4.1.0-nullsafety.1

• Bump: sentry-android to v4.3.0 (#343)
• Fix: Multiple FlutterError.onError calls in FlutterErrorIntegration (#345)
• Fix: Pass hint to EventProcessors (#356)
• Fix: EventProcessors were not dropping events when returning null (#353)

Breaking Changes:

• Fix: Plugin Registrant class moved to barrel file (#358)
  • This changed the import from import 'package:sentry_flutter/src/sentry_flutter_web.dart';
    to import 'package:sentry_flutter/sentry_flutter_web.dart';
  • This could lead to breaking changes. Typically it shouldn't because the referencing file is auto-generated.
• Fix: Prefix classes with Sentry (#357)
  • A couple of classes were often conflicting with user's code.
    Thus this change renames the following classes:
    • App -> SentryApp
    • Browser -> SentryBrowser
    • Device -> SentryDevice
    • Gpu -> SentryGpu
    • Integration -> SentryIntegration
    • Message -> SentryMessage
    • OperatingSystem -> SentryOperatingSystem
    • Request -> SentryRequest
    • User -> SentryUser
    • Orientation -> SentryOrientation
