment('FLUTTER_VERSION')

should be at least 3.33.0-0.2.pre or higher.

Ideally, you also make a check for bool.hasEnvironment('FLUTTER_VERSION') so that it tree shakes better. Calling a property on dynamic basically disables tree shaking for that property on any class. And the FLUTTER_VERSION dart define was introduced just one major Flutter version before this, which should already improve tree shaking quite a lot for most Flutter versions.
